hi everyone, i have a 01 raptor 660 that i was replacing the gaskets and piston rings on. I went to bolt the cylander on the crankcase and it was not threading in and kept spinning. Pulled the bolt out and the thread came with it. So what would my options be to repair it since the thread came out with it? i thought of using a time-sert but then realized its the one bolt that dowell or spacer on the bottom of cylander. if you would be sitting on the raptor it would be the left rear bolt. Would a helicoil work? thanks in advance
