got here Total Seal Home and click on TRILOGY OF THE RINGS By Steve Dulcich it shows how they work . it not really a gapless its 2 rings that fit together and make a gapless seal
Old idea.

This picture is from the May, 1916 issue of "Gas Power" magazine. The ad touts Trump Multiple Piston Rings. It's hard to see in the picture, however, the three rings shown are "keyed" together to form one ring. Again, this is in a 1916 magazine. That was the year that a Model T Ford did not have brass headlights.
For some narrow applications the gapless rings have a place. Don't waste your time and money.

Old idea yes, but you don't think it's still being done to this day? Check out the link provided above. Total Seal makes gapless ring setups for automotive use. And I've heard of other manufactures doing the same thing, although Total Seal is probably the most popular. I have heard that it works, and works well. I don't see why it would be any different on a small motor than on a large one. I mean, rings are not too expensive, and higher compression equals more horsepower. So the dollar to hp ratio might be worth it? No worry wasting time and money here.. hehe. It would be a lot for me to just remove the governer on my 6.5.
A guy can focus on tires and setup IMHO and make a big difference in an old mini that has been down the road a ways.
The tires, especially the front, cannot be square edged. Forget the gapless...spend far fewer bucks on tires and get a far greater reword in performance. Far too many are "handtruck tires".
The steering head on most are worn out. The bolt is usually not even bushed. Drilling out and installing tight fitting bushings and a new bolt may be difficult but a heck of a lot less loot that high zoot rings.
Bent frames and forks are all over the place. Evil handling will always be the result. Putting the frame and fork assembly on the bench and useing squares and levels and plumb bobs to locate the things that are wrong, and then correcting them, will be time consumeing and not much fun but will yeald a minibike that is far safer and handles a lot better.
Ya can't make a silk purse out of a sow's ear but you can do some chassis tuning that will improve things.
