The malosi doesn't even work that well unless your kit is over 60cc the weights that are made for it suck
I have a modified stock one if your intrested. Shaved the brass fitting off and its all good but its a 6 roller set up. The 8 will give you better low and mid but the top will be the same.
I have a polini and weight wise there is tons of them way more than malossi.
Let me know if you want the stock one sldwys86@Hotmail.com
