How long does the sprag clutch last before it goes bang and takes engine with it, my ttr has 6,300 miles roughly If i buy a kick start kit and undid the connections for the starter would that prolong the life of it. how reliably is a ttr for everyday use and whats typical mpg

Having just gotten my TTR, I am going through repairing the odds & ends that are damaged or broken, one of which was the headlight/plate. It had a broken tab on one side, presumably from a spill & was bouncing around pretty good when I got it. Instead of repairing the one tab, I decided to remove t...

My brother-in-law's (Keith) shock started to leak oil. We just pulled it out and cleaned it up and, sadly, the chrome is damaged on the shock shaft. Can anyone recommend from personal experience a reliable firm to regrind and rechrome it please? Alternatively has anyone got a shaft in good conditi...

Hey guys. Got the TTR running. Ripped on it today. May not have been such a great idea. It cranked and ran like a dream. Lots of fun. Then went to start it and got nothing. It sounds as if the starter motor is the only thing turning. It is making a ticking noise. Bike isn't really trying to turn over. Occa...

Hi all, Usually I only post to point out the obvious or ask really dumb questions but this time I thought I would share how my rebuild is going. Firstly I thought my bike has always done me proud so a while ago I treated it to one of the first batch of 350 kits. I was too eager to ride the bike so overlooked tart...

I just found this excellent video! The only criticisms I have are that (a) he forgot to put the solenoid earth strap on the rear starter motor bolt before fitting the oil line etc. and (b) forcing the carb in like that isn't good as it is quite likely to separate the rubber from the aluminium stub on the in...

Hey all,domski1 wrote. I know this is slightly off your thread topic but how about trying to to find the different models / colour schemes.

(See here if you are looking to replace your fork seals - http://www.ttr250.com/TTR_renew_fork_seals.htm ) If your fork seals are good but you are not sure of the age or quantity of oil in the forks, it is a relatively straightforward job to change it. First up after removing the forks from your TTR is...

Air cleaner servicing would be the worst job on a dirt bike, pretty dusty here in South Australia so I really need to keep on top of the air cleaner servicing. Lucky for me both the WRR & TTR take the same filter. I have tried many different brands but found the Twin Air to be the best for me. In the old da...

To try and take the guesswork out of which size cable clips go where on the frame, I decided to be more methodical on the last dismantlement of a metal-tanked OE. Raids and blue TTRs might be slightly different - but I don't think they are! I took off 11 clips and they are four different sizes: four 6mm, one...

In a winter time while my bike was sleeping I decided to fix a rear shock. Sometimes fixing can make things worse. But this time I succeeded. The shock was leaking the oil a little bit.

With the current interest in big bore kits that require the crankcases to be stripped for boring to take oversize sleeves I thought this would be a good time to create a pictorial guide to include a full strip down and rebuild.
