no longer using the TTR to commute to work bought a set of Michelin Ac10 tyres which i got fitted last week. Only because other forum members have said they suit the bike. pretty big change from the Kenda k761 dual sport tyre which i had front and rear. On the way to the bush it was pouring rain and i felt conf...

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. Anyway, I notice a slight difference in the numbers on the bearngs. Both are Koyo 63/28-3, but the left hand one also has SH sta...

Can anyone point me to a wiring diagram for a 93 Open Enduro. The Haynes manual does not cover the older bikes I think. I have no instruments on mine but would like to fit a neutral light as it only starts in neutral and I cannot figure out what connector provides the feed for this light. I have found the con...

I'm interested in what airbox mods and jetting you are running. I know this has been done before (read them all), looking for some advice, I'll probably answer my own questions by experimenting. But I'd like to know whats working for people before I hack into my new airbox. When I purchased my TTR abo...

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. Ten motorbikes and 3 project cars have meant my poor TTR has been repeatedly pushed to the back of the pile and into the corne...

I'm really starting to get to know my TTR after owning for 6 months, more like the previous owner who's abused her somewhat. Latest issue: front brakelight switch not working however it turns out this isn't a TTR switch or may be even a different master cylinder. Can anyone help identify - may be it's...

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.

When I drowned my bike a while back I wondered how larger (not that large) bits of organic matter got in the motor as they wouldn't have fitted through the air filter and the filter was almost 100% clean on the inside despite having a layer of mud about 10mm thick on the outside. The exhaust didn't go under...

I have been reading a lot of threads on the internet about TTR owners who removed the snorkel from the air box and installed twin air filters. I also read in new models such as my 2011 model you dont need to rejet carbs with exhaust upgrade. So, question is, will the bike run with more power if i remove the sn...
