Since we’re running the slide restrictor to about 1/2 throttle, I believe a needle clip position would help quite a bit. Thoughts?

Nobody has any input on this?

Something is making a banging noise during launch and you can see the chain jumping around. The kids both said that it made noises when you got on and off the throttle. I think this is a symptom of the clutch needing broke in. Perhaps a lapping day is in order?

I believe the banging noise is/was due to an misaligned chain/sprockets.

How much slack should the chain have?
