I have a strange one here... I had my bike sitting for quite a while (years) and took it out a while ago. I cleaned out the carb, airbox, oils etc and put in a fresh plug. For some reason it is very difficult to start. It starts with choke full out, but dies immediately (2 secs). And dies even quicker if I try ap...

I disconnected my battery recently, and when I refitted it, the odometer mileage reading reset itself to zero - not the trip reading, but the total mileage for the bike. When I took the bike to my Yamaha dealer for it's annual mot test last week, he said there are quite a few batches of Yamaha speedo's...

My second thread started in a day; something of a record for me! So, I got my TTR out of the garage after not being out for a couple of months, to prep it for its MoT. She started first time and all looked well until I checked the back brake - Nothing. The pedle pressed all the way down but no braking on the back...

My seat is seriously slippery. When I'm two-up it's not long before the pillion has squashed my unmentionables into the tank. Does anyone know if a) There's a remedy product to make it more sticky? Or b) Someone males a cheap grippy seat cover for the TTR? I have an 05 UK model. Thanks all

Hi All, My TTR is rattling a lot more than I remember it doing at the end of last year. When riding at a reasonable pace (about 40mph) on a road (tarmac) and neither accelerating (under-load) nor decelerating (coasting) the top end has a distinct quite loud rattle that I don't recall it used to do. It's al...

I did a lot of searching and read a lot about uncorking the TTR250 with a lot of good information. The problem that I am running into are the specifics. I have a 1993-1994 TTR250 that I just got professionally painted black. It looks incredible! I'll post some pictures when I can. As I looked for all of th...

I'm fixing up my friend's 03 ttr 250 that has been stored outside for the last 3 years. The bike had previously ran good before being neglected, so he handed the bike over for a quick tune up and carb clean. When I disassembled the bike, I noticed a lot of dirt in the air boot along with some in the carb. ...

A quick and hopefully simple quetsion; I have seen plenty of choice of graphics sets availabile for the tank, mudgaurds etc. But I would like plain white stickers for above the headlight and side panels (i.e the number boards if it were a MX bike). What do you use for these? Thx, Nigel.

Hi, Just signed up and wanted to know where I can get a flywheel puller to fit an '03 TTR 250.

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.
