My b-i-l Keith's exhaust fractured between the header pipe and mount. He managed to repair it using a small length of flexible exhaust pipe with an inner diameter of just over 41mm. This meant he could use a standard TTR graphite exhaust gasket at each end. Ideally he needs smaller clamps. Not sure tha...

Greetings, I have a 2001 US model with the OE yellow spring. The FAQ states: "standard OE yellow springs have a spring rate of 4.9 kgs/mm - allegedly!" . https://www.racetech.com/ProductSearch/12/Yamaha/TTR250/2001

Hi all, as some of you may know I have both a WRR & TTR well I'm thinking of going back to dual sport tyres on the TTR to use on the gravel rds & the twisty black top. Will keep MT21's on the WRR so I don't really need lots of grip in the mud for the TTR. Has anyone tried of know of these tyresMaxxis M6006 12...

The alarm on my TTR drains the battery so I wired in a permanent plug to connect a Ni-Cad jump starter. It never fails to boost the battery enough to get it started even when the battery is below 12v. This morning when I tried to start, the starter button didn't make a sound, no click, nothing. The lights w...

I just bought a new FMF Q4 slip on exhaust, and thought I would remove the header pipe and clean it up while I had the muffler detached. Though the retaining nuts and plate came right off, there doesn't seem to be enough clearance to actually remove the pipe. I can't pull it forward enough to clear the main...

I have checked and re-checked but cannot find a direction arrow on the sidewall of the tyre I am about to fit. Makes me think maybe the D605s are reversible. Anyone know for sure please? Can't find anything on Google It would be nice to get this job done now as the tyre and workshop are warm Brian

Over the years I have come across many wheel rims that have corroded on the inside next to where the tube valve and/or rim lock fits. Water (and maybe even salty water in the winter) gets in and starts the corrosion. The best way to prevent this happening is quite simple. Fit seals to the tube valves and a r...

So my TTR250 20016 blue model confuses me a bit. The only remnant of indicators is the indicator switch on the handlebar. There aren't even any holes or brackets where indicators used to be. Also no trace of a relay on the harness. So I've gone and bought LED indicators as well as the appropriate relay. I...

Just fitting a new set of D&D decals and started with the rear mudguard as it's the easiest to do. I haven't fitted decals for ages and it took a little while to remember the little tricks. Quite pleased with the result. Fork legs next, then side panels and tank.

OK – so this doesn’t feature a TTR tank but the principles will be the same! I went into my workshop one morning and it stank of petrol.

Hi guys, please help, I just can’t seem to get the rubber seal from the generator on the crankcase to seal, it is, as they say”pissing out”. I’ve tried squirting gasket gunk round it, but so far to no avail. All sensible ideas welcome, cheers, Brad

Long time since I've been around here! Back on the TTR and have been noticing some odd gearbox behavior. Specifically, un-cooperative shifting gears when idling at standstill. Doesn't like going from Neutral to 1st or 2nd, or indeed shifting down from any higher gears if I coast to a standstill. Lev...

Hi recently bought my TTR 250. The first ride revealed that the front end seems to ping off most things rather than suspend nicely.

Hi there does anyone have a spare oil pump pin for sale or know the dimensions? I have lost mine during the rebuild process. If you have the dimensions then potentially I may be able to use a hardened needle bearing (cut to size)? Thanks, I'm annoyed I lost mine!
