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. Unfortunately, I've been having a string of bad luck, this includes me dropping and breaking my bike just 1 week after buying it. I managed to find the pointiest pokiest rock in the bush and then hig...

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.

Hi guys, just putting a new piston in and noticed it has and arrow on the top of it. Assuming looking at the different size molded indents and the valves that this arrow should point forwards (towards the front of the bike) but some quick clarification would be great. Thanks
