Hello, my first post here but i've been lurking for a couple of weeks. I'm in the UK and have just bought myself a 2000 DRZ 400 E. It is road legal (just!) and has been great fun, right up until yesterday. It suddenly appeared to stall as i was slowing to a stop and then wouldn't start. It still turns over smoothly but will give a nasty backfire occassionally as I try to start it. A friend of mine came round and checked the timing... it was out by 1 tooth. He reset it all and tried to restart the bike but it jumped a tooth again as it tried to start. From what i've read and from what happened, i'm thinking the cam chain tensioner has either failed or is backin off just enough to allow the chain to jump. Would this be about right? I'm struggling to find a manual cam chain tensioner here in the UK. Even Ebay has none! I've seen the tensioner in the TT store. They'll deliver to the UK ok wont they? Help!
