Good job, man. Thanks for posting.
I have a cheap freewheel on my chainring sprocket. It wobbles so much that you can measure the runout with a ruler, lol. They're cheap, they wobble, but mine hasn't broken yet.
Aint shift kits the greatest? What's your gear ratio?
My friend used Staton's new lube on his twin-engined gearbox. Since there's no gasket or silicone seal between the gearbox halves, all the lube leaked out. He eventually blew the gearbox. It's back at Staton's awaiting a complete overhaul. This time, I'll be using old fashioned grease. That's what Staton used for years on his gearboxes.
I'll be running twin GP 460 engines, but that's another story, lol.
