Tuned and Synch'ed
I think my 94 Cali (carbureted ) is in good tune, the plugs are picture text book perfect. After I warm the bike up if I flog it in 4th especially 5th gear,after I have reached 4000rpm the clutch can slip and over rev. Now if I ride it like a sane human, I don’t seem to have that condition.
Now here is my problem and frustration. After the bike is warmed up, running it through 1st, 2nd and 3rd gears at a an easy acceleration rate up to 35-4000rpm that is its happy spot, the engine is spinning and bike is running smoothly like it had an electric motor My speed is roughly a little over 40 mph. Now when I grab 4th and bring it up to rev, the engine is thumping a little and will not completely smooth out and my speed in crease is about 15-20mph faster, go for 5th gear and bring it up to the happy spot and it is a thumping monster, calms down somewhat and my speed is around 65 mph. I know that it is said that the 5th gear is too tall for this model but the engine is at 35-4000 rpm and should it be running smooth like in 3rd gear? Should the engine be spinning instead of thumping? I hear the carbs sucking hard through the air box in time with the cylinder fire. Not enough air ,too much air, not enough fuel, too much fuel? Or could it be a failing clutch. My mpg is a steady 32.
Maybe my fly wheel needs to be balanced, I don’t know. Any insight and comments appreciated.
