Good day to highly reputable forum people!
I have a running project K75 RT and I just took it to first longer drive after I bought it. The bike had motor swap 10 years ago and was left to sit for 10 years. Motor was changed because the clutch was literally ripping itself apart every 20 to 200km. Best guess being there was something off in engine-clutch-gearbox alignment. The engine that was swapped out has one of the engine's aluminum mount rebuilt. Also fairings have seen some fixing on the other side. So it has been crashed at some point.
I suspect that I might have slightly damaged frame geometry. I took one of the front engine mounts loose and it was 2 to 3 cm of the line. When I put it back I had to bend the front mounting bar to get it on spot. Should the engine mounts be perfectly lined by standard? Also on my resent ride I noticed that the bike is slightly pulling to the right. On straight and even highway I had to keep light counter steering pressure to the left. If I took my hands of the bar the bike started to tilt right.

So my question would be that are such imperfections normal on any standard? It is 3 decades old bike but should bee of decent building quality.
