Hey everyone I was just wondering if someone would be kind enough to explain how the jetting works, and how to rejet. I have a blue 2000 ttr with what I asume to be stock jets. I have installed an aftermarket exhaust and I think it's running a bit rich. How ever I have no clue about jetting. Thanks Aidan

Hi all, had my first big blast on new bike, and just wondering how my old raid compares to other TTR's out there, now I took it over Exmoor and up Porlock Hill (steep and a little cheeky if your not familiar with it) and made it up and down without issue. I have to work the box a lot more than any other bike I've h...

I am asking onn behalf of a good friend, who also has a TTR 250. He can't get the starter to turn over, even though the the battery is charged. This problem just seemed to happen without warning. Any ideas as to what he might do to solve this problem?

In an effort to quiet down my after-market exhaust system, I have inserted a copper grill scrubber into the end of the muffler. I was also hoping to reduce the flow and help the bike run a little smoother. (She seems to prefer to run with the choke on a bit.) If the bike is not running poorly with this add...

My side stand can be a real pain to kick down/up again. I've dismantled the linkage, greased it and nipped it back up. It continues to misbehave! Seems it needs a bearing or something for it to work properly, don't have this problem on my DRZ or CBR600, or any other bike I've owned. Ideas please?

First of all, I really like my new (to me) 2000 TTR-250. But, is there a modern, small bike on which this is a more difficult task to do well? First of all, little bay in which the plug is placed is a terrific place to collect dirt leaves, small rocks, sand, etc. Second, you can't see what is there to make su...

Is the polisport item a viable UPgrade or is it the SAMEgrade. I mean is it much brighter?? My friends have polisport lights on KTMs but there 100w, I noticed the polisport item is the same wattage as standard. Any other suggestions?? I have an Open Enduro BTW.

My rear gear lever appears to have developed a reasonable amount of play on it, side to side and now rests nearer to the engine than I would like for my foot to "find" the lever I've just had it apart and it seems loose in the mounting hole - any ideas on how to sort this/what bits I need to replace...

I recently bought a TTR that had starter gear problems and was kickstart only. It was only used off road so had no need for lights etc. The previous owner must have been quite knowledgeable about bike electrics because he managed to get a working TTR using only a very small part of the original loom as in t...

Hi all, basic questions time. I haven't got any rim locks, but guess they would be a good idea, I have a couple of rubber bungs- so: Do I just buy some locks and they are really straight forward to attach? Do I need a certain size (s) Can I really muff it up as I'm not sure really what I'm doing. Thanks as ever
