Hi chaps, Is anyone familiar with brazing fuel tanks? I'm going to attempt this on my OE tank, as I wanted something a little more permanent than an adhesive filler. Apart from the obvious 'make sure there is no explosive residue' are there any important steps to follow? I didn't want to weld the tank at...

I have a 1993 TTR250 OE, has all the normal things done but i would like a bit more noise as i ride mainly in traffic at the moment. Is there any information on baffle modification in the standard muffler, to get a bit more thump out of the old beast.

Pretty much all of the powder coat has chipped off my outer engine casings, and was wondering if this could be a symptom of something more serious, like overheating or fatigue? If I cleaned and polished up the alloy would it be durable enough for the vigors of offroading, or am I going to need to paint/po...

Hi all I have a blue 02. It won't start on the kick starter. It will return when I kick it & I can hear whirling inside but there is no great resistance when I kick. Is it engaging? Is it slipping?

Last time I was out of my TTr (last year I am afraid to admit) I was being followed by a guy who used to work for Geraint Jones and at the UK Yamaha Off Road School. He observed that that my control would improve with a firmer front end. He said that at the Yam School they had some discs of 10mm thickness machi...

I bought this TTR from a mate, for £450, and since getting it home I have found a few faults and noticed missing parts. (Didn't stop me from taking it out and getting it dirty though) It's pretty hard to start due to the long throw of the kickstart lever, or possibly even low compression. It needs to be jus...

There have been a number of on-forum and offline queries about smoking engines in the last few days so I thought it might be worth putting my thoughts down here for you guys either to shoot down in flames or improve upon If the smoke is the only symptom and the engine isn’t rattling then there is a very goo...
