    Pump gas. I have heard of instances where race gas has caused trouble in KTM minis, so we run pump gas.

    Suspension 101

    Can anyone give me some suggestions on tuning the suspension on my son's KTM 65 & 85. Setting the sag is simple, but how can I read what the bike is doing, as he rides, to make sure the compression and rebound is where it needs to be?

    Cylinder Scored after Rebuild

    Looks like metal coming up from the bottom end. Maybe a circlip or some remains from the previous cylinder.
