We built a grasstrack bike in the late fifties using a 250cc JAP motor from (I think) a Cotton. I fell off it at Barham and it didn't arf hurt. Crying or Very sad

Fly,

I have found a picture of a 1927 Cotton TT with a twin port 500 J.A.P engine. If it's of interest let me know and I'll scan it.

Hi Fly, I found this photo of a later 1938 JAP engined Cotton. I think apart from the engine they did not make any major changes.

Good Luck, Nic
