Hey Mike, not sure about lead time. I am looking at early winter before bike goes to shop. So before it does I will remove motor, pull trans gears and drill and tap. Then bring bike and motor to my guy. I read where there are 2 types of plungers, one better than other? Also any input on the proper bolt, washer to plug it till reinstall? I guess I need a premium membership at the least to properly use this site. Thank you, Mike Morra Johnston RI.
