Switching to 13 gram rollers really made a difference in acceleration, and without loss of top speed, which amazes me.
Just got me a set of 15g and some 13g sliders after reading your post. Also got a new OEM belt and I put it on with the 14g sliders that I already been using, and the OEM belt doesnt perform off the line like my Malossi belt did.
BUT the OEM did lower the rpm`s at highway speeds and gets me a whopping 72-75mpg, something the Malossi didnt do. So theres some data for my books, lol.
I just got a new Malossi belt which is a different style than the previous belt I got from them, and this one looks just like an OEM belt with the notches on both sides. I`m also going to order that previous style from Malossi which only has the notches on the inside of the belt and do some swap out combos with different sliders as well and compare.
This should be fun theres like 9 different combinations to try out and see all the differences
Edited to add that highway speeds for me are in the 60mph range as I do all my riding on country roads.
