TDR 250 rebuild thread
-
Barrels and ylinder head dropped off for vapour blasting, pistons and powervalves cleaned. Historic damage to slave powervalve visible, looks like rings have contacted edge of powervalve sometime. Checked prior to strip down and not visible in dirty photos. Best guess is powervalve linkage from driven powervalve to slave failed at some point allowing it to rotate at will. Existing linkage fell apart when I removed heads (have received new one for rebuild)
Did buy a new tool a few weeks ago that deserves a mention, 18v Dewalt impact wrench, should have bought one years ago!

When I bought the TDR it had the popular "upgrade" of TZR wheels, I picked up some refinished original wheels at the same time I bought the bike and stuck them in the loft. One of the reasons for the TZR wheels is the far better choice of tyres, the standard ones are 18" and 17", leaving a realistic choice of 2 brands, Bridgestone BT45 or Avon Roadriders, checked the reviews for both and Bridgestone the obvious choice .
Have ordered the spindles and spacers to suit so all ready when needed.

Collected my frame, barrels and cylinder head today, very happy with how well its come out. Still waiting for some parts from Fowlers for bottom end of engine on back order, did receive suitable wheel spindles from Greece with correct spacers for original wheels though. Want to get decent shock or new one in the next couple of weeks though, can lock myself in garage over the Christmas period then. Do intend on a Christmas day ride on something though, always used to do it years ago but lost the habit in recent times.

@calum It's a standard powder coat colour, graphite. A shade darker but a very close match on the finish. The best recoat of a frame so far, but I did explain I wanted a premium job doing and paid a bit more to achieve what I wanted. Will be taking other parts needing refinishing soon.

@calum It has got a subdued metallic finish, much like the original . In the flesh it looks impressive, factory fresh. As with all powder coating the vin on frame is somewhat diminished but the TDR has a data plate that rivets to side frame tube so no moans from the mot tester hopefully
