The drive wheel is a 10 inch tire with billet alu wheel 76 tooth rear sprocket size #25 chain 10 tooth front sprocket (the road gear since im in kansas) i have gotten it to 42mph on a long flat stretch the 6 tooth gear i have tops out around 25-30 but is much better on hills of course.
one of the advantages to this engine is on the flywheel it has the the cooling fans like a lawnmower to keep the engine cooler than just wind alone.
but its only rated at 2.5 horse mines probably around 2.7 with my slightly opened up exhaust. since this is a goped engine i can get loads of aftermarket parts for it as well tuned pipes all that jazz but 160 for a pipe seems harsh im more of a fabricator so one of these days
i do however have a new project in the making im going to take one of these china motor kits (or maybe a small 4 stroke) and put it in a streched frame bananna seat bike from the 70's
i found the bike next to a creek (on my parents land) lonnnnnggg ago and went back to where it was and it was still there it has some rust but nothing too bad and no the frame isnt streched already thats what i have to do
it may be a long project this bike has the triple tubes on top for the frame one large tube where it should be across the top ,,,,,and 1 much smaller tube on each side of the frame about an inch away from it .
this is one of those ones that had dirtbike number plackards on them with the cool bent out forks and mega far back bananna seat but the frame is very short length i will need to stretch it at least a foot for me to ride comfortably :???:
