I just purchased a McKees Bros. Roughrider.I was told there was a 399 Yamaha snowmobile motor in it at one time.I want to replace it with a B.S. or a Techumsa 4 cycle.Am I going to have to buy a special clutch for whichever motor I choose since it will be a four stroke?Will a two stroke clutch work? and lastly it appears that there isnt a transmission in it like the max or the argo transmission.It appears to be two belt pulleys with a main drive belt off the clutch in the middle.Does anyone know what Im looking at with this system and can someone explain how it operates and is it a reliable system?

Chris, We have a Roughrider my boys have been working on for a while. It does drive with the two belts. When you push a handle bar down half way it releases tension on the belt and stops drive to that side ,then push all the way down on the handle bar and the disc brake locks that side for a sharper turn. It doesn't have a reverse gear. One nice thing about the Roughrider is that most of the parts are not specially made and can be bought at a bearing supply store.

Thanks for the reply,I appreciate it.
Im kind of lost with this thing.The body is really nice,has no motor.I was just confused when I looked at the drive train.As a matter of fact I cant even see a disc brake mounted anywhere in the tub.everything else seems to be there though.What kind of motor do you have in yours?And would there be anyway you could send me a few pics so I can look at yours and compare what I have to yours?
