This little tank arrived from India (via eBay) this morning. I am going to use it to test carb float levels and for leaks BEFORE putting the carb on the bike and save myself possible hassle I am also hoping that it'll save the inevitable spillages that occur whenever I try to do anything involving petr...

Or, to ask the question in a different way, does the bolt go in from the RHS (exhaust) of the bike or LHS (chain/sprocket side)? The manual shows it both ways

Hi all. I now own a 1996 ttr250 and I really like it. I do have an issue with it tho. There is a black plastic sleeve that connects the carb to the head. I've noticed that it looks perished and bits falling off it. (On the head side) the engine ticks over okay but eventually it will make a big POP then cut out. I'...

as my bike is fairly new to me the previous owner cobbled up a rubber flap type thingy bob to protect the rear shock which worked fine until the fitting of a new ac10 tyre which after a ride in the peak district is now destroyed, my question is can you get a replacement or is it a Yamaha part only ? Ive tried pol...

The fork legs have been totally dis-assembled and the lower fork legs resprayed in hard wearing "wheel silver" All the parts have been thoroughly cleaned and are ready for re-assembly using a fork and dust seal kit I picked up from Totally TTR Towers yesterday - see here - the kits will soon be back in s...

Hi, I am trying to put the settings back to the standard setting, and the rebound adjuster says it should be "9 Clicks out". I have got myself confused and now wonder which direction "out" means. Is it out away from the spring, or out away from the lower mounting? Sorry if this is yet another daft quest...

Hi, The TTR was never a bike made in large numbers, therefore the availability of parts is not great. Over the last years i have been always looking for some other yamaha machine that could share the same engine, and therefore possibly extend the sources for parts. It seems like i found it! Found a yamah...

Hi and a happy new year to you all, Can anyone tell me what stops the kick start lever at the end of its travel when you kick down on it? On a friends blue tank model TTR250 the lever stops just before reaching the riders foot peg holder. I have the same model but my lever slams into the foot peg holder, and wh...

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...

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. The original owner had put new seals on and replaced the oil for 7.5wt. I was wondering if anyone uses lighter wt oil such as 5wt to soften the forks? the tyre i noticed are in...
