Thanks for looking; I have a 1978 KZ650 with the VM24 carbs, no jetting, no pods, and no exhaust completely stock. The bike has new oil, properly gapped spark plugs, clean filter, leak free at carb holders/intake boots. The carbs are clean and rebuilt, by first myself then by a professional. I couldn’t get the bike to idle properly without having high,low idling and issues dying, and is now doing the same for the mech. I am certain the carbs are not the problem and am ruling them out for now. What other areas can cause poor idling?
So far with my research I have turned up a couple areas that I have not perused. Petcock- my current one work as supposed to, with gas tank off and in the prime position dumps fuel, in the on and prime Pos does nothing. There is however a small leak in the petecock, but I don’t see this as big issue. I plan to upgrade to a vacuum 6000 series Pingel (6211-CH with adapter) to fix the small leak. Points ignition- I have read about frozen advances, take off the points cover and spray WD-40 or replace with Dyna S. Lastly the gas cap which has holes to allow production of vacuum from air being pulled through the system. That’s all I got, as frusterated as I am I can only laugh and makes me more motivated and hopefully more rewarded when I stop letting this old Kaw get the best of me. Any suggestions are welcomed and I apologize for the long post. I just wanted to supply those willing to help with as much needed ammo as possible, thanks again.
