Stupid Question, what kind of gas goes in a '70 CL350? I got my Honda manual and it doesn't say anything about the k2, and the k4 says it requires 95 octane?! Should I be using regular, the next one thats better, or the best (most expensive)?

The type of gas that was used when these bikes were new contained lead, but lead was phased out around 1980. Since it called for 95 Octane you are going to want to run the premium or the Super as they call it now. The Octane rateing on the gas will be listed on the pump. To be safe just go for the most expensive gas they have at the gas station, that isn't diesal.

And , if you feel you want or need to , you can buy lead additive at any auto parts store .

I'm not sure , but don't the valve guides use the lead as a lubricant ?

I mix a quart of 111 leaded race gas into my Scrambler's tank of premium 91 pump gas in the summer time.

Guys,
The octane rating of 95 back then was regular grade fuel and was rated by the Research Method. Today, motor fuels are rated by an average of the Research Octane Number and the Motor Octane Number - (R+M)/2. For today's regular, that comes out something like (95+79)/2 = 87. These bikes run just fine on unleaded regular, provided they're tuned properly. On the subject of additives, you can buy a lead "substitute", but not an actual lead additive. There'd be major jail time involved for anyone caught selling something like that for use on the street.

Ray,
Many guys see the word race in race gas and think it'll make a street bike more powerful. That's not the case. Neither race gas nor 91 "premium" will add any power if the bike isn't pinging on regular. In fact, it could reduce power. Best power occurs when the engine is just shy of pinging.

There are as many opinions about this as there are members.
Best way is to try it yourself.
A few tanks of 87, then a few tanks of 93 or better (if you can find it).
If you think it's better one way or the other, go with it.
I wouldn't worry much about lead, just my personal experience.

Chevron Supreme with Techron. 93 Octane. Cleans the entire fuel system up and keeps it clean. Only juice my CL 90 or my cars get.
