40 mph IS a lot of air.
I took mine all apart yesterday to put a shaft from this production lot on. And finally did the clutch cover reverse bolt option. My homemade grease held up well!!
No unusual wear was noted on the shaft, gears, chains or bearings.
1) TAKE THE TIME TO FILE AND SAND THE KEYWAYS AND KEYS. MAKES THE FIT AND ASSEMBLY REALLY EASY IF ALL SLIDE FREELY. TAKING YOUR TIME LIKE A FINE MODEL OR CRAFT, REALLY PAYS OFF.
2) ABSOLUTE FARTLUTELY USE LOCKTITE ON THE SET SCREWS ON THE SMALL GEAR. I THINK I LOST ABOUT 3 OR 4 SETS NOW. WITH LOCTITE, NOT ONE.
3) MAKE SURE SMALL GEAR IS WELL LINED UP WITH OUTER CHAIN RING.
4) GLAD TO KNOW YOU GUYS WILL PAINT YOUR BRACKETS!
