It's been years since I rode off road and forgot, the lower limit for tyres running without tyre clamps, and typical pressures with clamps for trail riding using AC10's? Also with trail riding being on/off road, what sort of pressures do you use? I often ride out 30 miles to the trail meet, so is it a goo...

Finally had the engine sealed up today and got to fitting the clutch cable. and check the clutch. Holy Cow but it is stiff / heavy compared to my kxf250 and crf250x. The clutch has been changed at some point as the nuts had a few marks on them and the basket has very little wear.I am thinking someone has fit...

I had a question about fitting new friction plates and the easiset way to answer it was to do a pictorial guide. I had to plagiarise an existing guide and use library pics as I am not due to renew any clutch plates soon so it might be missing bits. I would welcome experienced owners to have a look at the guide...

I have a 05 ttr 250, it seems to be using far too much fuel hitting reserve at between 60 and 70 miles, it dies horribly at about 65mph in sixth gear as well, symptoms are very much like its running out of fuel at high speed although i think it may be a case of too much fuel is going into the cylinder. Other than...

Hi, The pictures below show the bolt that has broken. Has anybody seen this before and what is the best way to fix it? I was putting on my new disk that I just got from Brian and I snapped of the bolt. I have gave my torque wrench to my Dad and was to eager. Thank you, [IMG]https://i996.photobucket.com/alb...

I was thinking of trying to source a spare rear wheel with a view to having two different tyres available but with only requiring a rear wheel change.

Hi, I've seen some scary looking stuff posted on some other forums of LARGE bits of engine caught in sump screens which made me wonder if TTR even have one, in addition to the filter?

Had a search but can't find the answer. What size fuse should be in a Raid? It has 20A in the holder but the spare is a 15A? Also the afermarket headlamp wires have fused themselves together. If anyone has a yam raid headlamp for sale let me know. Cheers Spud.

My 93 TTR has always been able to start on the button whilst in gear. Then last week I decided as a bit of routine maintenance to spray wd40 in every electrical connector I could find.
