I mentioned in another post that I was in the process of resurrecting a blue TTR after some years of storage. I am almost at the point of starting it but on refitting the starter noticed some marks in the larger of the two gears that sit under the round cover. 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...

Is this likely to be the rectifier unit and, if so, where and how much for a new one?

TTRfan · TTRfan

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...

What is the highest you have seen on a straight engine? I bumped into a fellow TTR rider at the weekend and he had 40k on his one. Although he told me it had 4 owners so someone may have done some engine work in it I guess...

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. Having rebuilt the bike to a 350 and using a air fuel ratio gauge I'm trying to ensure it's running nice however I'm having a bit o...

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. I have done some reading on the forum and understand that it could be a cracked generator cover case caused by the sprang clutch making a clack noise on shutdown and sending a sho...

Hi, does anybody know where I can get the just the pet**** filters from? They‘ve all but disintegrated on my new project. They’re not listed as being able to purchase separately - I‘m going to install an in-line filter in the fuel pipe but as I’ve got the fuel tap off to clean the tank out thought I may as we...

Hi Team, I am not new to this forum, I had posted a while back that my rear shock keeps leaking after repairing it. Lasts a few weeks after I install a new seal head bought from Totally TTR.

Hi All I have an oil seal that is leaking oil out and I have tracked it down to the Push Lever assembly seal. Does any one have a step by set instruction or video on this .

Hi my 250 Ttr250 is fitted with the raid headlight. cant see a front sidelight, or a fitment for one, does it need one for a mot ? . rear works fine but baffling me why the front end don’t have one. cheers.

Hi folks, Last MOT I got a verbal advisory to sort out the rear brake pedal as it wiggles on the shaft on the frame. I get the feeling the pedal should be held in place by a circlip or similar. Unfortunately on my bike one of the previous owners has welded a washer on to the shaft to keep the pedal in place. Befo...

Have just done a complete rebuild on my old 1996 TTR250....long overdue. She has fired up fine, except for an odd oil leak coming out of the clutch push lever seal.
