I have been offered a purple early TTR250 with 30,000 miles on it, that has had a rebore/new piston and rings and a top end refresh recently (bills to prove all work) So are these bikes good for a high mileage? Chassis looks in excellent nick, so does wheel and forks What sort of price should I pay for a 1993...

This is quite a common problem on TTRs and I have come across some ingenious repairs! The blue headlight surrounds are hard to come by second hand so it is worth repairing them. I apologise in advance for the poor quality of the pics. I think I had the flash suppressed I carry a fairly heavy Slime compre...

I am frequently asked about what after-market exhaust is best for the TTR. The requirement seems to be that it is light, reasonably quiet and sensibly priced. The problem is that I can't find anyone in the UK selling such exhausts. Has anyone else found one they can recommend?There seems to be a gap in t...

Bought a TTR recently and although the previous owner said the sprag was OK, it seemed to be making some noises when operating the starter which were extra to the usual bang on switch off Stripped it down today and found one of the most damaged sprags I have seen so far so it goes in my Black Museum!

Looking at the parts diagram there seem to be 2 chain wear guides. The big black one at the front 4GY-22151-00 and a small white at rear 3JD-22147-00 Are these the only wear guides and can someone verify the numbers for me. Also on the rear shock there is a rubber bump stop or something like that but I can'...

On a recent outing all went well until I tried to restart my TTR 250. The first thing I did was replace the plug as it was turning over OK.

HI I am experiencing some fuelling problems on my 02 ttr250r. What happens is when going at about 100kms pr for a couple of km the bike runs out of fuel in the carb, slows down and stops for a half min or so and it will fire up and run again. It does not do this at lower speeds. The same happens when pulling up...

Unlike the originals, the after-market shims are in intervals of .005mm or is that 0.05…. but that is usually sufficient to get the clearance within specification.The TTR shims are 9.48mm in diameter and these guys do them for £2.85 each inc. p&p - http://cgi.ebay.co.uk/VALVE-SHIMS-CRF-R...
