Spark plug opinion

[fnDan]

Pulled the sled out of the trailer. Pulled the plugs and did a compression test. It's been sitting since last season and run enough to warm up to 120 and rode into the garage.<br>Compression is 120 and just below 120 tested cold.<br>Here's a couple of pics of the plugs. Too much oil? I've read that the oil can be adjusted slightly.

from everything i have read on snowwest the rmk 900 doesn't get enough oil and most pre-mix 100-1 in the tank. but i do agree it looks like it got too much oil or it's running rich are you running stock air box?

check the oil pump cable common to break & hang up causing full oil all the time.

Running the Timbersled intake.
I'll check the cable.
I've ordered a piston kit to rebuild the top end. 7800 km's so it's time.

That's a lot of k's good show . Like he said your oiler cableIs gummed up when u rebuild put a new cable on and add an extra spring. Use stock 06 pistons

FBF oil cable is the only way to go, I wouldn't be the least bit surprised if your stock cable is stuck on full. Every 900 I have delt with has had this issue. On a side note, my 9 goes through tones of oil as it is, even with the updated cable, every time I fill the tank I fill the reservoir.

For sure they do, mine 9 loves the stuff try FBF "Claude" in Calgary if not another company in the US make one as well, not sure if there as good as Claude makes.
