Would this theoretical electrical issue mask a jetting issue? This is occurring in a specific RPM range? It almost sounds like there is a rev limiter when this occurs at 1/2 throttle. I am, wondering if this is happening now with the good flywheel I have on there now. What would cause the magnetic pickup strip on the flywheel to be all gouged up? Imbalanced crankshaft? Bad Woodruff key? etc?. I'm going back to popping off the mag cover and checking all electrical specs if my dipstick brother ever remembers to bring me the shop manual, and it stops raining :mad But what I am starting to suspect is electrical related, and what my main questions are? Returned all parts back to stock, jetting, reeds, everything, problem persists. ![]() Nice chocolate brown color on the idle circuit with a new plug. Bogs at 1/2 throttle, runs extremely rich. I go through a week of hell swapping for leaner jets, different needle positions, different reeds, different carburetor, SAME PROBLEM. Start her up week and a half later, now hesitates at half throttle again, still running rich. I fire her up again, Extremely loud backfire! Start her up again. Come back, shut er down, check plugs, plugs very dark. Like a raped ape! Still a little hesitation after 3/4 throttle. I look at reed cage metal reeds look a little fatigue, I throw in v force 3, and she takes off again considerably. I start with the carburetor, viton needle and float good and level. I have maybe ridden it 6-7 times since then, and noticed it sputtering rich and hesitating at ? 3/4 throttle, then starting doing it at 1/2 throttle. I replace the flywheel with my good one and and away she runs. I trace the problem to faulty eaten up magnetic pickup strip on flywheel. Last year I attempt to fire this motor up. ![]() Last July I threw this motor in after cleaning up cylinder and rings with a hone. It seems to bog at about 1/2 throttle, and sputters rich smoke. I have been having trouble keeping it running smoothly. My R that I ride, I swapped the original motor last year with a stock motor that I bought off ebay. I will show pics of mine when i get it off the ground just been playing with frame and plating last 2 years. hehe) There are some very nice restorations on here by the way. (Sorry been splitting cases plating bolts and powder coating frames. This is my first post on here in the 4 years that I have been a member of this forum.
