has anyone ever tryed the athina 170cc top end kit on there bike. I was just looking at it and I cant help but wonder is it worth the price for example do you need a different carb or can it just be rejetted, is the flote bowl large enough and can it refill quickly enough to feed the engine, will flote hight need altering. can the gears handle the higher revs. will the oil pump need ajusting. if your on a cbt watch out for the law. mot's could be a problem.
after all this and a bit loose change of £400 and if you cant do the work yourself you have to pay someone to put it in would you go for it
