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

So, I'm looking for more power! I have a '94 raid. I am hoping to add electric grips and an electric vest. Grips run at about 60 watts. That's almost half of what the stator produces. Are there any aftermarket stators for the bike? Am I looking at a rebuild?

Years ago when I last went riding I used to fill up my backpack with all types of useless crap that was heavy and probably only usefull on everyone elses bikes. What basic tools and spares specifically suited to a TTR should I carry as a minimum? Generally we wouldn't venture anymore than about 100km...

Hi Team, My Carb has been leaking fuel and just got worse. Droplets of fuel trickle from below, even when the bike is not in motion.Now I am forced to close the tap everytime I stop to minimize the leakage. I have tried to clean and remove any kind of blockage but it still leaks.Help Kind Regards Vincent

G'day all. I was wondering if anyone has tried the Webcam camshafts on their TTR. I have just completed a 325cc build and was wondering if the cams would make any difference

Confused is not the word😂😂😂 Having spent the last 21 years riding the same road bike and therefore the same tyre sizes, looking for tyres for my Raid is a confusing place to be The recommended sizes are: f 3.00 - 21 51p r 4.60 - 18 Fitted tyres are: f 90/90 - 21 63p r 110/...

Hi team, What would cause the clutch unit to look like it was burning up? See attached photos, I had opened it up few months ago to add a new set of clutch plates then after a while that is the look I get on the clutch plates. Please advise. Kind Regards

Hi fellas. My Raid's rear shock is a bit weepy, will need replacing at some point. I looked around, seem to be that Raid shocks are different from Open enduro? Please correct me if I'm wrong. If they're different, how do I find the right size for Raid? When I search online, it does not come up as a separa...

Hi As above, if I set the clock and reset the trips, after the ignition is switched off and on again the clocks reading 1-00 & the trip shows 51 A&B . Is there a backup battery in the unit somewhere that holds the info or do I need a new unit.

I mentioned in another post that I was in the process of resurrecting a blue TTR after some years of storage.

I have attached a picture of the indentations in...

Hi All, It has been a while since I last posted but I thought I would get back on the 'horse' - power that is. I have recently had to spend a lot of time getting my old TTR running again because of old fuel and a battery that is also getting old. Normally when I know it is going to be a while before I can get back o...

Hello to you all, After a delay of some 5 years or so i have started to complete the rebuild of my blue TTR. Rolling chassis with new powder coating is all complete. I was in the process of replacing the cylinder head when I realised I'd put the cam chain blade in upside down. Off came the head but it took the...

When I look where the bearings will fit, there is a lip perhaps an inch in where the bore size is smaller Should the bearing be pushed in until it stops against the lip This will leave the bearing about 15mm in from the outside edge of the swingarm No pictures as I've already pushed them in so that they are f...

Hi all. Hope you're having a good day. I'm hunting for a ttr, found one in Cornwall, the Open Enduro, but it's problematic. Talked to the guy on the phone, sounded reasonable and no bull****, he said it's hard to downshift. Shifts up well. He thought it's a clutch, replaced, but problem persists. I'...

Well as I have posted on a previous topic I was going to fit dual sport / adventure tyres on the TTR, will keep MT21's on the WRR for the rough tracks, going to keep the TTR for dirt /gravel roads. Had a delivery from postman Pat today, so on a 39-40c day I changed both tyres, not sure about the front but I guess...

My rebuilds often advance at a snail's pace so that much of the oil I use on assembly has probably long gone by the time I get to run the engine. I belong to a few classic bike FB groups and there were a lot of experienced guys recommending Graphogen. Not cheap at £27 but its a big tube - 125g - and will probably...

Hi all, My bike starts okay however my cams are both slightly off level when tdc (single mark). I have recently replaced the cam chain (2000 miles Max) so wasn't too worried.

I've been having some trouble with my bike bogging down and cutting out when I apply the throttle. After a few chats and looking around I decided that it would be best to clean the carb. There was some build up and so I cleaned it no bother and put it all back together and slapped it on the big. When we went...

Hi, my Australian 2006 ttr250 has recently developed an oil leak which seems to be coming from underneath the starter motor.

Hello All! I have the rear shock out of my bike for a new upper bearing, and decided this would be a good time to check to make sure the strut is still in good working order.
