First, some proof that we have some knowledge of - and support for - the TR1. Click on any picture for a larger image.
NOTE: I need measuremnts for the depression around the bore. I plan on mfg a copper gasket that will squeeze into place. If your motor is apart, please send me these measurements; especially height. It will be slightly larger then a stock head gasket. THe TR1 was not sold stateside, so I need this so you'll get as good a seal as we do here. Whoever contacts me with this info first will get a free pair with any purchase.
Note that those shots with the tooltips "Norway" have the bad barrels detailed on the following page. Those denoted "Finland" are the good style.
Now that you have wet your beak, read up on what we can get for your bike: Pistons
