qt50 70cc malossi cylinder ring gap

Rob LaFreniere /

I don't remember getting any instructions, Does Malossi list a gap range, or should I use method described here : https://www.mopedarmy.com/wiki/Ring_gap which gets me .180mm - .184mm.

thanks again.

The table is the best bet. Better to have slightly larger ring gap than too small.

I'd be surprised if you have to adjust it. Is this new cylinder, piston and rings? .18mm sounds right.

Yes all new, I hope. There are so many irregularities and burrs in and around the ports that I not sure how much faith I should put in the product. I couldn't find the qt50 kit listed in malossi's web store so I'm not really sure what I have. My guess is that Treats has stock piled them.

I checked, the gap was bigger than .05mm and smaller than .1mm. I tried sanding it down slowly but wound up something close to .4mm. so that sucks and necessitates buying a new ring,
