hi people my mates got a fantic k-roo 1993 212cc,we have just rebuilt the engine today.started it up and it sounded like the points needed a little adjustment so we go the flywheel pully on it and removed it no problem,done the adjustement to the pointsand put the flywheel back on but i noticed he started the bike up without tightning the flywheel nut up,the points were still not right so we put the pully back on and now it wont budge and its bent the pully,any ideas to whats happened?thanks james
