07 CRF FCR Carb on a 06 TRX450ER

[Choreboy]

Has anybody done this swap??? If so I'm in need of some help in order to be ready to race this weekend. Any and all help would be apprecieated.

I am not sure, but i am pretty sure that they r pretty much the same carb.

Not at all. The 07 CRF FCR is a 41mm where the 06 TRX450ER FCR
is a 40mm. The 07 CRF also doesn't have the carb switch wires like the 06 TRX450ER FCR does.

Yeah the CRF carbs are alot different then the trx FCR's.. Acc pumps are different and the tps connections are a little different. Change the tps connections and your good to go!! Works alot better!
