Thanks for everyones input!
History of the bike is farely unknown. Last owner (around 55 year old man) bought the bike from Germany somewhere in the early 2000’s. He drove it as a daily ride until he put in to barn around 10 years ago. He said that he drove it to the barn. It was a real mess outyside and I predicted it would be the same inside the motor as well.
Well when I bought it last fall, I cleaned the carbs, bought new coils and put new gasoline to get it running. I think it ran with 3 cylinders only. When I dismantled the head, nr. 3 cylinder was ”wet”. I think it didn’t fire...
I looked at the valves and think they haven’t touched pistons. It’s only a trick of light.
This is my first engine overhaul so help is appreciated
If I’d buy a second hand head and for exampple SPS JR3 cams, can I be using valves etc. From my old head given that they are ok?
Thanks for all!
