All right, I finally found Ethanol free gas, bought 20 liters, and put it in my sled along with Star Tron Enzyme. Then I took it out for a test ride. (It idles better on start up now). I left the Ethanol wires unplugged, and it bogged on top end, and a slight bog in the mid range (just like last year). The only difference about it this year is that even with the wires plugged in it does the same thing (I haven't decided if the bog in the mid range is worse with the wires plugged in or not). The thing that has caught my attention this year is that there is snow getting into the engine compartment area, and even some in where the clutches are. Also, sometimes in the mid range, the sled goes, and holds back, goes then holds back. Could this whole bogging thing be caused by slipping clutches? I did a compresions test and both sides were @ 120 psi. Also, does anyone have a genious idea how to seal the hood better? Thanks so much in advance. Whenever my sled has a problem, I go mad!
