Test drove the thing , have to edit the videos into one piece ... dont have room to let the thing rev , so i fouled up some plugs
But , with the bigger carburetor ( 27mm venturi vs previous 24mm ) , its set on kill . I havent crossed 40-50 km/h and thats around 10k RPM , maybe even less , and yet it puts me in the seat if i even look at the throttle .
I still havent gone full throttle , need to drive it some amount first for the rotary valve to set in properly , then find a place where i can rev it out to properly tune it .
Currently , per Itsids app , for 10" tyres , 10:88 tooth ratio , and 15k RPM on the engine , speed is 81 km/h . I have a 77 tooth sprocket which i havent tested yet .
