I have a 2001 arctic cat dvx 90. The engine has low compression and I am trying to find a top end rebuild kit for it. Anyone know if they sell them and if so where?

 

Are you kidding? Your AC dealer has (can order) the parts you need and they are only about $150. Get it fixed so your child can have fun too.
BTW don't use boat 2-stroke oil or you will be rebuilding it again. TCW-3 oil is for Two-Cycle-Water cooled engines, TC oil is for Air Cooled engines like your 90 and most other small 2-stroke engines.

 

I do not see aftermarket kits for the dvx90 online. You will probably need to call a dealer and have them look in thier shop manual, or on the computer, and print a list of the parts/gaskets needed for a top end rebuild on the dvx90. They have a book that has a standard list of how long it takes the technician to do the work and a list of required gaskets/parts. You may also need addition parts such as new valves, guides, etc that are not on the list.
