I pulled my plugs after a 20 minute ride at approx -4 --5 Celcius and they look a lil wet and dark black .

I figured with DPM the plugs would look light brown or brown at least.I have oil set to factory setting and not hanging up,sled runs good,good compression ect.So i pulled the DPM Solenoid and checked with 12 volt and tit clicks everytime,al hoses are good,no wear or pin holes.It there something else that has to be checked on PSM and if so how do u do it.Thx ps: i did read that there are some thing that look like main jets in it that need cleaning,are they under the Solenoid or does that cap on the end off the PSM body have to come off.

I also have stock jetting.Sled runs ,idles and performs good.

Your orings could be shot on the float in the carbs. I would try replacing them first. I believe the only check for the dpm is to hear it clicking. It sounds like oil to me though, have you figured out your ratio?
