Hi, it's a right hand thread, turn to the left to loosen.
Yes, you normally need the puller.
I think you are in Long Beach?
I sell the puller, bevel gear, keys along with all the parts for these motors
not far from you in Anaheim.
Whatever you decide do Not buy that over priced shoddy Chinese knock off
of Sick Bike Parts USA designed kit.
Get it from originators for less with more included and quality parts. www.SickBikeParts.com
Thanks for the report seeing that I don't watch TV.
CA mb law now allows 4 HP motors.
The next Socal Motor Bicycle Racing event is next month on
Sat March 28th at our favorite track Grange Motor Circuit.
Hope to see you there.
