Actually I'd take it pretty easy on the trans for your first couple rides and make sure I went back and retightened a handfull of bolts after a few hot/cold cycles of the motor. I hope you found this thread both entertaining and informative. I know I sure had a blast doing it as well as learning a lot. Maybe it will inspire some of you to write a little something about your own project. Now get out there and enjoy your ironhead whether you're going out for a ride...turning some wrenches.....planning some future mods or just daydreaming about past rides!! | Actually I'd take it pretty easy on the trans for your first couple rides and make sure I went back and retightened a handfull of bolts after a few hot/cold cycles of the motor.
