Figure about 28MPH direct drive for the less speedy family members, and make a couple of jackshafted 3-speed shifters for those that need more versatility (climb hills, haul ass, or tow another bike).
That's what I would so if was a worrier like you ;-}
I agree KC,
If he has the funds to invest the most reliable option is gonna be the 4 Stroke set up.
I don't use them so it never even crossed my mind, I always have the 2 smokers on my mind.
another advantage like you mentioned KC is the part of being able to run straight gasoline and not needing to worry about 2 cycle oil, in a survival type situation that could be a deal breaker if you could find any oil.
If at least regular motor oil could be found you could premix with it and get by, but the enemy would see and smell you coming from a long way off...LOL...!!! Sorry DirtyNails I couldn't help putting this in here..
