OK, so I removed the spark plug completely, on the bike stand I cranked up the peedals and let out the clutch, locks.
I put the plug back in and tried, same thing, locks., I am not getting that "whoomp whoomp" noise anymore either that I got the first time we tried it (had some issues with the chain tensioner when the wheel locked before so I had to fix that first)
Theres no sound at all now just locks up
Hope I didn't break it when we were first trying (the chain jammed at one point)
EDIT: When you say "spin it up a little" do you mean do the clutch in/out process with the spark plug removed, or should it move even without the clutch lever in?
