I was wondering if anyone here tried the totalseal gapless irngs on their 426? Ive had great succes using htem on my 2 strokes with power increases of 5-8% (3-5HP) all across the rev range on back-to-back dynomometer tests. they seem to increase bottom end, and bottom to mid transition DRAMATICLY! and they also helped when revving real hard and on hard charges when torqueing through gears uphill. anyone used these rings ont heir 4 stroke? I just wanted to see before i baught a set of them from totalseal for my 426f!
