I know most of you folks are mad scientists of the highest order but I have to ask again, Why? We've got single cylinder 2-cycle engines here most of which are made with questionable QA standards. For what you spend modifying these engines so you can blow them up you could buy a motorcycle with more power than you'll ever get out of these things. Yeah I know I'm being a wet blanket but I just don't see the point. I'm all for accessories that make them safer or easier to mount and use but going for excessive power seems kind of pointless to me.
If it can't be broken I'll find a way!
I'm not lost, I'm exploring!
