My 16 YO son was riding my Kodiak 400 and rolled it. The end result was the thumb throttle broken off. Is there any way to replsce just the thumb portion or do I have to buy an entire throttle assembly? Also as he was riding he crossed numerous streams and went through a lot of mud, now the machine has no power, I assume the belt is slipping; is there something else possibly wrong that I dont know about. He broke the throttle early in the ride and made do with the end of a bungee and some tape but the lack of power happened after he had been through water and mud.
I am looking to replace the belt, and fix the trottle before I give him some additional instruction on riding with the wheels on the ground.
Thanks

Make sure that your components are kleen from mud such as your airfilter and intake. a lack of air getting in can sometimes be the problem.
