I have a 2002 39mm fcr carb from a KTM520exc.It has the tps hookup.Will I be able to use this carb on my trx450r and if so what about performance??I know the crf450r has a 40mm so I wonder if 39mm would be sufficient?Thanks
YES you will!!! I am using that same carb on my bike and it RIPS you have 2 options when it comes to the airbox. contact mark baldwin at www.baldwinmotorsports.com and tell him what you are doing, he has an adaptor to go to the stock airbox to the carb. Of you can you a 400ex airbox that fits perfectly. and just drill some holes on the side where the stock mounts go and you'll be ripping in no time.
