Decided to check and clean my clutch this evening , basically I wanted to check the state of the basket before buying a new clutch pack . I re installed the plates making sure that they all went back in the same order and just reversing the friction plates so that the wear on the tabs was on the over run side ,Then replaced the clutch cover and turned the engine over with the kill switch in the off position to check that everything cleared , All seemed fine so I started the engine and pulled the clutch lever in to check that everything worked and it went bang and stalled

, On removing everything I have two broken posts , unfortunately side by side .
On inspecting the damage to find out where I had screwed up I found the culprit , At some time in the bikes past a post had been broken off and had been replaced using a bolt through the rear of the clutch drum

It would seem that either whilst removing or replacing the spring on that post I must have either loosened or over tightened the broken post and when I pulled the clutch in with the engine running it hit the cover and demolished the post next to it
