I just installed a 66cc "PK80" by runwell from BMW and there is something wrong with the clutch.
I started it 3 days ago, rode to the end of the block and back kept it running to adjust the idle (had to turn the idle screw all the way in) I shut it off.
Anyway I went to start it 5 min. later (for a store run) and the clutch would not grab enough to turn the engine over. So I replaced the pads. I adjusted the clutch the proper way and made it to the store.
. When I left the store I had one more stop to make (Walmart) I barely made it the 2 mile trip because the clutch was slipping.
I rode slow because I'm in the brake in period and to minimize clutch slippage. When I went to leave Walmart same problem, not enough clutch grip to start.
I adjusted the clutch in the parking lot (I always carry a tool kit with everything I need for these engines).
I have had to readjust the clutch 5 or 6 times in 3 days.
The clutch pads that came on this engine were so tight in the cage I broke 5 out of 15 but damaged the other 10. I replaced the pads with a set I had (red) on day 2.
Had to trim 13 of the 15 so they would fit the cage. I haven't found pads yet that fit properly. I'm thinking the spring preload is incorrect on the clutch shaft.
Anyone have any thoughts? And is there anyway to adjust the preload with out removing the shaft?
