So summer has been spent getting drunk and eating BBQ food, the flooding in Glos was a good test for the C90, unfortunately, it failed badly... I suspect that the oil leak has upset the engine quite considerably. Praise be to whoever invented eBay as I have managed to aquire a 2nd hand motor for the beast. It'll be stripped down, bored out to accept a 125cc piston then re-assembled ready for racing.
Photos and update to come.
