Front suspension

Smaller rear sprocket or Shift Kit to reduce engine rpm
Weighted handle bars
Swept back cruiser style handle bars
Balance engine

I think you hit the nail on the head, Ghost0. I would try things in this order:

Improve engine mounts
Smaller rear sprocket or Shift Kit to reduce engine rpm
Swept back cruiser style handle bars
Better grips
Weighted handle bars
Front suspension
Balance engine

Mount the engine with lead sheet. Fill the bars with lead shot.
Uh, don't run it so fast.

Have front suspension, crappy, but its there.
I have the corny grips that they all game with. Where can i get a different throttle grip?
I need the big sprocket for the hills lol
Weighted handle bars? How does this work exactly..
Balance engine... simple as it sounds?
Improve mounts, thats what i was figuring, how would i go about doing that?

Weighted bars- fill them with lead shot, or use bar end weights.
Balance the engine- yes if you know what you are doing......
I mount my engines with a sheet of thing lead between the mount and the bike frame, and also between the "C" clamp and the frame.

Balancing the engine? Just so its straight with the sprocket, and both clamps are completely touching (only happened perfect on this one bike) what else is there?

What we mean by balancing the engine is removing your crankshaft, rod and piston assembly and have it balanced. This is only for those that know what they are doing. This is the reason that your engine vibrates in the first place.

my bike vibrated like crazy. i did the engine porting, lowered the intake port and raised th exhaust port,as posted by here. this not only gives you more power but smoothed out the motor considerably. way less vibration, way more power.
