    I used to use Total Seal in my old fule bike but had some `grooving' problems in the barrels around the top ring at TDC. However, many swear by them.

    I had the exact same issue when I used them in my Blown Camaro.

    Being a Mechanical Engineer I have done a lot of research concerning gapless rings and

    after visiting the very impressiveTotal Seal factory and spending a lot of time speaking to their expert technical staff, I have decided to run gapless top rings in my 1327cc Suzuki for next years race season.

    I used them on my Kawi F/B, only the 2nd ring was gapless, it did help noticably on the catch can.

    In additon to the gapless, Total Seal also provides excellent conventional rings too, so they have a lot of options for us. It's a great company, very focused and driven by racing.

    Yes, you run gapless on 2nd for blown / turbo apps.

    Thanks for the info guys. Have motors apart,might try them and see if they hold up better than what's in them now.

    I switched to gapless rings on my low 9 second air cooled Kawasaki bracket bike 3 years ago. I was hoping totake offa tenth or so on my ET. I did not see any noticable difference on my time slip after going with the gapless rings. I went with the gapless top ring set for my normally aspirated application and had Total Seal do the laterial gas porting on the pistons as they recommended. The gapless rings drastically changed my air/fuel ratio due to the stronger intake signal produced by the gapless rings. Also, oil is able to be pulled down past my valve guides down on top of my pistons due to the stronger intake signal. I get a good puff of smoke out of my exhaust when I first start the bike, and when I first open the throttle for the burnout, and when I go up on the launch limiter. My valve guides and seals are in good shape. Onthe plus side, after two full seasons, my cold leak down is still less than 5% per cylinder. If you are planning to use them for a nitrous or turbo applicationit is recommended touse the gapless second ring set over the gapless top ring set. I hopethe next timeI pull the engine apart that I don't see the grooving that Ian spoke about in his previous post. If you decide to give them a try, expect to do some tuning to get your engine to run properly.Edited by: Todd Meyer
