A forum for owners of Yamaha TTR250 trail and enduro bikes!

I happened to use the TTR to commute to work early one morning (about 5 am--dark) last week and I noticed that the header pipe got a pretty bright red while warming up with the choke on. After easing off the choke and riding the bike with normal throttle, I leaned over and saw that the exhaust header conti...

Hi all, I'm new to the forum - I've got a 2002 TTR250 which has developed a bit of a cold starting problem. Essentially, I usually turn the fuel on, choke out, then use the electric start and it fires up after a couple of seconds holding the button. Recently though, it just turns over and will not fire up f...

I am busy reading the repairs thread - finished the carb one earlier. I have an odd issue. It only happens in 6th gear, usually while overtaking a car. I will be going strong, when all of a sudden I get a splutter in the revs, almost like running out of fuel. When I change to 5th, I can rev strongly with no h...

The Missus just passed her competency test for pre learners (Tasmania) and is keen to start riding the TTR to work so i was wondering if anyone knew how to lock up the tank for some added security, more concerened about vandals and skanky additives than pilfered fuel. Fuel is easy to replace. Probably...

On my way to meet up with some mates for a trail ride earlier in the week, there was a death rattle coming from the 325 that prompted me to turn around and head back about 3 miles from home. Really disappointing as I don't get out much these days and the ride was in the Dawlish area and haven't ridden those lan...

Hi all, First off, a quick introduction. I’m Ollie, and I’ve had my TTR for a while now (a year or 18 months, can’t remember exactly). It’s a K reg metal tank version. I use it for green laning so it gets a bit battered and bruised, but I always give it a lot of TLC after each trip! There’s one slightly odd f...

The old beach ridden bars replaced by a resprayed set. Only major job the beast has had its entire life is a camchain. Uses no oil , just a couple of puffs of smoke on start up after sitting for a week.

Sorry about the bad pun but I have spent a few hours this afternoon trying to sort out a TTR250 front brake master cylinder and it's sort of making me feel a bit hysterical My mate Jim has a collection of shiny chromed up vintage(ish) Jap bikes and spends quite a bit of time fettling them and trying variou...

I'm taking my forks apart because one of the stanchions is bent from a bad fall I had in Portugal. I need a special tool to take it apart and although it's possible to do it without, I prefer to know it's done properly when I put it back together. I have an alternative reason here for wanting a tool, I recentl...

My TTR250 stock exhaust has a distinct bend/kink where the stainless trim covered pipe section joins the main body of the exhaust. Are they meant to be like this or are they supposed to be straight? -- Edited by Benjah on Thursday 21st of September 2017 01:03:57 AM

Anyone got any tips for when I eventually take this lot off and renew it all. It is rusty as well, i'm expecting the nuts to jut crumble when any force is applied. I'll probably use a nut splitter to get them off. Main worry is the studs snapping off in the head. Been spraying with wd40 everyday so hopefully...

Hi all My bike's PO told me to drain the valve on the oil breather line regularly.

If this was a water cooled engine I would be crapping myse...

My son washed out the front end of the TTR, now the forks and handlebars are not aligned. The bars are favoring the right side of the bike. Do I need to loosen to the headstem bolt, or do I start with the triple clamps and front axle? I would appreciate your kind assistance with this. Thank you.

Nasty weather here today so decided to spend some workshop time on carbs put back over the years for various reasons.
