So my buddy has a 04 crf450 and blew it up. He said he will sell me the carb for cheap and if I'm correct the fcr will fit on my 05 with the adapter. my question is, is the CRF carb big enough for the trx I belive they are 40mm? (i don't see why it wouldn't be) and from the looks I might not have to mold my tank with this one because it looks like it doesn't go as high as the ones from the 06+ trx. Is there anything else im missing? Because I cant pass up the price he wants for it. Its beyond robbery he knows what its worht but wants it gone lol and ive been on him to sell it.
