I'm in the process of replacing my first top end. I have a few questions if anyone can help me out.
1. I'm going to wash the cylinder in soapy water with a scotch brite. When I do this do I have to remove the powervalve parts? Will the water get caught up somewhere if I leave the powervalve parts in place?
2. I'm going to spray oven cleaner on the powervalve parts and exhaust valve to get what gunk I can see. The powervalve doesn't seem to be sticking and I really don't want to take it apart. Can I get away with cleaning the powervalve while it's still assembled in the cylinder?
3. The powervalve seems to have a bearing that's exposed when the powervalve cover is removed. After cleaning, do I need to regrease this bearing or just coat the entire powervalve assembly in 2 stroke oil?
4. When I put the rings on the piston, what's the orientation of each ring gap? If the intake was 12 o'clock where would the top gap be and where would the bottom gap be?
Thanks for any help,
Mike
