Hi all, new to the CRF world. Just bought a '07 CRF250R for my son and wow what a difference from what I am used to from the 90s. We bought it knowing there were issues starting, but once started it would run great. The bike sat for a while so I figured it would be a carb rebuild and cleaning to take care of it.
Ordered an All Balls rebuild kit for a 2007 CRF250R, received the parts and there are a few difference from the carb to the kit, one being the needle is a different length. Looking more at the carb and the manual, it looks like they went from an FCR01C in '06 to an FCR01D in '07. The carb on the bike is stamped with FCR O1CATH22.
Does anyone know if that means this carb is from an '06 and not the original '07 carb? Is this a valid swap, it looks like the jets and needles are different between the years in the manuals as well?
Anyone know how to order the correct rebuild kit based on the carb identification number?
Can you rebuild the different version of the FCR with the different needles / jets, etc to match the stock settings?
Any advice would be greatly appreciated
