    I use a 50/50 salt away mix for deep cleaning. I just fill the flush port directly with about a gallon of the mix and let it sit. After about 24hrs I flush it out. Works great for heavier build up....

    I always thought that the 230 charger is simply the revamped 260 charger. I’ve seen several who have swapped them to their 260 machines. From what I understand, they detuned the early model 230’s...

    There will always be a trade off. Let’s just get used to it, the carbon seals are here for the foreseeable future. Proper maintenance will avoid probably 95% of these issues.

    You could probably put me in group 2 but I am very cautious on how I build my skis and put reliability above performance. I ordered all new bolts only to find out that 4 of the new oem bolts would...

    But when you refer to carbon ring failures what are you saying is failing? The bellows or the actual carbon ring? If the bellow ripped apart then ok, yes, that’s a bad failure. Carbon seal grenades,...

    I also agree with the low speed handling not being so great. The nose dives and the foot wells fill up fast and make it easy to tip. Its just how these ski's ride. If you know what you dislike...

    They were all replaced with the 2008 model. You'll need to get the correct firmware for your ski and also use a candoo or take it to the dealer to marry it to the ecu. If no one chimes in, you can...

    Getting really tired of seeing these carbon seal posts. The bellows is like a rubber spring. If it heats up too much the bellow softens and no longer holds a tight seal against the hat. When it...

    Two things come to mind. First try removing and cleaning the iac valve thorougly. Second is to check your TPS outpu voltage at idle. It should be between 1.08 and 1.18v with a 4.75-5.25v input from...
