Don't know where you came up with it breaking down in a couple of hours. Wet clutches are made to slip, slipping casues friction thus causing heat. The steals between the frictions in your clutch are what heat up. ATF is designed to run at an operating temperature of 175 degrees, 20 degrees more will cut the service life in half. In car the fluid is circulated and cooled, not to mention there is much more fluid in the system. In a banshee there isn't that much fluid, and it never gets cooled. So when your hot lapping your drag bike launching at 8k, when you stop and take off again, etc your clutch is slipping and heating up the steals and oil. The last stock clutch setups I have torn apart recently had discolored steals, both on alky drag bikes, one with lockup, the other without. The one without the lockup was slipping when I pulled it, steals had bad discoloration.
