For those of you running these wheels, has anyone had any rail or track issues? Also how do you machine the mount and where, a picture would be helpful if anyone has one showing this. I want to put on the Skidoo wheels and the Fix extra wheel kit and new hyfax. Does anyone see a problem running the Fix wheels with the Skidoo wheeels? I would try only the Skidoo wheels first but I have an Attak and the span between the front and rear wheels is too far.
