So I went to change my oil today and when I went to drain my oil and there was only a few drops of oil That came out. Filled it up and cranked it up and it is running good no unusual noises. I rode it around and it ran fine. Pulled back to the house and it was squirting oil from the base of the cylinder. Found a kit to...

Hi You Knowledgeable Lot! I'm wondering if anyone can tell me what the name of the seal in this picture is? Then I'll ask Brian if he has it in stock :) It looks easy enough to replace once I get the tank off; am I wrong? I think this has occurred because I feed my 19mm chain between the engine and the frame (sma...

For the best part of a year now my bike has been vibrating a hell of a lot, jerking into first, and jerking when going down gears and just being extremely rough. It was extremely disappointing and for the life of me i could not fix the problem. I changed the sprockets, chain, went over the bugger so many tim...

Just bought '55 plate (pics in new joiners) and I noticed the h/l bulb was gone when I picked it up so the garage fitted a new one. Now I notice that has gone already, after just ~100 miles. Any faults I should look for or are they a bit prone to going? All other electrics work fine. Thanks

I had a bit of a sort out of my stock of used swingarms yesterday and it is probably worth posting another bit of strong advice to save owners money and time down the line. Check your chain slider - green plastic part that fits over the end of the swingarm near the front sprocket. It wears underneath so migh...

Like a lot of people, I am a sucker for the kits that Aldi and Lidl offer. I bought a kit that included what should be a very useful wire brush but, within a few minutes, it shed all of its wires! Is there a make or brand of accessories that might last a bit longer please? Brian

So I took my £800 1993 ttr of indeterminate mileage out for a 60 ish mile run including green lanes and 60mph b roads last sunday.

Hey, Should my bike start in any gear with the clutch engaged? I can only get the electric start to work if the bike is in neutral? Just wondered if this was the case with these bikes? Thanks PS. see pic for a very overgrown lane that I fell off in yesterday! The brambles hurt!

Hello ttr250 community I recently picked up a 2003 ttr-250 and finally took it for the first rip last night. I was having a blast until I downshifted and the bike died.

Can anyone please confirm whether there are any issues ie clearance with the fork boots with the above tyre size (it is a Dunlop Geomax AT81). Apparently the 80/100-21 is not overly common and there is some doubt that it is actually narrower when mounted.
