ring end gap range
hey folks,
so was gapping my rings as per wiseco instructions... needed to bring them to .015, top and bottom rings
first time grinding with appropriate tool and opened one of the rings a bit too much at .018
...am i safe, or should i just get another set and do it again?
thanks, paul

Actually, I'd say the opposite: put it in the back cylinder, since it runs hotter - the ring will expand more and close that gap more

I'd say put the wide ring on the bottom, might just keep a less carbon from getting to it, let the smaller gap ring deal with the direct compression. I'd side with the back cylinder comment, too; no need to give it extra cooling, won't be binding for sure. While perfect is good, it's better to be on the loose side than too tight. Here's a nice tutorial for putting it all back together, and gaping the rings, might have some tips you haven't heard of:

well, i ordered another set anyway...they were inexpensive enough
and yes, that nrhs info is great!.... i bookmarked it long ago and followed their directions when i did my first build...the only thing i didn't do was muck up the piston and walls with that redline engine lube...but think i'll do it this time

Three thousands. Ya thats the end of your world.
Really it is NOT going to make a difference. Put her together and move on to more pressing issues...

17 was always my magic # put the small one (large gap) on the bottom. and you do know to alternate the gap 180 on the wristpin?
You did hone and cut the ridge right?
