I want to build a 4x4 cross cart with IRS I was looking at potentially getting a sportsman 850 transmission and hooking a 100hp vtwin to it but this is a option now too hmm
What annoys me is the gearbox is rated for 20 or so horsepower yet you have to run a 530 chain and you run an oddball sprocket so you can't find one that will fit to run a normal 420 size chain.
Yeah, I'm sure somebody will make a 420 sprocket as this gearbox gains popularity. Until then, we stuck with the 530. Lots of motorcycle sprocket options. Some sprint cars using with the 5.25 split bolt pattern/ 530 combo..
Thanks so much. I didn't know much about gearboxs till I watched this. Getting ready to do an electric to gas swap on a golf cart.
Good Luck with your project! Let me know if I can help.

Does either of them use a chain inside like the old Foote transmissions. Or are they all gears?
Good question. Not familiar with those.
How much speed is lost using this?
Hard to say, but you will go way faster in reverse!
When going forwards, basically none. They have 1:1.3 ratio forwards and 1:2.6 in reverse.
