3 of 5 Multiple early failures October 3, 2019

These were my go-to seal for minarelli and tomos, and whatever else. I've used them on stock and mild bikes of my own, and for repairs of other peoples bikes.

But lately on my personal ripper tomos, these have been failing inside of 400 miles on the magneto side. Starts with a slow oily seepage, and eventually leads to loss of power and lean condition. I always take care to install them gently with plenty of lube on the inner lips. And the bearing is in excellent shape with no slop. Ive had to switch to Viton seals, at least for this bike. We'll see how it goes.

Morini and Minarelli both use these crank seals.
Rebuild, rip, repeat
