there was recently a post about this... yes you can and people have put cr550 motors in 250r and 400es frames.. you can also go to sabertoothracing.com and get a 500 cylinder for a 250r bottom end

Now, when you say "Here is mine", I'm assuming you mean a CR500 motor?

How's the vibration? Any frame problems? More importantly, would you ever do another one?

I did a YZ426 in a 400ex some time back..and it broke the frame in more then one place.....

How you do it???

Buy a 250r frame (mine is 86) and you should get a 86 not any higher than 87 so that the swingarm bolt can go thru the back engine mount just like on the cr500r bike, make new brackets for the front and your done.

I have a ton of money in this but thats because of all the chrome, +8 swingarm, and the rest of the bling...

I would not sell it for the world.

Have mine running now for over 2 years and i have Zero problems with frame cracking or anything, but then again my frame has been gusseted properly.

can you list the places that need to be gusseted for me please. I will be home from Iraq the end of november and am planning on building one. I have a 86 250r frame and a 88 cr500. the how much of a weight difference did you see. can you also email me some closer pistures of your motor mounts and gusset locations and any other info that would be of use.

Like i said the pipe in the picture is a 250 pipe, so no no problems there, but i recieved the 500 drag pipe, cannot seem to find an inframe 500 pipe that will work so i had to go with drag pipe.

Gussets, dierwolf gusseted just a few areas but the main area he gusseted was inclosing the entire triangle section by the front motor mounts i guess beefing this area up also helped vibration i dont know, i just helped :)

other areas were the typical areas you gusset on the 250r frame, believe there are threads on this already.

you said that you have been running your 500r for two years. when you did the install did you have to modify the wingarm mount through themotr to get hte sproclkets to line up. Or do they line up. could the cr500 motor swap still beridden on a mx track or is it way to much for a track. Is a 500r just a drag bike.

And so will future projects!! Give it up guys there is a way better option for getting big power and the CR500 in a quad is not the ticket !!

ya well some of us are out to get the power for cheap. lots of people including me dont have the money for a brand new head from ESR. wish i did but i dont. im lookin for the cheapest power:cool:

hanzito

09-19-2005, 11:25 PM

Some of us can afford to do a ESR motor. But the CR500 is so much cheaper. I can get a complete motor for less than having my stock motor rebuilt. Plus it is something different. I just need to know if it is going to handle alot differently. So if someone who owns one or has ridden one can tell me if i would still be able to ride on a track with it or is it too much power. I am not concerned with the aded weight but i am concerned with how it changes the ballance of the bike.

Your right ,I bet in the end it is so much cheaper!

All the ones I have ever seen end up in the scrap pile ...

If your way of being different is throwing money away,so be it !

Just think of my post when you ride that viberating POS for the first time ! LOL

Have fun !!

The guy did not ask you if you would build one or your opinion on it. I personally don't care what you think. I'm sure that a professional like you has ACTUALLY ridden a cr 500 in a quad, right? Or are you just spreading another rumor that your buddy's cousin's best friend's uncle said about "his quad". Leave the guys alone and let them get the information he is looking for.

zedicus00

09-20-2005, 10:36 AM

if done decently it will be a great quad, cusion the motor mounts a lil and it wont break them, and if yur that worried get a wrist wrester and soft grips.

judging by how easy it is to build a cr500 quad i would guess back in the 80's honda had one on the drawing board before they canned the high performance quads, granted it prolly would hav had a counter ballance, its not really as big a deal as u guys make it out to b.

i do not personally know honda 350r, but if you go back to the 250r pic post forum, you will see him with a bunch of bad a** quads... i think he has been around some nice stuff... additionally, other members' (who i know know what they are talking about) responses to him posting again lead me to beleive that this guy actually does know what he is talking about. i personally have seen a lot of POS 500rs as well... "runs sometimes"... if you want a dragster, get a banshee... if you want a fast, reliable, rideable bike, get a 250r and put in a 265/275 kit and set it up right...

09-20-2005, 01:56 PM

I have ridden 3 cr500 atvs.
1. 87 cr500 in a stock 87 trx250r frame. it was solid mounted and frame was reinforced. everything was done sano. took the bike on one dune ride and never wanted to ride it again. lots of work was done to get rid of the vibration. great for hill shooting, but not for dunning, or mx.

2.88 cr500 in an aftermarket frame. rubber mounted engine, and longtravel suspension. much less vibration, but lots of broken engine mounts. It also cracked the frame multiple times.

both of the bike above had 15k to 20k invested and were cool as hell, but way too much trouble.

3. 86 cr500 mounted in an 85 atc250r. this was by far better then the two above. It vibrated much less. i think because of the three wheels on the ground, and was fast as ****. still vibrated alot for hard dune rides

Thanks 250r4life!!

Rawdeal is right on the money !! The ATC is a better machine to put one in.. I will still out run a 500 with a R engine though..!

09-21-2005, 12:32 PM

so zedicus00 what are you ridding???? if these 500 r's were so bad ***, then why are the 250r's still here? and where are all these 500 r's ??? afro enginearing is the key i guess, why not put an f-16 fighter jet engine in a quad?

zedicus00

09-21-2005, 02:32 PM

actually im getting ready to stick a cr500 in a 250R frame just to prove its not terrible...

as for afro engineering, well if thas yur thing mo power to u brotha....

i dont fly like that though, the f-16 engine would require modding the frame more then i would like.

cr500 can go in, and be taken back out at a latter time and hav a trx250r engine put back in, no frame mods required.

my uncle has a kx500 which i am assuming vibrates about equally. If that is so then yes they do vibrate really bad but that can be taken care of if done right. how are their motors mounted anyways? apparently people arent doing it right because they arent breaking motor mounts. if you used the same materials and are a good welder then i dont see why the mounts would break? i understand the frame is more rigid and such but not so much that it will always break. Dier wolf has one. ask him and he will tell you anything you need to know about doing it. Hope this helps :cool:

Somebody wrote that they wanted to do a cr500 motor to be different. If you really want to be different, figure out how to put a Honda Pilot motor in a quad and put a cr500 top end on it. Then you have electric start, reverse and no shifting. And it's counter balanced.

But if you must - 3k and you have this guys already done.

service honda sells cr250 powered 400 ex,s and they dont do rubber motor mounts, just gusseted in the right places and i have 2 friends that had this conversion just for dune rides one vibrated very bad and that one was sold the other one vibrated just a little not unridable the guy that put it together spent more time on it and hasnt had problems with it and still has it and loves it and talk about fast, that thing is alot of fun and with the aftermarket suspension on it, it handles awsome.

Honda350R knows his **** and anyone that talks **** about him I laugh at, aside from the fact that he is a cocky bastad(which he knows) and hes entitled to it. regardless if others thnk hes a cocky mo fo because honestly ,he don't give a rats arse.

I'll add this as well. Any R with a cr500 motor PLEASE come down to NJ and keep up with us on our less then 350cc R's . the point of this is to prove that you may keep up with us but your not gonna last 5 miles, the frame will crack and youll be stranded. well be going all day with no problem and our hands wont be numb. If you cant ride a bike comfortably as long as your body can keep up the stamina whats the use of riding it, youll just get tired of it.

09-26-2005, 09:09 AM

You are right people who have not ridden a cr500 in a quad or three wheeler dont understand. If you ride hard the cr500 in either machine will not last. For a drag bike no 250,265,300,or 330 will touch a cr500 built right on alky with NOS.
