In 6+ decades of bike fiddling I've known about under cutting but don't know how common it has been over the years. Any clue as to what bikes have had it or not? I've always felt Suzuki & Yamaha trannies seemed better but didn't know why they were. The occasional missed shift doesn't bother too much but unintentional downshifting is a worry for us Golden Age riders. I wonder how much $ is saved w straight milling the dogs vs a small angle. Is this a problem for Ninjettes as they may be ridden w more gusto than others? Others have asked about power shifting but I think they'd avoid such if shown the resulting dog wear & tear. Anyone heard of XS100s w/o 2nd gear?
