Not sure what is up with these shoes. With 70cc decently tuned, these will not engage properly at a reasonable RPM (with 2 shoe clutch). They rev high enough to overheat and crack the shoe material. Am I doing something wrong with them? I believe they are far too light at 75g+/-. Are they for stockish 50cc or 3 shoe clutch only?
I use red stock shoes shaved to 83.1g and have a beautiful and reliable slip-grab combo with Type F or Dex VI, right where it needs to grab-n-go.
Remove those potentially destructive pins if you do get these.
Tried Dex VI, Mercon V, III/Mercon, ATF+4 and type F. None of them get these shoes to perform correctly. Springs loosened or tightened; stock or blue; won't engage properly (again, in a 2 shoe clutch).
Maybe in a 3 shoe clutch, there would be overall more grab, so these may work right?

The pair I received were just under 76gr and balanced out to around 75.75gr each (with pins). The pins came loose/out really easily by hand so I lock-tighted them in. Stock e50 with estoril; stock springs set at 12.5 lbs (or one and a half turns in from flush) slipping till about 15-20mph/4500RPM on type F.

i bought two of these for a clutch mod on my Two shoe, and they came at about 73g per shoe. My stock shoe weighs 93g, so be aware before you start taking material off to further lighten and balance.

ok so i have these setup in e50 gila 3 shoe atomic clutch.. i burned through the first set cus i was using kickstart springs.. then the second set crumbled.. so i backed off way way far on the blue springs where the screw is almost flush with the arm.. now no problems.. not amazing take off but no crumbles.. also you need to file the ridge down on the pad to make it concentric to the bell.. overall they work and are cheep
