crf setup

[AAracing]

Ok, I know about the head swap and what not, but how about the crf head with a crf crab? is there any reason to run the bike carb compared to the quad carb with the crf head? if i remember right, both have the FCR carb, but not sure if they are the same bore and whatnot. i know its a big hit on the 04-05 motors to run the bike carb. as far as setup right now, i'm running a Sparks head, with 15.1 piston, titanium 4 FMF silencer with an HRC head pipe, fan is hooked up to a toggle, and using the HRC Cam now. great set up the way it is, but any little bit helps to run with the big boys

the crf carb and trx carb are basically the same, the bore sizes are different between some years on the crf's but you would be better off sending your carb out and having it bored
