Artic Cat 90, goes slow, help

[insurancepi]

I just purchased a lightly used artic cat 90 (not the race version) and I unscrewed the governor all the way and the atv will only go 15 mph, is that normal and what can I do to get it to go faster. A friend of mine has a Polaris 90 for his son and that thing will go 30 mph and all he did is unscrew the governor. Is the artic cat youth model just slow or what?[img]i/expressions/face-icon-small-confused.gif[/img]

there is a spacer in the primary clutch that can be removed. you can also try going down a tooth on the rear sprocket
