After changing the ferris wheel I went 1000km. but i had a problem with the engine broke the distributor without serious consequences. I replaced the exhaust camshaft, timing chain and chain tensioner. I assembled the bike and everything was fine. I started to make friends and I felt the clutch slip as the 6th gear began to slip. And the engine power was noticeably higher than before. Before I bought it from the previous owner, it was replaced by a timing chain, but they did not engage it properly, there was a two-tooth grinding.
