Posted August 1, 201014 yr hi i have a 1988 yamaha yb100 deluxe it seems to go well through the gears but bogs down in 4th this is about when i change gear 1st to 2nd 10-15 mph 2nd to 3rd 25-30 mph 3rd to 4th 40-42 mph i wondered if that seems right to you im also wondering if it could be the baffle as the owner before me cut it down edit:it also stays at around 42-45 mph in 4th no faster edit: just took the bike out for a 40min run when i come back i notice it is idling high and revs are slowly increasing can anyone help?

August 6, 201014 yr Author sigh this bike is to much trouble right the revs only sky rocket when the idle screw is turned right in also when i am slowing down and change gear down the bike seems to bog down but after 2 or 1 second the revs are back there
