Shell V Power Fuel

Question to anyone? I have A 2005 Summit X 800 with 2300 kms. I've had it from brand new. 99% of the fuel I've used in it is Shell V power. Last week I change the rubber boots between the carbs. and cylinders because the rubber was deteriorating from the inside out. Has any one else had thes problem?

Common Problem

If you go to snowest alot of people are having the same issues. I have V-force reeds in mine to get away from this issue. Another thing they are always complaining about with the 05 is the exhaust manifold bolts come loose and the oil pump cable doesnt retact so it over-injects oil. Just a heads up.
