Hi everyone i just wanted to know if i was going to 70cc my 1999 Yamaha Neos chould i still run it with the standard crank or would it be better to put strong crank on?? dont know as never owned a yamaha before
It depends on what 70 kit you intend to use, I did for peace of mind with my streetrace cos it revs higher than the other sports kits.
Mate with any 70cc kits u will need a stronger crank with the standard crank It may brake then your 70cc may be fucked
my old skool piaggio zip lasted ages with with 70cc kit standard crank, doppler s3r exhaust was still running when sold her
Really lol I my self a neos 8 weeks about they are good little bike put the little fucker who had it befor me raged it
Well you can pick an engine up off eBay for a ton should all go wrong bud, go for it you only live once
It shall most likely go boom after a while but will be incredibly good fun up to that point Go for it!
dudes.... in all the years i do this hobby i didn't saw a standard crankshaft broken from a normal 70cc cilinder.... in 99% of the cases your bearings will make noise and the cage will breake ( witch can also couse a lot of damage for sure ) A racing crank is better for 2 things, 1 it can take higher rpm's without getting viberating, and a higher engine pressure down in the carter, but that is something more for high power engines. Its always the bearings what will break. WIth a good fuel/air and oil adjustment it won't couse big problems. maybe on a longer period, but befor u reach that ur bearings are finished already. I drove myself with a standard crank on a Top performance due+ with hpi and all the shitt on it. If a standard crank would break, it would have done then @Tigger87peds, a minarelli crank and piaggio crank is quite a difference. The piaggio cranks are wayyy stronger than the minarelli's Think about the fact that a minarelli engine is a 20 year old concept engine without getting any upgreads... Piaggio did upgread the engine from time to time. better variomatig and poulies, bigger carburattor etcetc. That it is better and safer to place a racing crank is true, but if u fuck it up while placing u will drive ur engine in less than 500km to heaven. won't take any difference....
