1300 miles on my 66cc Bikeberry until it died. RIP
280 miles on my 66cc BGF until it died. Good riddance!
500 miles on my 66cc Grubee Skyhawk GT5 and still not a problem.
800 miles on my Mitsubishi TLE43 and still going strong.
In 2 months, I've put 658 miles on my skyhawk 66cc. I'm about 210 lbs, and I have panniers and a rack trunk on it. I run it rich and cruise at 18.5-19.5 mph (law here is 20 mph). Still runs like the day I bought it.
Around 900 miles on my 2009 48cc Starfire gt2 grubee dualstart dualclutch engine from gasbike and runs better than new. Its mounted on a 2009 scwhinn delmar cruiser.
I have 2 plastic bins on the sides of my rear rack for grocerys.
I have no aircleaner(just a screen) on my intake pipe and stock black cat muffler. I run wot around 30mph 1 mile to the store and 1 mile back home every few days.
2500 miles on my ht, new top end rebuild at 2200 miles as i was upgrading the top end bearing and shimming. Chrome was starting to wear off so i put in new piston and rings. I am running 160 lbs compression now so well see how long this top end lasts.
