This is my second build with my new 10G long shaft transfer case and HS 144F-1G 53cc 4-stroke engine.
Customer supplied used 7-speed Genisis 29er.
The cut back case cover shows the larger freewheel bearing in the large pulley to lower pedal drag, which allows for smaller 9T solid sprocket that is adjustable on the shaft.
The bases for the 10G are all a drill to fit the bike.
Once the 2-part 3-point mount base is down and engine bolted on, the carrier bearing plate is attached.
It takes longer to get the engine in, but a pretty simple system to operate and maintain from there.
I like the little extra power a 53cc engine gives over the 49cc.
The NGK 7544 (CR7HIX Iridium) plug, open exhaust, and properly adjusted valves (.04mm intake .06mm exhaust) add more.
Top speed unknown but it rode with the flow in 40mph city traffic with throttle and gears to spare.http://motorbicycling.com//www.pinterest.com/pin/create/extension/
