[QUOTE="helio lucas, post: 1390678, member: 78346"] frascati, i do think it´s not the better idea to put a kx80 engine in that puch frame for the simple reason you could make it simple... a kx100 engine is more long term reliable than a 80 because has smaller ports (compared to the bore) and has more potencial for silencing, power ,torque or power delivery wich means even if you do not get it rigth the 25% more cc will make the difference. now, fuel consumption is a problem with such a small tank, a chinese pit bike engine is a great engine for the purpose. there are from 50cc to 170cc horizontal cilinder like the original engine wich will make it more stealth. they are very litlle stressed four stroke engines so reliability is not a problem. fuel comsumption is maybe half than with the kx engine. power delivery is perfect for the aplication. peak power is more than suficient. if you think a 50 cc engine will not bring anything more than stock setup, get a 125-150cc lifan (zongsheng or any other good source) engine. they have some 10-15hp with loads of torque. they don´t need a bulky exhaust pipe like a 2st engine and they can be bought for very cheap. in portugal a kx80 worth twicw the price of new pit bike engine. just one more idea: stock engine could be modified for maybe half the time and money than to get that kx80 engine working. in netherlands, austria and india they have a pretty good source of information.
