A complete 107CC upgrade kit for Honda Cub C70 and C90 engines - please note that with such a long production run Honda changed the engine over the years so it's important to study the photos and make sure this will fit your engine. In particular it's important to check the diameter of the small end bearing (gudgeon pin). This kit comes with a 14mm pin - some Honda engines used 13, be sure to check yours first. I tried the kit out on my mate's bike, it is a big improvement over the standard set up - add a larger carb, set the timing up and it transforms the engine. When they are gone they are gone so don't hang about.
