Today I added a2012 rxpx to the family. Well its mostly for my teenage boys, I prefer more comfort. My son was riding today and he noticed a slight surging as he was ripping along. Nothing big but it wouldn't hold one speed. I didn't know if that was normal when its in BEAST mode. The ski has 85 hours on it. Runs strong .So I was thinking : simple maybe plugs ,maybe fuel injector super charger etc . Looking for opinions.:thumbsup:

Start with plugs. I had a dead spot feeling in the throttle when hardly pulling it. Replaced plugs what book called for and took care of the problem and noticed better overall throttle response.

Ok I pulled the plugs out today and two of the three electrodes a piece was missing . I don't know if someone dropped the plug ,if it burned up etc. I'm thinking I should do a compression test.
