[chewtoy83]

I have a older 6 wheerler with foward and rev tranny double chain I was looking at a 700cc motor out of a seld I have a 16hp in it now

Argo's dont really work well with sled motors in them, noisy,stinky,too hard to turn at low RPM, throw an 18hp B&S V-Twin Vanguard in it you will love it will be like a whole new Argo to you, However anything is better than the 16hp Tejuncksy you have in there now

a 700cc 2 stroke will be way too much!stay with the four stroke and live with low top end speed!from what ive read here a 440cc kohler 2 stroke(mid70s) will do 45 mph.i know of someone that put a 640cc rotax in place of the440.it was INSANE!he wound up destroying the machine!
