Hi!
I´m the proud owner of a Tr1 for 20 years now. She´s been standing in the garage for the last six years, due to a problem which I haven´t been able to solve up to now. Recently I stumbled across this fantastic site and I hope that someone can help me. My motor runs rough!!! I´ve tried everything I can think of to solve the problem, without sucess. I changed the crankshaft of the rear cylinder because I thought the "hammering" came from there, but "no success". I replaced valves were I thought it was necessary, but "no success". All valves have been adjusted according to the manual. The same applies to the motor. I´m puzzled! Realy, I don´t know what else I can do to solve the problem. Maybe one of you can help me.
Here a brief description of the problem. The motor isn´t running as smooth as it used to years ago. At the moment it sounds as if a piston is hammering against a valve or something else, but it´s not, I,ve already tested this posibility. Just imaginge it as if you hear a running motor and there is a little "Gremmilin" inside the motor with a very big hammer knocking against some part of the motor. The higher the rev´s, the faster the knocking. It realy sounds horrible. By the way, top speed is about 150 km/h. (HP has not been reduced!)
I hope that someone can help me. I would so much like to see you at the next "TR1 Treffen" and shout you a beer or two.
See you around,
Randy Andy

Hi Lutze,
danke für den Tip. Ich werde die Ölversorgung gleich mal checken und berichten ob mit Erfolg. Übrigens, in meinem Text habe ich einen Fehler gemacht (erst nach dem Senden gemerk). Nicht die Kurbelwelle des hinteren Zylinders habe ich gewechselt, sondern die Nockenwelle. An der Kurbelwelle wurden beide Lager ausgetauscht.
Bis dann also
Andreas
