i still never have messed with the oem clutching on the kids mxu 150...i have been told to go lighted on the weights for better acceleration...i will never put taller tires on it,but obviously any decent tire weighs more than oem,lol...so,does anyone know what the oem roller weights weigh in at?
or,does anyone have any new suggestions for me?
thanks

I would start by cross referencing the OEM variator part # with other 150cc Kymco scoots. This will give you an idea of the roller size. (18x16mm ect.) During that search you will most likely see the stock rollers, and their weight. Dr. pulley sliders seem to work better than rollers in some applications, and I believe this is one of them. They give a taller top end gear, as well as better take off. I would suggest 1gr. Heavier on sliders as they do increase rpm's by their nature. If you stick with rollers try 2gr lighter, and that will give great take off/ increased rpm's throught/ and hopefully keep your top end as is.
A Control or torsion spring in the clutch will also bring up the rpms, and hold the gear ratio lower till it tops out. Combined you will think you have a different bike. For the spring a 1000 is fine for a stock bike, and a 1500 is better if you have any mods at all (rollers/sliders). Any of the online parts lists will have the #'s you need.

I found them. You can read them. It's in here somewhere... Or call one of the shops in the links. It's not always easy

hey zombie...thanks,most of those are my past posts and they never do give any clue as to what the oem weights are and oem clutch spring specs...i did get a stiffer spring from epi...still though,i have no idea what the specs are as it was a discontinued spring they just happened to have 3 left of
the 1st link of yers is very helpful though,hopefully scootermike is still around to get a hold of since he hasn't been logged in for 2 years,lol...it is great to finally know that the motor is the same in the scooters though,that will help

Any time... You would think some of this info had TOP SECRET written in Tai. Mostly cross referencing #'s on the parts lists gets it. Even MOST dealers don't know
