Here is Harescrambles K&N filter, Mr. Maintenance, a great example why you NEED a pre filter setup.

I wonder if anything has been getting past the filter?

Yup, didnt see that one coming did you, hey you know "the dirtier the filter gets the better it filters" K&N filters are good for ON-road applications or you better have a serious prefilter setup.

I stuck the camera right in the air box and started taking pictures here is the as found.

Here is the stuff he is collecting in the bottom of the air box.

Their is a simple fix for all this ------------->>> http://pilotodyssey.com/prefilter3.htm

Many others have done it, you guys sound off and post the pictures of your pre filter setup to inspire Hare to get up to the new standard...

the sad part is Pnut already GAVE me a killer set up. Guess i will use it on my other pilot.




give me a parts list or order whats needed and let me know

We can see why this buggy is at the pro shop. Keep the pictures coming !!! Learn from my shortcomings


Thanks to You Hoser

Here is some more...

Time to get serious about this project!

I need full access to the wire harness so we can resolve this fan issue, I removed the radiator plastic, the radiator is all bent up on top.. Cap smashed and the neck/top of radiator bent up.

Coolant leak by carb?

Look at the rubber on the choke cable, have you checked yours today? If not go check it, old rubber don't SEAL, this would be a good time for you to go put a dab of silicone sealer around yours even if it looks good!

Unscrew the choke to remove it and it wont move, dirt and shit packed above the choke plunger!

STOCK reed cage with CF reed petals

Upper left corner of the reed petal broke off, needs new reed petals.

Seeing all the shit the K&N filter let by its time to look at the cylinder

Its hard to see in the pics but I can see plenty of scuffing on the cylinder wall, the cylinder must be pulled for inspection.

Cylinder off, the bottom end seems clean and tight.

You can see where the "more flow" of the K&N really comes into play in these next pics, see the dirt scuffing on the piston skirt?

The head, looks like it needs a good lapping.

Hose connection on the head bent in bad, enough to cause a serious flow restriction, I have straighten 3-4 of these in the past with good success.

Murphys law, that's aluminum! you can straighten a bunch of them then one will break

Its still usable their is still plenty of surface area for the hose and clamp to hold/seal.. Still pisses me off it broke!

Either way the problem needed corrected.

The next series of pics are the as found cylinder pics.

Cylinder after lite hone with a AN-112 Sunnen ridged stone hone not a flex hone or ball hone

The cylinder measures 3.209
The piston measures 3.196

Do the math .013 clearance...

Just like I have found every COMET 102C clutch...

Anybody know how to service these?

Every snowmobile I have ever owned that came with a 102C all looked the same, I bought rollers and arms for one the others I just sprayed with lube and ran them as is, I didnt put enough miles on a sled to justify doing any more....

Its a endless cycle with this type clutch, use it, its gets warm, then as it cools it attracts moisture to all the moving parts, then it rust, sometimes the rust is so slight you cant really see it, then you use it again and it wears the rust off, then cools down again and attracts more moisture, endless cycle, this is what the COMET 102C queers don't tell you as they try to sell them to you.

My findings on the sleds I have owned with a COMET 102C and 108C was performance goes way down soon as you get a little play (WEAR -RUST) in the parts so its pointless to have a fancy smancy over priced clutch you can adjust every way from Sunday....

Hare -PM cafercr he makes a great dual air inlet mount for Pilots that's bolts onto stock air inlet mounts, I have a dual air inlet lid I'll send you-Pnut sent you the filters right?I am going to do the same set-up on Pilotnuts old Pilot in 09.

I'm sure if you left your power bloc out in the elements for years, uncoverd, open to the elements, it would look much like that comet does. That is not normal wear by any means. As you probably remember from our previous debates on these that I am familiar with these. I have made up a couple tools to aid in disassembly and would be willing to go through this unit and see if it is salvagable. You can pm me and I'll give you my adress to ship it to, if you would like.

Like all moving parts, friction will cause wear and require maintaince. I have worn the slider buttons on mine but have not really noticed any performance issues with trail riding. Most performance issues are due to incorrect clutching from day one. (yes binding bushings and arms will cause performance issues, but is usually drastic) I usaully wear out the faces (where the belt rides) on mine.

Crank end play
