I currently own a rampage extreme and am looking to up grade to a mighty mini with 3 valve 125cc engine. My brother has a mighty mini already and the problem is the 3 valve engine seems very fluffy at low revs and bogs down but pulls hard after the fluffy part. it is very annoying and was wondering if anyone knows of a cure before i part with my cash as seems a very good bike. cheers for any help.
