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. 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 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.
