Following prompting from Brian, I shall now attempt to give some help regarding changing the lock barrel on an OE fuel cap: 1: Give the whole cap a good soaking in penetrating oil to loosen up any dirt and rust 2: Undo the 2 screws that hold the locking mechanism in place, taking care to hold pressure on it...

There has been a number of questions about changing the TTR's oil and filter so I took some pics of the oil change I have just done. I will explain how I do it but you may well decide to do things your own way. Warm the engine first as the warm circulated oil will drain more easily and carry any debris with it. R...

This guide shows how to replacing the steering head bearings with new using an AllBalls kit Firstly remove the old outer bearing races. I used a special tool made for the job.

Decided to go with powder coating the shock but it looks like the spring will only come of from the bottom. Therefore I need to disconeect the oil chamber. Does this need to be filled/pressurised to go back on or can I just disconnect, take off the spring and put it all back together again? I can't find any...

If your original unit is damaged or missing and you are fitting an after-market switch you may need some additional parts. When I was building my project bike, these are the additional parts I needed to properly fit the switch. It is more than likely that you will already have these on your TTR. Firs...

In need of some help. My 2001 ttr 250 has been working great up to this point. Now it won't start. Push the magic button and nothing. The headlight still shines bright but no start. It happened all of a sudden. I went to start in one morning and nothing. I have tried charging the battery but still no power. I...

I have just started to strip the engine for my next project. When I bought the TTR a couple of years ago, I couldn't start it and suspected low compression so it needs investigating. There is already a "show and tell" for removing the cylinder head here so I am trying to think of any hints or ti...

The question has often been asked if OE and Raid seats and tanks were swappable. Well, I had one of each models side by side in the garage today so thought I would try out a swap. This is an Open Enduro with a Raid tank and seat. You can see that it is quite a good fit despite the extra width of the Raid seat at the...

This is an extract from my project bike thread so it may read a little odd in places. I thought it might be useful to start a new thread for this job as the original post will get lost in time.
