Anodized. Besides mentioned in the XRL thread, the detail is the other give away on the top. Powdercoating "blurs" the details.

thats EXACTLY what my first thought was...

the worst case scenario is a loose valve seat OR bent valves...timing is good though...since I just reinstalled my oem cam and rocker set.

thanks for the help I will let you guys know as soon as SEMANA SANTA or holy week is over

holy week means beer week down here! jajaja

Valve rotation is not an uncommon occurrence, but one revolution every 20 seconds is extreme for idle speed.

Im going to try to mist the intake since this all happened after a ride with low quality 87 gas down here, thats all I could find...of course the bike handled it fine but with the hrc cam and whatnot maybe I carboned it up way to much and now my seats and head are all carboned up and therefore not sealing 100 percent of the time..

just me thinking out loud here. I really dont want to tear the engine down again for craps sake...especially since my rocker cover does NOT leak now jajaja

so

water intale throttle fun coming soon1 jajaja

if it improves just a bit then I know I can try some seafoam or similar stuff and run some super high octane gas and boost

maybe just maybe it will clean it up

I DOUBT IT THOUGH JAJAJAJAJAJA:ro fl

Compressing piston rings

Evening all

I'm having a bit of trouble compressing the piston rings . I've got a ring compressor , the sort that has a square key on the side to ratchet it up . For "small engines" with a piston size of between 53 mm & 125mm

Am I right in thinking that the new piston is fitted to the rod , then the barrel is slid over it ? ( with compressor in place ?? ) If so , how do I remove the compressor ?

You tube vids show the piston and rod being dropped into place together during a full rebuild process ( admittedly for a car rebuild )

I've had a look at Steve's excellent rebuild thread http://www.advrider.com/forums/showthread.php?t=713831 ( which inspired me to have a go at this myself ) but I can't work out how to get the tool off , or to be honest , how to get the rings into the barrel with the tool in place

Cheers , Stu

Any help greatly appreciated

here is what has worked for me, and I dont use any special tools just patience beleive it or not

1. drink a nice cold beer
2. clean barrel nicely
3. do not oil anything but the piston skirt bottoms, I have become a huge fan of dry fitting a pistion and rings now after seing those nice japanese fellows man dangle and install xr600 pistin dry as well you know on youtube vids, sekei something they are called.
4. install piston with all rings on rod...lube pin rod
5. jack the rod on both sides with some wood and balance the piston bottooms on it so the piston and rod combo stands alone by itself
6. with completely dry barrel and gasket installed I have luck by compressing the rings individually while jiggling back and forth from front to back. I have small fingers so I can usually feel the ring ends or gaps and thats where I compress, then I push down on barrel a bit, then compress mid riungs, the do the same till you get to the top ring.

I also break in the engine with a lot of engine compression DOWNHILL and nic long streteches of proggresive throttle

this method works great. I had a bad experience on my first rebuild and over oiling everything and among other things I had bad sealing rings that never did their job...

cheers

yeah oil does NOT help with the hand install

if you dont want clean all oil you can also simply use metal zipties the thicker the better and loosely compress them like steve shows, you install over rings overlapping in a sense loosely then you install barrel over rings and ziptie(Im brain farting here, metal clamp or 2 is what I mean) and then you push down on barrel top firmly and more often than not you go straight in}


MAN DOES THIS SOUND LIKE SEX OR WHAT? jajaja

sorry

Jubilee clips ??

By overlapping , do you mean a bit of the ring sticking out of the top ( of whatever works to compress it ? ) . They're 1.2mm & 1.5mm wide , not sure if my eyes are up to that

Looking back at Steve's thread , I omitted to check the ring gaps , now I'm worried that the rings are too big / or the gap's not big enough . It's a JE Piston , btw

Cheers , Stu

Put each ring in the cylinder by itself and slide the piton in to square the ring up in the cylinder. Remove the piston , leaving the ring. Now measure the end gap.
