As suggested by brindabella, I have started this thread to show my own choice of "proven/economical/useful workshop consumables". I have started off with my UK thoughts maybe other owners from USA, Australia, etc, can weigh in with their local equivalent brands...... First off, one o...

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?

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...

My fuel tank has rusted through from where the seat has been rubbing on it. Previous owner must have left it bare metal like that for quite a while and there are two holes on the one side. I've attacked it with a wire brush attachment and this is the result: What would you all recommend I do to fix this? I h...

Hello all. Just wondered if anyone had ever had a problem with a slight leak in the carb when standing and not even running. I think (not sure at all) it may be coming from the lid where you access the diaphragm (photo attached). I took the carb off and then tightened everything up. However, still leaki...

Just started a couple days ago, noted that my speed was fluttering by up to 20kph, now, wildly. I even saw it at 170kph today which is obviously impossible. Can some wise head advise, is this likely to be the magnet in process of breaking up or the sensor malfunctioning?

At last a problem with the TTR, near side fork oil seal badly gone, looks a fairly straight forward job, just wondering best place to get the seals and what oil to use. and anything I should be aware of. thanks.

After several years delay (!), I finally completed my sidelined top-end rebuild. All new parts (Wossner piston kit), all machine work sent out to a first-class machinist, 1mm over bore, new valves, cam sprockets, cam chain, etc. Set cam timing meticulously. Before reassembly, I checked the big-e...

Ok. My TTR has developed an annoying habit. It has cut out a dozen times at idle over the past few weeks, so I'm asking for ideas on what might be causing it. Today I took it for a 10-15 minute urban run at 30-40 mph, a 2 mile return trip up a dual carriage way at +60 mph, and finished off with start / stop, 1/4 mil...

After doing the starter clutch & kick starter, I re-fitted the exhaust, as you do. Got the torque wrench onto the exhaust studs and it wouldn't tighten even on about 8 lb.ft. Oh well, **** happens. Any interim repair, other than helicoil? I have a spare head that I will have serviced and fit so I c...

I am now the owner of PO55 OTS; and very happy with this lovely bike - apart from the mystery of the disappearing oil! There is no evidence of oil leaking, it does not smoke but at the end of every ride ( usually about 50 miles of gentle, Cornish lanes) I have to add at least 100ml of oil just to get the level vis...

Hi all, Roberta and I shipped the poor ttr250s back from South America, it really wasn't worth it from a financial perspective but I do like my one!

Greetings, I'm from Sri Lanka where it's rare to find genuine Yamaha parts for the TTR 250. I bought a TTR 250 Raid 06 2 weeks ago, I heard the sprag clutch sound when I was inspecting the bike, however I got a sweet deal for the bike so I had my mind set to fix it once I reach home. Fast forward to today, I remove...
