Hello from Adelaide, South Australia
Been around motor bicycling for a while now.
My main project at the moment is converting my 2 banga to a 4 banga.
Mounted a Honda GXH50 with a Grubee box.
I have had a trial run with the 4 stroke and I am impressed on how smooth it is.
It is quite a different ride experience.
Not sure how the top end will be and from what I have read it will be ok but I haven't run it too hard as it will be run in for a while first (a little while anyway!).
I'll stop now as I don't want to get off topic!
