Dasa headwork

[trost66]

I just got my head back today from racer edge. Had them race port and flow the head. Had them istall titiamim valve, three angle valve job. Hopefully get it on this weekend. Can't wait to feel the difference. I will post some pictures of the stock head and the new one when I get the old head off.

[honduh440]

if u dont mind telling how much did that set ya back

[trost66]

1200for everything. Just have to bolt it on when I get it.

[trost66]

port and flow was 600
titiuam vavles 220
3 angle vavle job 175
New springs and keepers and he did somthing else I can't remember right now.

[jeepnrocks]

cant wait to hear how it performs

Wow that's expensive. I thought his porting was $400. Hopefully it will be worth it when you get to ride it. Keep us posted.

[trost66]

Ya he the prices on the internet are old. I think the price on there is for the recreational port not the race port. They said they haven't updated the site yet

[Jonas]

Bolt that thing on and let us know ASAP! Also, how long was the total turn around on it?

[chad502ex]

600 hmm

[MR.BIG]

Chad aren't you doing some port work now yourself?

[trost66]

600 counts the flow test. I think the port was 500 and 100 for the flow test

[chad502ex]

600 is fine if that is what you want. my friend spent $2000 for his Pro porting which he no longer runs,...

to each thier own!


Mr.Big, yes i do

[honduh440]

yeah keep us informed on how it does

[desratt]

cam??? degreeing???? shim?????

[trost66]

None of that. I have the 02 crf cam and he said that was a really gook cam for mx.

[lafinrat]

$175 for a valve job on four seats with new valves? wow!

[cals400ex]

chad, why does your friend not run that expensive port job anymore? who did the work?

cal, I was trying to convey that my friends DASA Pro port job was $2000 and that DASA no longer runs that Pro port. Dasa new pro port is different revision than my friends.

hope that helps.:cool:

[xsr_racing28c]

Chad what price range are you at for a mild port job for my 04 450?? I am looking into getting a port job done soon, and am playing with ideas. let me know, Jason

[cals400ex]

is the revised dasa pro port better or just more money?


trost, i am surprised dasa already has the head done. they are pretty booked.

[trost66]

They only had the head for about a week and a half. I shipped the head out on march 3. From IL to CA. I had it on my front porch the march 21. I thought that was pretty fast if you figure in the shipping to CA and back from CA

[chad502ex]

DASA doesn't sell the current Pro revision to anyone until the season is complete. so he says....

xsr.. pm sent

cal do you decide yet?

[cals400ex]

did i decide on the port yet you mean? i would like to see those graphs in the dyno section in HP vs RPM. i think i want you to do the work. i am trying to find the best option especially if i am putting down this much cash on something.....

well the springs should be here monday. heck, i have not even ordered the valves yet from ron. when i call he seems to be out of the shop. maybe i am calling at the wrong times. i really do want to get the better valves so i guess i will try my best to get ahold of him. i haven't call that much so i will try some more.

[trost66]

[cals400ex]

what kind of valves are those? is that the kibblewhile valve springs? is that just titanium intake?


definatly let us know how it runs?

[TRX450R1]

I think you're going to find that your machine is stupid fast!
Our DASA works engine is crazy powerfull. It runs smooth, starts easy and rips you off the seat.
I'll probrably be called a paid advertisement for Dan again, but we've had the engine back and the machine together for 2 months now, no problems.
We're just waiting for the race season to start!

[trost66]

That is what I wanted to here.

[TRX450R1]

Sounds like you've got a nice machine, I'm sure you'll like the port & polish. What kind of cam are you running?
Our engine was a full package deal from DASA, CRF conversion, 14.5:1 compression, taper-bored 41mm CF carb, DASA intake and pipe. All installed in CA except the pipe. Right out of the crate, 4 kicks, running.

[Jonas]

Has anyone put in the dirt bike valves yet and how did it go? I am going to have the exhaust valves oversized on mine a mil and try the dirtbike exhaust valves on my '06 as well as a port.

[trost66]

I just have the sparks aggresive drop in cam, sparks 13-8-1 piston and sparks exhaust

[trost66]

Taper boring the carg does that make a big difference

Well, did you try it out this weekend?

[trost66]

I didn't try it out this weekend. I'm goning to put it on this week. I wanted to race this weekend so I didn't tear it apart. I'm going to start on it tonignt

[chad502ex]

yes it does.

I can get taper boring on FCR carbs too.
Actually, I stumbled across a winning taper combo on my DRG carbs that has proven itself with its performance.

You know, too little or too much taper can be a bad thing on carbs....

Time to get off the sofa and get that thing put together.

[E.POWERSPORTS]

Any ride reviews on this build yet?

[trost66]

I got my head back on yesterday. The bad thing is that it smokes really bad. It didn't smoke at all before. The quad started on the second kick. It smoked a little gave it a little gas and it went away. About 1 min later it started to smoke again. It just kept getting worse and worse. It about filled up the garage with smoke. Somthing has to be wrong with the head. I raced the day before and no smoke at all. Put the head on and it smoked within a min. Dan put the new valves and everything back into it. He said when I get it just bolt it on. Any ideas.

[WhiteZee]

you used a new head gasket right?

[E.POWERSPORTS]

I'm sure you used a new head gasket but did Dan recommend replacing the cylinder base gasket at the same time?

[trost66]

I used a new headgasket but he didn't say anything about a basegasket

[WhiteZee]

if he never pulled the jug off theres no reason to replace the base gasket.

[trost66]

I just took the old head off and put the new on. Did nothing with the piston. It stayed in the same spot it was when I shut it off to put the head on. It has to be somthing in the head because it didn't smoke at all. As soon as I put the head on it smoked like crazy. The warmer it got the more it smoked.

[FHKracingZ]

Make sure your timing is dead on also albert. Maybe its something with your jetting with the new head? im not sure.

[shamisc]

Maybe the valve seals got damaged when they were removed and didn't get replaced with new ones??:confused: Could be a bent valve??? I would check back with DASA to see what they have to say!

[trost66]

I tried to call but he never called me back. Everything was brand new. I sent him a new head and he put new vavles, spring the works. I will try again tomarrow.

[shamisc]

Hopefully he'll help you out. That really sucks dude.

[Jonas]

How many more nuts do you have to take off to pull the cylinder off??? Is it not just sitting there on the case with four studs through it once you pull the head off??? That or bad valve stem seals?

[MR.BIG]

Did you find anything out yet? It sounds like bad valvestem seals.

[trost66]

He told me to ship it back to him and he would look it over.

[Jonas]

Any word yet?

[trost66]

I had to ship it back and he called and said the vavle seals were bad. Suppose to get it back tomorrow.

[Clove450R]

Steams seals will smoke when you first start then should be Ok. I think you have a bent valve effecting the seal or a bad guide.

JMO
Clove

[trost66]

Dan took it back apart and said the seal was bad. He said he didn't have time to finish it friday because of the race this weekend. Suppose to finish it up today and overnight it.

I have heard that before .he might have over ported it like mine was it only takes a few minutes to change the seals :rolleyes:

What did they do when they over ported your head. I think that is what they did. It looks like they used some opoxy to fix it. It looks like they over ported and there is a little bubble of apoxy coming out the top of the head by the intake vavle spring. I think that is why it took them so long to get it back to me. I am going to give them a call monday and get to the bottom of it.

[Yamahauler_04]

Epoxy is not always overporting.

Some motorbuilders will epoxy and port that to make the port exactly the way they want it.

It wouldn't surprise me at all if it was intentional and supposed to be there.

[trost66]

Wonder why there is a little bubble of apoxy poking though the top of the head by the intake vavle spring.

[370kingR]

IMO, absolutly NO port job is worth 600.00...period. Ive been there, done that, and have come to realize the only thing that heavy price tag got you is a pumped up sensation that its going to run so hard you wont be able to hang on.....

No doubt that there are many good porting people out there willing to do that job for way less, and its a very good possibility it would run great the first time you took it out of the box. Bad seals, over porting........youll never know because youll never get a straight answer.

If it was a valve seal, there is absolutly no reason that should be happening. A 1200 head certainly should come with new valve stem seals right?? No real way to screw them up.....

Over porting..well heck by now they should know where they can go to if they preach how exact to the thousandths of an inch they can port to......Ive heard many time how just a couple thou here or a couple thou there can kill a port job. Going to far would be one prime example....

Its just time and money. Im not talking down to you, its just ive been there and done it myself. After taking some lumps you start to learn certain things in life.

BTW, this is not the first time ive seen this happen with a Dasa head. Its actually the second but too many for my likings.

[trost66]

If it was from over porting I wish he would of just told me. Instead of lieing about it. I'm going to call him today and see what he has to say. I just don't like to be lied to espealy when you spend that kind of money. It is funny to because the first time he had the head he only had it for about 2 to 3 days. This time he had it for more than a week.

[MR.BIG]

What do they do if they overport it. Do they fill in it and report it?
Definately keep us posted I was going to use him but I think I will find someone else.

[trost66]

I called and talk to dan today. He said that was what happend. He said each head is has different thickness. He filled with apoxy and reported it. He said it will acually be better than before. He told me not to worry about the reliablity of the head. He said it would last a long time. He said every once in a while that will happen. He said he reported it and did some other things to it for nothing. He said that that head will be a very good head. Huge improvements. I'm just glad he didn't try to lie to me about the problem. I just called him and ask him what actually was the problem and he told me. I told him about last time I called and somebody told me it was the vavle seals. He really didn't say anything about that. I will get to ride it this weekend and I will let you guys know how it is.

[eganracing]

so did u ever test it yet?

[chad502ex]

this is what happens when a port is overported.

[chad502ex]

one more.

this shiznit suks

[honda350r]

glue it and run it !!

is that fuel? and what exactly happens?

[chad502ex]

that was a water leak when the port is overported near a factory casting air pocket. when the engine temperature comes up and beins to pressurize the coolant it squited into the intake ports from the water jackets arounf the intake port.

this ported on a head before the DRG

[h-bomb450R]

have u tested it yett?????

[chad502ex]

i have tested my porting and it was about 10% more efficient with cfm and velocity than the Pro level comparison i tested against.

dyno proven to at 55/36 with HRC cam. I'll hit 58/38 next week with another more aggressive camshaft. and all on stock bore/stroke so i'd say that my porting is working to get both torque and hp.

Trost, how do you like your motor? It seems on my setup the DASA porting added about a horse or two. I must say I am not happy when people that port heads sign the head. Had to cover it up with a temp sticker.

I ask the customer before I do that, but it has become more common for builders whom port sign the heads automatically. Why does this bother your, honestly?

[hemp450r]

chad i have read a lot of posts from you and they all seem to say the same thing "thats ok but mine is way better, i have dyno'ed and mine are 10% or 30% better" and yet you never seem to post your dyno graphs? whats up with that, you seem to have the opinion that you have never made a mistake? just a thought

:rolleyes:

if you had truely read 'a lot' of my postings, and are not just venting ignorance, then you should realize that many of my builds have already been exposed forward and backwards, inside and out, detailing the entire build process. ....and..... in the end of nearly every one are dyno test backing up any claim that is made.

Stay tuned cause you are about to be shocked even further.

YUP on this site you can check out my 06 DRG build. IT is just a sick 06 450r.. and in the post there are a few dyno graphs it hink the best we did was 54 and change. also we did a pipe shoot out on my bike between dasa and rossier.

And yes chad knows exactly what he is doing. that is why he has my 05 motor down at his house now and my ltr soon coming :D :D !

Mine too!

Actually it's because of chads' knowledgeable and comprehensive posts that lead me to have him work on my 450r. Which was the 1st DRG dyno'ed machine.And it's reliable because it's all HONDA minus porting and piston.

Tune in it will start soon.:D Mike

Can't wait to see both our bikes up and running with new parts....
YEAH:devil: :devil: :devil:

[chad502ex]

thanks for your support guys. I do appreciate it.

[xsr_racing28c]

First off, Chad is one of the most helpful and honest people you will ever meet on here. He has been there willing to help me out with anything I've needed concerning my motor, and has even went as far as to call me back after we talked about the build, just to make sure that I was totally satisfied with what we have had in mind.

Not many builders out there will sit on the phone with you for hours on end going over your build from top to bottom, and even go through and explain everything throughly just to be sure you know exactly what is going to happen.

Chad is a very helpful and kind person willing to lend a hand to anyone in need and for anyone to say that he's just coming on here and talking spack about other peoples products is way out of line, because I can honestly say I've never heard him talk down anyones product...He just states what he knows and that is his own stuff. He has done intense testing and knows what he is talking about, so please do some research before you say anything to degrade him or his company.

Sorry for rambling on, but it just bothers me when people can't see the good others are doing for everyone by simply sharing his knowledge.. heck isn't that what forums are for???

~Jay

[ricks450]

i dont even know chevy502ex are have i talked to him, and i can tell he knows what hes talking about. dude i have been around this a longtime. and if you know a little about this, you would know this to. theres not one person that knows everything. and alot of these questions people ask. you would have to test every product out there to answer. like which 12.0:1 piston is better. dude you would have to dyno everyone on the same set up. theres not many people that have done that. so dont hate the man because he has experianced a couple of things. learn from it. ;)

[chad502ex]

Again thats for everyones support- muchos gracious!

[Sheepless]

OK OK enough jibba jabba

Where is the dude who paid DASA to rape his wallet?

Was the issue ever really resolved? Ride report? For the love of God, plez tell me a dyno sheet?

[trost66]

I never put it on a dyno. It was a huge improvement. It felt like I gained about a gear dif. When riding on tracks that I have riddin before I was usually a gear taller than before. I was over jumping alot of things at the begining. I love it though. They might have raped my wallet but this is the wrong hobby not to spend money.
