Hi,
Pretty much any kit would cope with that - the only issues are reliablity, longevity and what look & system you prefer...
We can do... and have:-
Chain drive single ratio
Chain drive geared
Belt drive
2 stroke rack mount
4 stroke rack mount
2/4 stroke frame mount
25cc - 100cc+ displacements
pedal/clutch start - recoil start - even electric start if you are lazy lol
Its probably cheaper and more effective in the long run to invest in one of the better kits - it may also be safer as the problems with these are already ironed out and people know what to look for and how to troubleshoot them...
good luck in your search..
