The Grubee 50 cc Gen II motor is smoother and revs out more on the top end.
The 66 cc Grubee is torquier and has more bottom end especially with a heavier rider or hills
They are strong motors right out of the box......much faster than a Raw/ PK
i have the 36T installed on a 49CC slant head which has more torque than the standard engine. slightly slower on the take-off than my 66CC but i can cruise at higher speeds with less engine strain. i have the new jet black 66CC slant head on order and will try it out with a 26T sprocket. with this setup up i should be able to cruise close to the 40 MPH barrier.
well i am 130-135 lbs and i am looking to buy a 66cc, how fast do you think i could get going? if you could post a good kit and sprocket combo, it would be very much appreciated, thanks =]
i'll PM you what a cheap high performance setup would be. The 66CC jet black slant head is sold out. mine should arrive next weekend so i'll keep you posted.
