So I put together my kit over a month ago, and have had a lot of ride time on it already. As far as i and a friend know, everything has been put together right, with all the stock parts (it's a Grubee Skyhawk 2-stroke 66cc). It's on a basic Schwinn cruiser bike, I put a real strong wider wheel on the back and a thinner wheel on the front. Last night, i had a friend drive his car right beside me on a few long straight-away roads at my bike's full throttle, but according to his speedometer, i was maxing out at around 32mph...... This was kinda disappointing, i thought i've been somewhere 40 and 45mph.. Since the start, i've removed all the fenders and replaced a bunch of minor parts on the bike, so it's already pretty lightweight. What improvements can I make to get more power/speed? Are there any better parts online i can replace the stock parts with that would improve performance? Any homemade ideas that anyone has? Thanks!!
