I just got a Magnum MKII which is in really really good condition.
It bogs up hills a little, and I checked and noticed the previous owner had drilled holes in the airbox. It might be running rich but I havent had the time to check the jet in the carb.
what range of jets are usual for a stock magnum, and what should I do about the airbox? I've electrical taped up the holes for now, it seems to run a little better
