I was reading up on oil at 540 Rat's oil blog (
https://540ratblog.wordpress.com/201...-test-ranking/) and realized the 10W40 Valvoline 4 stroke motorcycle oil I was using is rated at a very mediocre 65,553 PSI of shear resistance. So I drained it out(saved in milk jug for the lawnmower..) and put some 5W30 Mobil one advanced full synthetic oil in. This oil is rated for 117,799 PSI of shear resistance. MUCH BETTER! It also has the "evil" resource conserving tag on the bottom of the API label.
Guess what? No clutch slippage! Full throttle and high RPM, or full throttle in top gear, still no clutch slippage.
My 42T sprocket showed up, but I need another master link to install it, still waiting on that.
