It has 40k on the bike. The guy I bought it from rejetted the carbs and put on a cheap set of individual air filters on it. When I got it, it ran alot better, but it would surge at any steady speed. It would accell without bogging, but the air filters would be wet with gas if I rode the bike hard.
I did a few thing to the bike.
Complete carbs overhaul. Oil change, replace spark plugs, chain and sprokets. The jets he had in the carbs were 138's. I installed the original 112.5's that came with the carb kits. The jets that he installed had rubber orings under them which from all the research I could find, they should have had brass washers. I test drove the bike with the 112.5 jets in and it wouldn't accell at all even when I goosed it on the center stand. I removed the carbs again and installed 122.5's I got from a friend and it still wouldn't idle right and would bog on accell. Maybe alittle better, but I couldn't ride it. I sprayed the carbs with WD40 and found that the intake boots were leaking. I repaced the boots and carb synced the carbs with the 122.5 jets in place and it ran better at idle but still would bog when I would try to ride the bike. I sprayed the carbs again with WD40 and found the throttle shaft seals were leaking. I ordered orings and jet washers from Motorcyclecarbs.com, and replaced the orings and installed the brass washers under the main jets, and left the 122.5 jets in the carbs. I synced the carbs and the idle is alot better, it still will hang at 2000 rpms sometimes but smoother. I goosed it standing still and it accells better, but when I go to ride it, It will bog down and hesitate.
Somethings I wonder about. The engine isn't noisy so is it safe to say the valves are adjusted ok? I haven't checked the timing, because I don't have a timing light for a motorcycle. I haven't checked the points, if it has points. According to my manual it does. The needle is the factory needle according to my manual. It is not adjustable with shims. When I rebuilt the carbs, they weren't real dirty. I just wanted to find out what jet was installed in the carbs. I haven't pulled the plugs out since I done alot of carb changes. Should I install a new set of plugs and go try to drive it to see what the mixture is on the cylinders? I am about to pull my hair out. Please help!!!!!
