RC8R - 2nd Throttle Error

Postby SuperHoon » Wed Dec 25, 2013 12:08 am

hey lads,

just picked up a '10 RC8R because i couldn't keep waiting for the 1290R.

dead stock, just a 41t rear sprocket for better wheelies. done 2400kms.

anyways, got an EFI error which was p0638 2nd throttle malfunction. i cleared the code and it came straight back.

Where should i start looking? can you just turn the 2nd throttles to 100% like on the SD and it will still be sweet?

JUST WANNA RIDE IT!!

thanks
