The pics should be self explanatory. What I think has happened is through either lack use of or just wear, the dials have seized. When I got it apart I put a drill on the drive and I could see it all spinning but just clicking where you can see the tip of the crewy. I poked a small screwdriver in-between each o...

Having just bought a white 1993 TTR 250 for a short commute to work (9miles each way) can someone please advise on the road tyres that I will require. The bike will not be used off road at all, criminal I know but it was a bargain and ideal for my daily short trip. Also any idea of its value? 1993 model, white...

Just been messing about with my Brothers new TTR, well happy with it, started on the button, but he wants a new pipe between the header and the silencer.. This one looks like it may give in when subject to a bit of green lane use, the silencer is a Laser Pro Duro, possibly not originally Destined for a TTR, b...

I've got my motor off and right now I'm replacing the valve seals, filters, starter/sprag, and timing chain/sprockets. Is there anything else this 15 year old engine might REALLY need that could cause fatal errors? The mileage is unknown but the top end looks brand new, valve springs are tight, the c...

I've been offered a 00 Raid at small money. The guy who is selling it said he got it as payment for some work.

Going for a trail ride tomorrow - first since last October!

Guys, Its the first time I am changing the chain and sprockets on the 4GY. I'm changing the gearing having read the posts on this forum. However, the front sprocket; is it a left or right hand thread? Ive knocked up the flange (insert own joke!) and the 30mm nut has to come off. The bike is in first gear...

Finished work yesterday and tried to start the bike to go home and it wouldn't. On the button it just made a small click (and with the bike in gear it didn't do this so I would think the button itself is fine), and I couldn't even kick the bike into life. In the end I bumped it and it bumped first time. When I go h...

I'm talking about the two bolts that secure the exhaust to the frame. The OEM bolt (with the horrible hex key head) is apparently 90109-082G0-00 but is marked as obsolete. So what are we suppose to use? The equivalent bolt on the WR250R 95024-10016-00 looks the same except with a normal hex head. Anyon...

Looks like the TTR is coming off the road earlier than expected, in the last couple of days I noticed a bit of oil under the bike, had time to get a proper look today. Looks like the base gasket has perished, not sure if it has been put on correctly as it is hanging out by the edge of the engine by a few mm. Looks l...
