Thinner? The top 2 rings on both the 11.25:1 piston and stock piston are identical. its the oil ring on the 11.25:1 piston that's thicker and wider then the others. 4mm thickness vs 2mm and .128in width vs .160in

Actually the 9.1 and 10.5 compression pistone use the 1.2/1.5/4.0 rings and the 11.25 uses the 1.2/1.5/2.0 rings. I just went through all of this last week as I re-ringed a fellas XRL that has a JE piston in it. Ended up buying two sets of rings because of the web site. The JE site is WRONG. Where did we ever hear this from before???

The bike I worked on has a JE piston that has 102 JE cast into the bottom of the piston but it measures 101mm !!!!!
I needed a set of rings so at first I grabbed my new JE 102 piston that I got from CW only to find that JE included a totally WRONG ring pack. Not even close to correct. Multiple calls to CW and him to JE finally resulted with CW sending me a proper set of 102 rings and me returning the incorrect rings to CW.

What am I Missing?

Well, I finally got some time to trouble shoot my No Spark Issue...

1-replaced the cdi = no spark
2-check coil primary = reads .2
3-check secondary coil = reads 9.3
4-check pulse generator = .500 (the manual says 423-517) hhhmmm?
5-clutch assy wires = modded by a previous owner (the two wires are spliced together)
6- check side stand switch = continuity when up/down=no
7-kill switch- took it a part and cleaned it. Dialectic grease was/is present and I roughed up the contacts as much as possible. It looks to be functioning as designed.

Have I missed something? If not I guess a complete wiring Harness is next huh?

Replace the handle bar start switch assy. It's not the kill, on/off portion of the switch it's the red start button that you can't get in to. My bike was giving me no start headaches and I hosed both the on/off and start button with electrial cleaner and all is well now. I will eventually buy a new switch assy. Or just for shitz replace the pulse generator. This is my guess from many miles away.

Did your on/off switch show to be working properly with a meter? Mine does....

I never bothered to check it with a meter. I just hosed it out with cleaner and it's been working fine since.

I'd throw my dart at the PG

BTW... Have you had the parts off of the crank shaft on the clutch side?

I'm thinking the same thing. The manual says to look for 423-517. My reads .500 I'm guessing it's not a typo in the manual. lol Lord I wish I could lol about now..

Went through the same issue a few months ago.....the 11.25:1 oil rings are 4mm wide due to a wider spacer.,the 10.5:1 ring set uses a 2mm oil ring spacer...........i ordered for a 10.5:1 piston and the oil ring set was too narrow..........CW sent me a 11.25:1 piston is why.........and the oil ringet is wider on the 11.25:1 piston..

Booooooogus. I think there is a thread here on ADVrider showing the holes you can clearly see through the metal mesh, compared to paper filters. They are probably better than no filter at all but oil filters are made to collect stuff and be thrown out. Not a good area to try to save a buck in my opinion because it'll just cost you more in the long run. Besides, you don't need to clean a paper filter- just replace it.

Reusable Oil Filters

For the life of me I have never been able to figure out what the deal is with reusable oil filters. Yeah they sure look neat being made of stainless steel but HOW IN THE HELL DO YOU CLEAN ONE??? Take it to your dentist and drop it in his ultrasonic cleaner???
