So with 28T pulley, any problem if I use with a tyre split of 7mm? Thks
The only problem you can face is going into a corner offthrottle. The tire split will cause friction between front and rear and mostly the rear will become more loose.
You just have to give it a try to see what it does. As mentioned the smaller pulley is most of the time the better choice on very small tracks with tight corners.
