I now translate the "second car" area with "second car" area, so that my contribution fits in nicely here
.Last weekend I finally had the opportunity to move my "second vehicle".
I remembered the old problem that has already been registered last season and is gradually getting worse.
==References== 5500 rpm the mopped starts to vibrate strongly, so that speeds above 6000 rpm are hardly longer. This is especially noticeable at the handlebar ends, where unfortunately the hands are fastened during the ride.
Very disturbing the whole thing. 1000 km, tending to become stronger.
I don't have an idea where to start looking.
Gradually hardening engine bearings?
"Smuggling" imbalance in a component?
Now due adjustment of the valve play?
It is a GPZ 1100, built in 1996, 39000 km.
The engine is identical to that of the ZZR 1100 except for the cylinder head. ==References== there are typical downtime symptoms with one or the other motorcycle.
Is there anyone who knows?
