One ring or two?

[mpfine]

Would I be risking some level of cylinder or other damage if I ran my Jog 50cc on one ring? If I can get away with it for a bit, which slot should I put the one ring in? Upper or lower?

It could be done. It was discussed here in depth quite a long time ago, but I can't seem to dig that up ATM. The ring would go in the slot nearest the crown. You'd likely lose some low end power from poor sealing and possibly gain a little at high RPM from less frictional losses. The open space where the 2nd ring should be could cause some short circuiting. Accelerated wear would be expected. It's something that I'd only try for racing/performance experimentation or in an "emergency" when I had no other choice.

Thank you. Good points. I'll work on being patient. I don't want to cost myself more than necessary.
