Why isn't there a kick start?

I wonder if the strange noise is a piston slap. My bikes have always started when I've killed the topend though.

How many miles has the bike done without a topend rebuild? Have you checked the 2T tank to see if it's empty? Also make sure the auto lube works if that's what you're using. Mine failed on a country lane at 60MPH. Will never use one again. Laughing

Compression has gone, you will have either broken rings, or a hole in the piston. Either way, sharp edges scraping up and down the cylinder wall is going destroy your engine,

Cylinder off, check it all out, replace damaged parts

Don't ride it until done else you'll just kill it!!!
