Hi guy's,

I have two problems, hopefully someone will be able to help me out.
First one is, I brought some rear MF2 CVD's and tried to put them in my XXXt 2. But they are shorter and I can't fit the wheel spacers on? if I tighten up the wheel nut the pins rub on the bearings, so the wheel doesn't turn freely.
2nd problem is, I just put a new 13T double in, when I accelerate at full trottle from a stand still there is alot of clutch slippage.
The slipper is adjusted to what the manual says, should I just tighten it up more? is it going to damage anything if I do?

Thanks
