new build shudders when clutch is released - headed to salt flats!

Just went for the first spin on my new build. This is actually the second crack at the first build. The original was an attempt in a frame that simply had difficult geometry to work with.

That said, bike starts and runs and works decently under pedal power. However as the clutch is released the bike begins to shudder/buck and continues to feel that way after the full release.

The initial build in the old frame did not feel this way.

Any tips would be great. Want to take it as a pit bike to the BUB Speed Trials this weekend in Utah.

Yeah I think you might be right. I was feeling a little paranoid about the chain binding or not tracking well and was probably a bit too cautious. Fooled around on it a bit later and feel better about it.

Headed to the salt on Sat to support friends who have built some wild motorcycles. I'll be 'representing' with my bike!

I'll post some pics soon.
