Too much oil? Wet plugs

[snowracer21]

2016 Axys 800, ~1800 miles... running SLP pipe/silencer and 68g weights.. Pulled the plugs to check compression, which was ~132 both sides (@ 100' elevation/cold engine)

I'm running BR9ES, I've had problems before where after a good rip, I'll shut the sled down, (single digit temps) rest for 10-20mins, and go to start the sled and it won't start unless I pull it over 5-10 times while holding throttle wide open.

Anyways, pulled the plugs today, and noticed the plugs were wet, and quite a bit of oil both on the plugs, in the threads, and in the plug wells on the head. To my knowledge, the oil nut has never been messed with (bought the sled as a demo, called dealer and they said they never touched the oil feed nut)

Always ran Polaris VES Gold, & Shell 92oct.

Also, I've noticed my sled REALLY drinks the oil, like, at a WAY faster rate than it did on my 2015 Pro...

Should I possibly turn the oil screw down a slight amount? I know how fragile these engines are, so I don't want to do anything drastic.

Also, are the BR9ES the best plugs for these engines, or should I go with something a bit hotter?

Theres no adjustment on the new 800 ho. The oil pump is electronically controlled by the ecu. And I bet its extra fuel making the plugs wet, not oil. TPS may be out of adjustment that's why its hard to start.

10-4, Sled is still in warranty... think I should take it in? Also, it's def oil on the plugs...

Pretty sure they will charge you labour for doing a TPS adjustment. There is a thread here on snowest on how to do it yourself.

If you are running a BR9ES this could be your problem. The correct plug would be a BPR9ES. The difference is the latter has a extended tip.

IIRC; The '16's were prone to fuel flooding issues in cold temps. Similar symptomes at least to your having to pull it over too many times when warm. The stop gap was to apply partial throttle from the first pull (like the old carb'd sleds).

If it did not lite off. Hold the throttle wide open (stops the ECU from adding more fuel when not running), pull it over until it cleans out and lite off.


A re-flash of the ECU was supposed to help with this, but some have said they lost power (read de-tuned) after the flash.

FWIW

my bad, they are BPR9ES
