Years ago when I last went riding I used to fill up my backpack with all types of useless crap that was heavy and probably only usefull on everyone elses bikes. What basic tools and spares specifically suited to a TTR should I carry as a minimum? Generally we wouldn't venture anymore than about 100km...

So, I'm looking for more power! I have a '94 raid. I am hoping to add electric grips and an electric vest. Grips run at about 60 watts. That's almost half of what the stator produces. Are there any aftermarket stators for the bike? Am I looking at a rebuild?

Hi All, I went to start my bike the other day and it would not start. It wasn't sparking.....arghhhhhhh So I'm not experienced with diagnosing electrics but I think I've followed all the testing in the TTR250L service manual, at least I have tried to.

Hi all, I was out a couple of weekends ago on the TTR for the Borders Rally - first rally and a fantastic weekend... until the bike lost all drive!

Hi all,I have a problem with the charging system on my newly acquired TTR250 1995.Symptoms are battery drain of 0.2V/hour, so it’s flat the next day. Also no charging when I rev the bike quite high(I don’t have an inductive tachometer) – the voltage across the battery stays at its initial charge of ap...

I was wondering if anyone could recommend a torque wrench for the bike? I've got some vouchers for Amazon and will only be able to get a cheapish one. I think I'll need a 3/8" drive with about 5-25Nm torque or so. Can anyone recommend a good brand? It would come in handy for the car too. Thanks, Dave....

PO55 in pieces again - I do not love this bike - and just to make my life more interesting, one of the exhaust manifold nuts sheared off when I was removing the exhaust pipe. Any advice as to how to remove the stud - I have tried loads of WD40 and heating with the blow torch, but it still wont budge.
