The Turbo TR1 (part 1)

Now I am not the first one to build a Turbocharged TR1 (check out Edgar's Turbo TR1 straight back from the 90ies or his absolutely awesome Topfuel supercharged TR1) and quite honestly it wasn't even remotely in the cards to build a turbo bike, but I am getting a bit ahead of myself.

It all started out with an ad on the German TR1 forum, that said something like: Have flood damaged TR1, needs to be gone. ASAP.

I don't have any pictures of the initial state, but very grim was an understatement. On the other hand it was a low mileage bike that was well maintained, only had two owners and even had some goodies on it like steel-braided brake hose and was a Mk.2 TR1, which meant it already had the bigger oilpump in it and all the innards that weren't suffering from water damage should be in pretty close to perfect nick.

It took me about a month to break the engine loose again, but it turned out, it was only the rings of the front pistons having rusted to the bore. A constant attack with penetrating oil, heat guns, diesel and a socket on a breaker bar finally broke up the little love affair and made it possible to take the engine apart.

One of the very cool features of the TR1 frame is the fact that it is only held on with six bolts, which once removed, mean you can roll away the whole front end with elegant ease...
