mx race motor build help

[rush racing]

alright im building my o5 trx for mx racing and wanted to get some advise to start wat do you guys think of hetrick racing port jobs and cams? my next question is how well do the sparks racing carbs run and have anyone heard of any bad thing bout the vortex mapping from tokyomods any help would be great

[Ty's400]

www.moto-xperts.com for your head work and cam. I'm sure the Sparks carbs are good but I would think you could find the same carb off the dirtbikes for a little less price. Just have to make sure you get the adaptor for your airbox/etc. The Tokyomods Vortex mapping is great from what I've heard. Don't think you could go wrong with that.

Ill have a ton of feedback for everyone once i get my DRG build back.Chads also taper boring my FCR 06 carb so well see what the end result is.I have a good feeling;) As far as port work there are a lot of good porters out there but just make sure your not getting a rush job.Give Chad a call.I did and i ll tell ya after talking to him i clearly made my decision..And someone with some info and a flow bench is a definate.As far as Tokyo Mods my buddie has the ignition set up from them on his Baldwin build and loves it but i dont know how necessary it is.I have the 06 with the green wire mod and am happy...

try to get the 06+ FCR carb. The FCR carbs are basically the best carbs for the bike. Chad from DRG is a great builder and a lot cheaper than a lot of other places. I called Baldwin and Chads build is gonna cost $2500-$3000 cheaper for the exact same setup. As for the vortex, never used and dont know anyone with it so no comment.

bloodmoney what kind of build are you doing that chads work is 2500-3000 cheaper, i have a full baldwin motor, head, cam, valves, port, piston and vortex ignition and all of that was only around 2200-2500 i think.

[GIXXER1KR]

Yeah fill me in because Chad has my motor and its not even that much total...Are u doing a turbo or something...

[bloodmoney23]

no i was just going to do stroker crank, piston, headwork and carb and full bottom end rebuild. baldwin gave me a quote at just under 6k. I just hung up the phone on them

[patrickj75]

buy an 07 crf FCR carb. instant difference over a stock 05 carb. Service Honda sells them for around $400.
