yo has anybody fitted a 50cc sport kit? im not looking to go to a 70cc on my vivacity as its just a run about i needs new cylinder and rings so was going to buy this http://www.pedparts.co.uk/product/1481/stage6-aluminium-50cc-cylinder-kit--peugeot-air-cooled also do these need to be worn in ike a 70cc kit? if so how long?
Why not 70 it? That kits basically mid-race its gonna give you all the downsides of a single ring kit (unreliability, having to upgrade everything first etc) and probs only slightly more power than a iron kit. They're only really of any use to people racing in under 70cc categories as far as I know. If you want economic get a polini sport, if you want to go fast get a sport pro but this is just like the worst of both world lol
i dont want to chuck money at the viacity as thats what my zips for i found this kit which is double ring http://www.pedparts.co.uk/product/1353/motoforce-50cc-plus-sports-cylinder-kit--peugeot-air-cooled
All it is really is a ported 50cc cylinder you could probably just do it on your cylinder you have now
