Re: 40cc chainsaw, 65cc-80cc chinese differences?
Yes you are tramp lol...
The problem with the chainsaw is you have to be able to fabricate everything yourself. There is no kit for them.
I run mine as a friction drive and it is too powerful to be a good friction drive for hills. I have yet to get it wot on hills because it skips and goes nuts. On the flat where you could actually wind it out I get chicken.
If you could make your own chain drive it would probably work as well as the china bike. I am just not that talented. Thats as honest an answer as I can give you.
My posts have entertainment value only. A bike ain't yours till it has your blood on it. Then it owns you.
