Still working on empting the gas tank. All the above mentioned things are good to do. Being that I take resonably good care of my ride, the maintanance things will not be the trouble.

The big change was on the engine rebuild, shaved head and new low profile cam. I still need to check o2 sensor and maybe mechanical advance, and vacuum routing to distributer, it's always had a flat spot for the past, well, since I've owned it, but it always passes smog, but lately only after a second try.

I get sent to a smog only on renewal and I called the number at the bottom of the test. Because I have been sent to a smog only and failed, I can apply for finacial assistance and get it. The state will pick up $400 of the smog repair, after I spend $100. (has to be smog certified shop). But while on the phone the tech guy, told me to run methanol and I should be OK as the methanol doesn't "pop", it "burns", keeping combustion chamber temps down. He also said that retarding the spark will help also, but you have to stay within manufacturers spec. So cheap and easy, (my middle name) Denatured alcohol it is.

Awhile back I read the thread on shaving heads and cam timing varience.

I think this is what is happening with my motor. $150 psi compression should not be trouble, but the timing could be.

Kevin, when I'm done I can post the results in your previous thread.
