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...

Ive looked through some of the older threads and I cant seem to find anything on replacing the front wheel bearings. Does anyone have a guide for that project? Also the torque specs for the axle nut and pinch bolts. Any help would be greatly appreciated. Thank y'all in advanced as always.

Fast forward to today, I remove...
