difference between Grubee Starfire and Grubee Skyhawk ???

Starfire motors come from the Nantong Jiali factory (NTJL), the Skyhawk motors are made by the Yuang Dong factory. (YD)

I am unaware that there is a Gen II made by YD with the Skyhawk name. Do you have a product link?

(FWIW, the NTJL engines are the best IMO)
 
Arceeguy I have the Starfire motor kit on my bike from Kingsmotoredbikes..running good 400miles ..have upgrades and was thinking of getting a spare motor......Have MM sprocket and adapter installed..well Kings is having sale for one more week..I can get a Skyhawk complete kit for less than buying another Staffire (motor only) ....Was wondering if the Skyhawk and the Starfire had the same case length and mounting hole dimensions
 
:D Well, I have the Skyhawk Slant 48 g2......Same miles at this point 389. Does great at 32:1,NGK,Wire,SBP expansion, port matched. I'm 6' 6", 255, and does very well considering. I go easy on it, but on flat once ran 34+ on 26" MTB.:cool:
