Race Gas?

I was told by a Vintage husky mechanic that I should be running race gas like VP C12 in my 84 500 CR not to increase performance/power which it certainly does not need but to burn cleaner and not carbon up the piston/head. What some of your thoughts on this out there? What does everyone else run, race gas or pump gas? Todays pump gas does not last very long. Looking for some real stories from some real owners.

thanks

Have you tried polishing the dome inside the head? mirror finish it.

Don't reflects more heat to dome of piston causes piston dome to over heat and possibly hole it. Polish dome of piston if you must polish anything. Later George

4 gal. of 100 octane leaded airplane fuel and 1 gal of 91octane unleaded=98.2 octane in my 78 390 with a thin base gasket-- runs clean.....airplane fuel is about the same price as 91 last time i got it!

Gas being a little pricy these days, I mix a 50/50 mix of VP110 and premium pump gas. My thoughts are you only need enough octane to prevent pre-denotatation. Been doing this for 2 racing seasons now.
no foul plugs and bike runs crisp.
