CL450 Racer - Prepping For Loring 2015 Part 3

T-minus 12 days to leaving for Loring, and I am posting a quick update of the prep progress.

I installed the PAMCO, but ran into some problems setting it up. After a few weeks of little success and even less sleep, I ditched the electronic ignition and went back to the original condensers and points.

I also replaced the Dunlop K70 semi-knobbies with a pair of race-legal Dunlop K81 Roadmaster TT100's. These tires have an unbroken center ridge in the tread. When over-inflated to about 60psi, the tire contact area is extremely small, greatly reducing rolling resistance.

Finally, I discovered that the cam chain tensioner was stuck and had not properly auto-adjusted during the last two or three engine tune-ups. As a result, the cams were slightly out of time, and the chain had ground quite a bit of fine aluminum dust into the crankcase oil. After 6 oil changes, and running the engine each time to flush out the dust, the oil is now (moderately) clean once again, and the engine is making no strange noises.
