I have a 91 bottom end and 90 top end. which jetting and needle setup should be used 90 or 91?

Do you recomend replacing jets every now and then or just clean them.?

I only clean jets. Of course change them out to change sizes, rarely. Take 'em out to inspect for debris, but don't think they can go bad or corrode. I suggest going with the richer of the two choices for jetting set-up. Then go off of plug color and running conditions. Better safe then sorry approach.

thanks for your reply hillclimb#42, I wasn't sure weather the jets wore out after a while or not.
