My 1966 305 scrambler has been running great since rebuilding the engine last winter, but I had the bike parked in a loose gravel drive way on it's kick stand and it fell over on it's left side. I doing so the clutch lever was pulled back and snapped the metal off at the pivot pin. No problem I had ...

I just got back to working on the engine following a long cold spell. I did check the shift spindle and it looks fine. Shifted the trans through all of its gears and it sure appears to be working properly. Unless anyone has a another sugestion, I guess I will put everything back together and maybe g...

Mike, I checked the number of shaft rotations in each gear position and the results seem to match G-Man's chart information, but I will check that shift spindle tomorrow. G-Man, that makes sense about the tire size, I guess if nothing else comes to light on this I can put a smaller sprocket on the r...

Mike, I don't know what I had for RPM's but at 50 MPH the engine was screaming. I have the engine apart now. Found the piston skirts pretty scuffed up. One thing that I did that probably has made this worst is that when I changed out the tires I could not find the original size rear and installed a ...

How small of a rear sprocket can you go down? G-Man, According to you graph my gear sets are right. I just c...

My 305 scrambler 1967 goes down the road fine at speeds 35 to 40 MPH. When I go up to 45 to 50 MPH in 4th gear the engine is revved up at such high rpms that it feels like the engine is going to fly apart. I thought for a long time that the trans was not shifting into 4th gear but I know now that it...

I just tried a 17 tooth sprocket I picked up on ebay. It fit the shallow spline just right however the tips of the teeth on the sprocket will not clear the kick starter shaft. Also the larger diameter of the 17 tooth sprocket jams the chain into the engine casting. I guess I will try and locate a 16...
