Reassembling engine reusing rings

Hello,

I'm putting back together and engine that ingested a bit of Amal carb slide. The bit of Amal slide was beaten into a little ball. There's some dings on the combustion chamber and top of the piston crown, , but mostly I think they're ok, I'm going to take off some of the ones that could be considered burrs.

I pulled off the jugs to see if the rings were being squeezed in their grooves, but they seem to be okay.. This engine is getting near time to need a rebore, I think, but my money is a bit tight.

I was thinking about just putting it together to ride for the summer then rebuilding it this winter. I've always heard not to reuse rings, but I'm not really doing a rebuild. I can't see any difference in reassembling an engine with old rings and just running the bike for, say, 5,000 more miles. Do racers put new rings every time they take the jugs off?

I re-used the rings when I took mine apart mostly to paint the barrels at about 7K. I did very lightly hone the cylinder walls. I don't know if it's wrong to do or not, but it worked for me, I went on to about 13K like that before I rebuild the whole shebang. Just my experience, not a trained mechanic's opinion. No troubles with burning oil either.

My 1st pre-Peel Combat lost a thumb nail piece of slide before I'd gotten 'it' and only discovered a year later after deciding to fix the leaks and smoking but for sure not anything to do with lack of power or anything else at all, even 87 octane in summer heats. Chambers were pecked up like ice pick attack and valve lips beat up to curl off seat and seat nicked too. Sand smooth out the high points in surfaces and if rings still got less than .016" gap should work a treat till time to break down and face the inevitable. What causes ring smoke ain't the gap its the ring sharp edges getting worn to a radius. Big ring gap mostly gives blow by leaks out seams more the out exhaust.

[album][/album]I would think that as long as the rings have not been relocated and remove from the pistons, then you should be fine. I would not hone either.

Although new rings won't break the bank, the cylinders should be honed and a break in/run in procedure followed.

What pvisseriii said. I agree.

My bud Wes has some grit inhaling issues so has re ringed like every couple year for over a decade and does not hone just new rings which seal as expected smokeless till grit does in but got wiser after this years ring job and put a thick layer of UNI air filter foam around the decorative cute racer special KN filer fake.
I say save the bores don't hone unless evidence of scoring and spend a couple cases of good beer worth on new rings now while easy and at hand. INstall Dry Rings but can wd40 and might even call TotalSeal Rings and beg a bag of their cheap version of Bon Ami for even better chance of getting away almost scott free and smokeless. Start it and go over 2500 rpm blipping for a min or so and should be pretty much done but for some road finishing.
