Ive recently replaced the lower carb o-rings, seal and diaphragm and set up the carb with 50 pilot, I think 142 or 147 main (couldn't read clearly) with pilot screw 2 turns out, twin air filter (snorkel still present) and dominator end can. It starts up almost immediately but the popping on the overru...

Hi there, I just finished the 350 rebuild a few weeks ago and took it out for a spin for 15 miles and decided the jetting was too far out. I adjusted to 147 50 bottom clip starts fine, however the down pipe started glowing and therefore running lean. I checked my timing thinking it may be slightly off and i...

My 1995 model was running great when I did a 200 km ride 3 weeks ago, now it won’t start. I checked spark and compression to find only 65psi. Have checked carby and valve seating plus piston and rings but found nothing apparently wrong. Now out of ideas. ian, Australia

Hi. Can anyone recommend any folding mirrors for a 2005 Blue? There seems to be a lot of confusion about thread pitch, size and rotation. Thanks

Can anyone tell me what this part is please? I think it’s slowly leaking oil.

newbie here... Read through some of the posts and could not find the info needed. Looking for oil filter for a 93/94 TTR. What other model filters fit this model as cannot seem to easily source original filter using parts number. I was wondering if late model serrow 250 filters are the same. Thanks for...

Hi, Looking for a workshop manual for 93/94 TTR250. I checked some of posts here but they are dated, maybe cause its nearly 30 years old. I am aware that one can purchase one from this forum but the purchasing process is long and to much personal information just to purchase a manual. Does any one have one...

Bit more work done to my project ttr. Rear shock serviced and rebuilt and I fitted a grease nipple to the swinging arm.

Joss · Joss

Has anyone ever fitted grease nipple to the suspension linkage ? My xr600 has them and they make looking after the linkage so much easier .

This is a bit of a long story, but hopefully someone can see what I am missing…… Two years ago, I was given a 2006 TTR250 for use as an instructor at an off road school. It was a perfect bike spending 50+ hours a week teaching novices to ride - competent at everything and comfortable for my old bones! The bik...

My cam chain sounds like it's become loose (clattering, not as crisp as before). Is there a thread about checking the automatic tensioner? Can anyone advise me on this? Thanks

Tommy Young · Tommy Young

Evening, Has anyone used a different cage/support for their air filter. I have a 93 OE Not keen on spending the £50 for an original Yamaha one. I have seen some plastic cages on the internet but I'm not sure of these are for a Blue TTR? Anyone out there with a Open Enduro using a different cage?

Lancashirelad · Lancashirelad

Having fitted the 50mm lowering link I’ve come to the conclusion the stand now needs shortening, anyone who’s done this how much did you shorten it by, I’m thinking that as the bike had a tendency to lean quite a lot as standard maybe removing 25mm would suffice rather that 50mm, if I put some 25mm pieces...

wobbly · wobbly

A mot question, was wondering if anyone had come across. Fork seals are generally covered by rubber gaitors and hidden, to inspect them the tester would have to release the clip to do this. Never had an issue but never known a tester to do this, looks like the seals are overlooked
