I have run out of good s/h exhaust valves. I have half a dozen that are pitted to one degree or another that I am not prepared to use.New valves are relatively expensive which makes me wonder about re-facing the valves I have.It is possible to buy kits to do this on eBay but only for older "soft"...

I have a '04 TTR 250 and it seems to be screaming at 100kph? When I got it 18 months ago that wasn't the case. Dad has a '00 TTR 250 and it can sit on 100 fine? both bikes have the same sprocket sizes, and basic mods were done to them and I was just curious as to what you guys think the problem could be? This bike has...

I have recently rebuilt a standard 250 TTR engine and need to test it out. The only TTR left in my garage now is the 325 so my aim today was to whip out the 325 engine and replace it with the shiny "new" 250 rebuild. It was interesting that, despite torquing up the engine bolts when I fitted the 325 engine seve...

G'day, I have a 2010 (Australian) TTR250 that has about 600kms (370mls) on it. The bike has only been ridden very lightly and is almost as new. The bike started first go after a four month lay off but would bog down as soon as any throttle was applied. I suspected the fuel may have gone off so I drained th...

Hi You Knowledgeable Lot! I'm wondering if anyone can tell me what the name of the seal in this picture is?

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!

Currently rebuilding an engine and the main bearings are a bit "lumpy". Surfaces have gone grey and there are marks where it looks like swarf has been crushed into the surface.

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. When I went to restart the bike, all it did was turn over but wouldn't catch. Upon pulling the choke out, it would fire up, but die as soon a...

It's been over a year since I last posted, I think, but I've been busy in that time, I've acquired more motorbikes, been building a Jimny into an off-roader and assorted projects.
