The work begins
« on: May 28, 2018, 07:14:12 AM »

Like my user name, at Longlast I'm starting to get ready for striping the motor down to repair/replace the bottom cylinder gasket leakage. Thanks to those that helped me along in the previous post when I had questions on this.

Got the parts and tools I didn't have to do the job. Haven't got the rings as yet not sure of the ring size. I order them after I take some measurements.
I'll post as I go along.

Are you planing on doing any other work while you have the motor open?
Make sure you check the crank run-out while you have it open.

Not sure how that's done on a Harley, plus don't have a micrometer gauge.

Motor was running good no issues then stalling out sometimes coming to a stop.

Will look into it.  :2vrolijk_21:

If it had good compression not using oil leave the rings alone. That ring set will cost you as much as new pistons and to be honest is not likely needed. Fixed hone may take a thou or more to get the cylinders true and now the piston fit is gone. Bal honing not something to do with the thin low tension rings. If needed due to oil consumption or compression loss then bore to the next OS. Now you have seasoned cylinders bored and honed in torque plates (hopefully, it is a must for good ring seal).

Compression 120 rear 125 front.  Oil consumption  good no smoke on cold start up  or hot.

I didn't think it would be acceptable to put the pots back on the old rings once removed as the rings would lose there seating then it would burn oil and have compression lose.
My thoughts were to recross hatch the cylinders and new rings,

120/125 sounds low. That needs to be 175-185 at least.

The cvo 110 has 210 or thereabouts with an open throttle and compression releases off. Check it properly with a quality gauge and it will be higher. If not you have issues and it is time to go +.010 or +.060 (113")

It is very acceptable to pull barrels and drop them right back on but you need good seal first. Reringing is a non starter with rhe low tension thin rings.

Squirt a little oil in the plug hole and re-test the compression. That will tell you straight away if the ring seal is
bad. If it's still low, try another gage.

It should also be checked with a little heat in the motor
