This is my first post, so go easy on me if I do something wrong. I have a 1999 TTR250 that I have yet to see run correctly. When my dad bought it, the throttle assembly was stuck, carb was completely gunked up, brakes were shot, wouldn't get gas through to the carb, and every part that was possible to rust, w...

Does anyone happen to know what the output is from the generator (blue tank model if it makes any difference)? Got the wife a heated jacket for Xmas and wondered if the TTR could power it so she can commute on it instead if her BMW which I have in many pieces at present! It pulls 77W apparently. Simon

Hi, There are many kinds of FMF PowerCore 4 exhaust systems, and I am confused as to which one would be the best fit for my 1996 TTR 250. It would be great if you could provide me with an exact reference number or part number. The prices range from $150 to $250 but they all look the same to me! Thank you for your...

as the title suggests, im interested in knowing what size tubes people carry if they are going for an adventure. i have a 19 inch tube, so it can stretch into the front, or sqeeze into the rear in an emergency. obviously i wouldnt keep it in there I would change it when i could. what do you guys do?

Every time I go out for a ride, when back home I have to physically take the side panel off and take air box cover off and drain loads of water out, I thought it had a draining system? I noticed a gap between the seat and mudguard and can see where water gets in, I can't understand why the snorkel faces toward...

Hey guys, I have a ttr-250 and have noticed that my fuel tank has a crack in the top of it after it started leaking when I filled her up. The crack is about 7cm long I would say but it's only a little hairline crack. I have tried the solder iron trick but I can still see the crack, I'm not even sure if this theory w...

I am on bearing refurb duties today. Just stripped out an old link arm and was a bit surprised at how worn the lower shock bearing was. The outer bearing case was worn through and the bearing had taken a substantial groove out of the link arm itself which is sadly now scrap I don't think it would have passe...

I have a 1998 OE that seems to have a strange electrical problem that I could do with some help on if possible. My bike generally starts with no problem, but when running the bike often 'cuts out' very very briefly and then continues to run. It almost feels like someone has turned the key on and off very qui...

Hi everybody, I am the new owner of a Yamaha TTR250 2006 model, and as such I am a new member to this forum.

Hi all, after a bit of thinking, iv'e decided that my 2004 TTR250 is in need of a bash plate. yes i could go and buy one, but as a boilermaker, i can do it myself, and at $100+ i dont think its a really fair deal! anyway, would anyone have a template or something that could help me out with making a template? c...

I know it's a common issue, the wearing of the front brake hose where it rubs on the guides. I was wondering if replacing the front hose with a metal braided one would resolve the issue? I know the HEL or Venhill ones are still plastic coated over the braid, so I guess this might still wear through, but on...

Hi Guys, So about to go out to get new oil for my rebuilt motor (have some Penrite Semi Synthetic 15w-50 that says on the bottle it may be used in engines that require 15w-40, 20w-40 & 20w-50 as well as four stroke motorcycles that have wet clutches), my question is should I use this or get something mi...

Hello people. I was going to adjust the chain on my newly bought 2003 TTR but thought that it may in fact be worn beyond repair. I measured the 10 link distance as recommended in the manual, which suggest a wear limit of 150.1mm. It was pretty much 151mm. But then I read that someone elsewhere (I can't reme...

I'm looking for a 2nd rim so I can always have two sets of tires ready to roll (one for mud and one for rocks). There are very few used TTR rims available on ebay because it's such a rare bike. Is the TTR rim interchangeable with any other bike rim, like a YZ?

Hi chaps. wondering if there is a reason you recommend replacing the top bearing with a different type?

On my last ride the bike sounded a little more 'grindy' than usual when starting up. I figured my sprag clutch was failing as it's been clunking a little louder, but when I pulled the cover I found the starter shaft is missing a few teeth. The idler gear is missing one too. The sprag clutch spins freely an...

Hey guys. I acquired my 03 TTR 5 years ago from a friend who bought it new, but hardly ever rode, cleaned, or maintained it. I ride it hard, and always do a good job of changing the oil and filter, cleaning the air filter, and I clean my carb about once per year. But the bike has never had any major maintenance...
