Who does the best port job for the 450r?

[czrider263]

I just took apart my whole motor and decided while it was apart to get some work done to it. Im going to put in a piston(don't know what brand) a port and polih and cam. i already have a pipe and some other small things. Im looking for a sick mx motor. WHO does the best port and cam match for this?????

[hardkoratvmxr]

i think curtis sparks imo

[mikes450r]

check out boones450r he does some really nice work..some of the best that i have seen and he has very fast turn around time..

I don't there is just one answer to that. There are alot of guy's out there doing good head work. Everyone has there opinion's. As for Curtis Sparks, good luck getting your head done by him in the next year or so..

TC Racing builds good MX motor's
Mark Baldwin also builds a good MX motor, he did my port/valve job with his MX cam and piston and I'm very happy with it. I've ridden many other 450's and it makes my like mine even more.

boones450r definatly

well, just like i've said in the past, Boone's work is the best i've seen in pictures.

The only question I have is:
I know he has done a few port/flow jobs, but has he ever tested the cfm throughput of his work (before and after)?

work look'n good and performing good is two different things. Don't get me wrong, i think his work performs really good, but i prefer test data.
just wondering if he has tested that's all...

Dan Lamey at DASA for sure. Knows a ton about port/flow work and has a lot of time on the bench. Hes the one who developed/invented all the TREX stuff for banshees and they all put out huge #s.

[czrider263]

is there any pics of his work? and how long will it take? and how much will it $? from this boones 450 guy

Curtis Sparks by far :macho

[mikes450r]

ya sparks will be far and away before you ever get it done..

do you think he wants to wait a year to get his head done..i dont think so..

John at Nmotion does exceptional work. He built my motor and dynoed it at 53.2 hp. It has a cam, springs, je piston, +1 valves, and crf ignition and flywheel, fcr carb off 04 crf450. He is very knowledgable and has won pikes peak 4 times. Also the guy at dasa does impressive work and alot of r@d. Either man I would trust with my motor. Also I would allow Baldwin to do my motor as he has experience with factory team honda and does a simlar job to what Tim farr has done to his rocket.

JH Racing has done extensive work on the TRX motor and has done some great port work. He's getting my motor soon. The motors he are building absolutely scream. Turn-around time is quick and is somewhat cheaper than maybe Dasa, Sparks or TC I'd bet.....

Sparks does AWESOME work but you'll wait for a LONG, LONG time on your motor and its just not worth it.......

[Jersey450R]

Dont forget about TC Motors.

[stonerider250x]

dont leave out HetRick Racing either ;)

Ya JH Racing did my port work took like 3 days turn around time.
He is the only person I let do work on my bike other than myself. I just trust him. I drove all the way to his shop to meet him and he is a total stand up guy!!

[Steve-O]

Take it too kevin @ Lost creek cycles right there in PA . TC racing does all their motor work and his customer service is top notch!

[Dave400ex]

Don't forget about GT Thunder either. I would be sending mine to either TC Racing, Baldwin, or GT Thunder...

He had one of my heads done in less than 1 week! I like his work. He's fast, he's reasonably priced, and overall, i just like the dude. Met him here online and i think he is a stand up guy. Go give him a try ;)

Boone does AWESOME WORK!

You guys want some cutting edg stuff don, then go to Joe at Rossier Engineering. He has a Dyno, Flow Bench, and a ton of experience. He is doing things that no one else is even thinking of. He will get you in the 51-52 horsepower range for cheap, and it will last. Not to mention, he has the best pipe on the market. You can go as mild as polish work, and as extensive as full port polish, milled down head, taper bored carb, etc. He is the man, Call 715.341.9919. Tell him Josh from Oklahoma sent you.

[czrider263]

yeah i like rossier i have one of his pipes. its not too loud and has a ton of power. do u think a port and polish form him would match nice? how long and how much does it cost? theres nothing on the rossier site about 450 porting.

[TRXDresh]

I am getting mine back tommorow. I have yet to get a price yet. Your gain is going to depend on how much stuff you do. You get his piston with his port work, and you better hold on for dear life! He gets it back in 3-4 weeks. He will also spend time helping you get set up. Let me know if you have any other questions. Some of the great things about Joe is that he is a smaller operation, he does all his stuff himself (Meaning he doesn't just assemble it after someone else ports it), he has a flow bench and a dyno, and he is an engineering genius.

The guy in all black next to Natalie does great work. It's Dee Manshack out of Cleveland, TX. He is Natalie's mechanic this season. His company is Rage ATV and the number is 281-593-2481. All of his stuff is flow bench tested. He knows the 450R motors real well as well as a lot about aerodynamics.

He did head work on both the 450R's pulling a big holeshot in this pic.

curtis sparks is doing john natalie's motors

[bobbo97f150]

I never said he was doing Natalie's motors, I just said he was his mechanic. You are correct though I believe, Sparks builds Natalie's motors.

[TURBO-530R]

looks to me like the dude just left early. hehe

[Salinas]

Ya i gotta say Dee from Rage atv is top notch all his motor are always front runners in holeshots .He has built 2 motors for me & i wouldn't have anyone else build my motor .

Scott Cain Racing is our local guy. I had him clean up the ports on my XC head and few other tricks. Very pleased. I know he does MX motors and they're all tested on the flow bench and all that good stuff. He knows what it takes to build a good performing motor.

[scotturban]

my vote.: motoxperts in laffeyette indiana

Builds casey martin and aaron meyers pro am quads, bill ballances yamaha,

look how many holeshots there hondas have pulled this year in pro am production mx class. all but a few

[jjm400ex]

Racers edge for sure. they do awsome work and have the best customer service and turn around

[trompen542]

SWP in Michigan, he does all of our teams work, he has a flow bench, and a dyno to fine tune. the bikes are very fast, and reliable.
ask for jake
