ive ridden my skyhawk 66/80cc engine on my beach cruiser nearly daily since middle august. i estimate ive put nearly 1,500 miles on it riding in-town, stop and go while usually achieving prolonged speeds of near 30mph when she'll do it. i was just wondering what average lifespan (mileage wise) is. id heard that grubee was an off-brand Honda, but not expecting the same kinda lifespan my 93 Accord produced. any insight into this? im starting to have little ticky tacky problems and wonder is this the end of the line coming up?
