OK i have a few questions. First what type of things are hard on my motor..wheelies, donuts etc.? Another thing, are cobra pipes any good..i've heard their loud but do they put out any power? Are the universal e series pipes good? sorry so many quesions.

 

donuts are hard on the clutch until you get them going. cobra pipes suck , get a wight brothers e-series system or get a suppertrapp muffler with a CT racing head pipe.[img]i/expressions/face-icon-small-wink.gif[/img]

 

Cobra pipes suck!!!
The only thing donuts might hurt is that your bearings will wear faster and the tires will to.
wheelies? hmmmm.... I dont know if that will hurt anything.
Just keep up on the maintanence of your quad and it will last a long time!
