Been there, ....
Rubber blocks between the fins helps heaps, too.
See this thread: HT Engine Noise Reduction

Thanks, that thread was a big help. I don't have any extra rubber lying around but I did have an old foam handle bar grip that I cut up and used between the fins last night.

I'm going to test it out today. Hopefully the foam won't melt on me?

Are your rubber inserts strategically placed (other than on the outermost part of the fin so air can pass behind them)? I'm trying to decide if I should copy yours exactly, or if it matters too much. I don't have any dirt bike experience or anything to go by.

I used gasket material on the inside of my clutch case. To me it kind of seems like I mix between cardboard and rubber Of course it is more expensive than free cardboard but I'm hoping/thinking it should work. Plus it gives me the illusion that I'm using all "high quality" components..

I suspect that the foam will melt. Just try one piece first.
Natural rubber is best. (Pieces of a car radiator hose would work well.)
Regarding placement, it's not too important. I tried to put the rubbers where the fins extended the most and staggered them as much as possible.

you want to cure that whine noise from the clutch the EASY way?
Install a straightpipe with no muffler....the clutch noise will amazingly dissapear.

Actually it didn't melt, but I'm not sure how much of a difference there was sound wise. Maybe my engine is on the quiet side already?

Speaking of noise... Related to my bike being hard to push when clutch engaged... I have the clutch plate off to replace the gasket material with cardboard because the gasket material didn't make much of a difference muting the sound... and I think the 'clinking' sound that I hear as the engine turns is the gears.

I was watching the small and large gear rotate and what it almost seems like is what would happen if your sprocket was out of round: tight and then loose. I can't tell this visually but it feels like it when I push the bike. It feels like the gears tighten up and then loosen as they rotate around, and the clink sound comes as it loosens. Does that make any sense?

I am going to look into how to adjust the clutch. The bike still isn't firing right up. It takes a little while riding before it will idle at a stop too. Maybe the problem is in the clutch.
