Hi Chaps, Can anybody tell me the purpose of the little bolt, located on the front nearside (Gear change side) corner of the cylinder head just under the cam cover?? The thread has gone on mine and there is an oil leak from it, Can i re-tap and put a larger bolt in or does it serve some special purpose?? I ha...

Are the threads for the mirrors a non standard size?? I tried to use one of my mates mirrors and it would not fit, I have seen Yamaha Adaptors on ebay, some are to convert from left hand to right hand thread and some are for 8mm-10mm, I am unsure which ones to get, but think it is the left hand thread ones as the...

Hi Does anybody know the paint colour or code for the frame for 2005 model? Just stripped everything for a good clean and have an overwhelming urge to touch frame up!! Nothing bad just a few scuff marks etc Many Thanks Steve

I'm talking about the two bolts that secure the exhaust to the frame. The OEM bolt (with the horrible hex key head) is apparently 90109-082G0-00 but is marked as obsolete. So what are we suppose to use? The equivalent bolt on the WR250R 95024-10016-00 looks the same except with a normal hex head. Anyon...

A customer reported a problem with the first of a batch of header pipes recently made up. It fouled the frame down tube and wouldn't tighten up against the gasket in the exhaust port. I took the rest of the batch back to the fabricators this morning and they couldn't find a problem as they fitted their jig...

Looks like the TTR is coming off the road earlier than expected, in the last couple of days I noticed a bit of oil under the bike, had time to get a proper look today. Looks like the base gasket has perished, not sure if it has been put on correctly as it is hanging out by the edge of the engine by a few mm. Looks l...

Hi everyone, There is some great reading material on here and I've read just about all the posts I could find for info regarding my particular issue but I've found nothing similar to my issues. I'll start with a little history. I've owned my 2000 TTR250 for around 7 years and had it in storage for the last...

Hi Guys OK got to 1993 OE not sure mileage as Im pretty sure the 660km on the speedo is wrong. When cold, if I stick the choke on and try to start the bike, it will fire up then die, now Ive found the way to start it is to keep choke off and twist the throttle a few times to pump some fuel in, do this half a dozen times...

We sometimes get asked by Raid owners about parts on their TTRs that may not be standard. Just found this pic to show what was on offer as extras. 1st pic is the front disc and fork guards. 2nd pic is a plastic rear disc guard. 3rd pic is the kickstart lever and mechanism. 4th pic is the oil cooler option. 5th...

My TTR is standard but i have a new FMF Powercore (with db killer) , it came with the bike. I'm thinking of fitting it and opening up the airbox and fitting jets to suit. Maybe i'll also get the short header pipe. I'll still run it in standard form for the next few months before deciding to do the mods. So,...

Hi all. I bought a new old stock TTR250 from a dealer in the UK back in 2007 and had it delivered to my home in Spain. I think it is a 2006 model year, maybe 2005. I rode the bike for 66 miles and changed the oil and filter and then put it on a lift stand in the garage where it has remained for the last 7 years. I di...

do you tighten the rear wheel nut up to its specified torque or use a small tool kit spanner to tightening it up in case you need to undo it on the lanes?

Hi all, new member here forum looks great! Got an issue with my TTR whereby it wont run correctly off idle.
