Well I finally got round to having a look at my 2000 te610 after it laid dead at the back of the workshop for 6 months. It died on me while I was out riding and just gave up on it as I had other things to sort out. I decided to get all the parts together to do a cam chain swap and go from there. Pulled the bike apart and pulled both side cases off. Found out why it stopped, One magnet had detached from the rotor and broke in half. Lucky I had a spare engine for my bike so pulled out the rotor ready to use. got the bike setup and did the cam chain following the book and numerous online pictures and the timing was set spot on. I fastened everything up and tried the bike and it spun over great with out spark plug. put the spark plug in and it turned over and it wound over twice and stopped dead. F*****K . tried it again and it spun a few times and stopped. Decided to check valve clearance and was 0.002" so thought battery was a little low so put the battery on charge. also decided to make new battery cables as the ends looked a mess. I pulled the clutch case off again and set the engine to check timing and it was on the money. built it back up enough so i could try to turn it over (left pump cover off). tried it with a freshly charged battery and no spark plug and it spun over. put spark plug in and it turned over and stopped dead. I can't make heads or tails of it as it makes no sense at all. Any ideas???
No need to worry, I got it sorted. I stripped it down once more and reset everything. built it back up and it fired up no problem. the cam chain i used on the bike was for a honda cbr900. it was 126 links long so shorted it and used a new link. job sorted
