is that aluminum on the plug in the bottom picture on the right?? are the 2 pictures of the same plugs?? Maybe my computer isnt showing the pics good,,, it almost looks like the 2 pics are of different sets of plugs.
Yeah I'm not sure what to say except there is nothing good going on with those plugs. I'm doubtful that the problem is just oil consumption, unless it's more than 20:1. I have run the EXT Special (unintentionally) at 24:1 for several trips and my plugs didn't look nearly that charred. Maybe if you're using cheap oil that could make it worse, I was using Interceptor. The carbs were also set up slightly rich for my altitude as well, still not that black. And yes, it does look like flecks of aluminum in there. It could be a trick of the flash, but it stood out at me right away. I hate to sound the alarm, but I would at least do a compression test. I don't see how an EFI sled with full compression could ever have plugs that black. Unless they are the wrong plugs for your model. You might want to check that too. One of your sensors in the EFI system could also be bad. Check the trouble codes in the computer.
I believe the oil pump on this sled is not ran through the efi system. It should be hooked directly to the throttle cable and the more you pull it the more oil you get. Its based on your cable set up.
You could have something pretty easy like the throttle cable running to the oil pump is pulled somewhere and your throwing in too much oil that way. Have you put handlebar risors on the sled?? Could also be a faulty oil pump.
Looks like you need to make an oil pump adjustment. Every one ive owned needed to be turned down. Pig rich from the factory. First you need to find out your ratio. Try to get it as close to 50 / 1 as you can. If you want to check, follow the cable down to the pump. With the throttle pinned open, there is a hash mark on the pump arm and pump housing that should line up. This will give you a starting point when it comes time to adjust. I usually ended up about an 1/16 to 1/8 shy of lining the marks up to get it where it needed to be. Good luck.
Pic's are of the same plug's.....nothing shiny it just a trick from the flash. Compression is fine.
I do use WAY to much oil. Never figured ratio last year. This is causeing all kinds of issue's for my APV's. cleaning every 100 miles, there stuck at 200 miles.
I have ran Amsoil injector oil and the interceptor......Cat APV oil.....Ski-doo power valve formual.....Klots synetic sled oil.....NOTHING HELP'S. I would say I used 6-8 GALLONS last year in like 1000 mile's.....might have used more,had to buy at a few gas station's as well.
I don't think I have ever seen a sled smoke this much.....as far as the oil pump,it linkage driven off the t-body shaft. The handel bar's have never been off. I did check the oil pump setting's last year and the WOT mark was on.
Some one said it could be a sensor.......How do I pull code's,I know where the SES light is(back of ECU) I know it's not on though...checked that last year.
I will say I'm a hard rider,I seem to run this thing hard,I spent most of the time hard on the gas.....and most of the time the trail's arn't groomed so the snow is loose and the sled is boggy.
Oil cunsumpsion. You said you use a ton of oil. Power valves gummed up after only 200 miles. I dont think a sensor will have anything to do with that. The hash marks arnt gossiple and i always ended up a 1/16 to an 1/8th before they lined up just to get close to 50 to 1 ratio. Also, the better quality the oil (thinner, full syn, colder pour point) the faster it will run through the pump. Just need to figure out the ratio and adjust accordingly.
Youve got it. Sounds just like youve got a thirsty pump. I had one so bad that i had to bend the cable bracket down to get it where it needed to be. Ran out of adjustment. On the linkage style,if it happens to pop off the pump, I think they go to full open. Worth a look.
My thought right now is you have something faulty going on inside the oil pump. I know that the pump is driven off the t-body, but your throttle cable is the on off switch for the pump (easy way to understand it).
Start with the simple stuff, make sure you dont have a faulty cable, or bent rod,,,, check ebay daily for an oil pump. You may hit one pretty cheap. If you get one cheap, jump on it and swap them. Could solve the problem,,, keep us updated on what you find
A few years back I had the same problem with one of my T-cats. I found out that when your oil pump fails it is usually in the open position and lets a ton of oil through no matter how you adjust it. Replacment might be necessary.
