So I'm assembling the engine on my 80 SRX, I have oem yamaha single ring Pistons, new oem rings and fresh nik'd cylinders. I checked the installed end gap and it's at .011in and specified in my factory manual is 0.014in min and 0.022in max. What should I do? This is the first SRX I've restored. Appreciate the help.

.011? Take fine a file and put it in a vise, then take the ring and close the end gap on the file, and gently take off some ring.

Okay I wasn't sure if if was frowned upon to file end gap on sleds never had to before. Just wanted to ask before I assembled the whole thing and score everything all up. I appreciate it !

just make sure there are no burs on the cylinder side of the ring that you file... do it lightly to avoid this and you should be good.

Sounds great, appreciate the fast reply !
I would check your piston to cylinder wall clearance as well!

Okay sounds good I will ! They fit pretty nice in there. I actually had them Teflon coated at US Chrome so I need to fit/scotch areas on them anyways.
