Hi BS,
I am just back from about 3600 km holiday touring with the TR1 around Scotland and the engine still turns quiet round and round and round......
There are no suspicious particles on the magnetic oil screw so I believe that this conversion works.
My intention was not to save money but to have a controlled non-located bearing on crankshaft main bearing. As you can see on my former pictures there was a lot of rust on the old crank journal because of its minor bearing play. Now the inner race of the roller bearing is fixed with loctite.
First I thought that the 90.000 km plus were the reason for wear, but then I could see the same signs of wear on the XVS1100 crank with only 12000 km......
The roller-bearing is also not cheap, something about 75 EUR.
The other ball-bearing on the opposite side has a close fit, was still fine and is in use now on the XVS crank.
Groetjes
