big bore kit?

hi all i have a yamaha aerox 2002 plate i am thinking about bore kitting it to a 70cc can anyone tell me if its worth doing because i already have a reinforced crank fitted to my bike but i want to know if people think this will last http://www.ebay.co.uk/itm/NEW-BIG-B...ycle_Parts&hash=item3372d0a516#ht_5029wt_1270 have a look and let me no wether its worth it

 

if your on a seriously tight budget i would reccomend a parmakit sport 70cc kit from pm tuning

very cheap kit and not bad quality at all

i only have 66 pound in my bank and what could go wrong with the ebay one?

 

the one on ebay will never match the quality of a malossi or even the paramakit kits that have been mentioned, you get what you pay for at the end of the day and if you want to compromise reliability for the sake of 30 odd quid then it will soon not be worth it, save up a bit more and buy a decent kit, youll end up buying 2 of the ebay kits money saved = 0. buy right buy once

 

yeah as said its the quality you have to think these parts have no warranty at all as soon as its been fit

its all over really just by looking at the piston it screams cheap. the ports are garunteed to have rough edges and its know that the cheap big bore kits have absolutely shit port timings so you dont really gain power

you will not regret waiting untill you have around a hundred quid as you will be able to get a kit that would actually have quality control checks
