About 8-10 guys from my area just got them(110cc,more than likely not the same brand, but same style) they're have a heap of fun, but found they are very high maintainence.
Some of the probs
-Front disc prone to damage when racing off road.
-When the chain jams on the front sproket it damages the everthing aroud the jam, a few of them had to get new motors cause it damaged the engine casing. Leep chain tensioned and lubed up correctly.
-Tyres, cause theyre a heap of fun(like PB's) you'll end going threw quite a few sliding the corners etc.
-a couple found the gearing wrong for their needs, 1st gear revs out to quick(approx 10km/h max). But easily fixed with new rear cog.
Mods a couple have already done.
-Bigger carby.
-1 Just bought a titanium exhaust($600 no joke) for one, no real power improvement, but good wank factor)
-they're buying slick/road tyres to race Mini Motard style racing with us PB guys(in their own class).
-minor port and polishing.
-125cc bore kit.
-"For big power, go the side saddles and reflective vest from Australia post" Joke i have going with a mate with 1 as they use a posty bike style 110cc motor.
Well have fun. I dont care if its car, bike, boat or goat. As long as your happy with what you ride. :wink:
