Dying when a crappy china gal motor craps out on you in the air is just plain stupid.
Crapping out on the road is usually not a life ending moment, you just pedal home.
But you were never going to do this anyway so no big deal.
if i ever do , do it, i will make sure it ain't no kit bought motors. i've had motors go boom in the first mile and others last thousands. i am crazy enough to do it. just need the free funds, and right now my funds are tied up in more important ventures. i would be building the engines myself, only way i would trust them to push me through the sky. just today i pushed a 66cc up to 42.9mph( on a flat road) on a 24" bike with a 32th sprocket. i was flying and pushing tht motor way harder then she ever wanted to go. stock she was a 30-32mph an a bit faster down hill, i chewed up her ports and etc etc and she still wouldn't go past 37 till i decided to play with the magneto. needless to say, she died with a horrible scream and a boom( literally sounded like a bomb went off between my legs). needle bearing decided it was breaking up with the piston and the gudgeon pin. idk my rpms, my tach stops at 9999, an im to lazy to do the math. my back wheel locked for just a split second (i knew it was coming when i heard the piston slapping so i held my hand on the clutch), which lunged me up on the seat and i snapped the clutch in. a guy down the street that i compete with to make the fastest bikes, seen me pedaling my bike up a hill and laughed. well until i told him i'm now in the lead again by just over 3 mph. so now we have a drag race set up for when i rebuild this one. probably gonna switch to a bushing con rod on this re build. when it blew, it took a chunk of the transfer wall off and cracked the jug. will make a fine paper weight now.
edit: and if you are wondering, i am 170lbs and my bike is another 80lbs ( welded it up myself from scrap bikes and scrap metal i had lying around) and yes i was tucked as tight as i could with little to no wind.
