Hi everyone,just bought a wr 400 (already regreting it) will a yz 426 carb fit with a few jet change..i mean a fewon my wr 400 and run better than the stock carb It has been redone this winter with Wiseco piston and has a lot of compression. Also there was a Yosh rs3 exhaust but i replace it with the stock silencer for less noise. I am searching for a yz 426 stock exhaust so if anybody has one left over in there shed...just let me know. Any advise is welcome. I have read a lot on yam carb mods but i am a bit confused. Right now stock carb is 168 mj,45 pj dont know about needle position. thank you
