I don’t ride much

Is 4stroke true fuel ⛽️ better for my ct70. I’m no mechanic just don’t want to do any damage. Thx Anthony 70 cc junkie.

If you're talking about the best fuel to leave in the bike, while sitting, unused, for long periods of time, VP Hydrocarbons storage fuel blend gets my vote, followed by Trufuel, avgas and...coming in next-to-last...non-ethanol pump gas. Trufuel is sold at places like Lowes, Menard's, Home Depot...it's pricey. No gasoline is going to last forever and anything left in the carburetor is going to evaporate, leaving behind varnish. Best storage practice is to drain the entire fuel system dry...tank, lines & float bowl. If your bike has a steel fuel tank, a shot of fogging oil will prevent rust.

If you have a choice, drain & dry the fuel system...that'll prep it for an indefinite hibernation better than any other method. This is an easy fuel system to drain.

You'll also want to drain the oil and either refill the crankcase with clean oil, or leave yourself a note "add oil" on the bike; then rotate the crank until you feel compression...both valves closed, combustion chamber sealed.

The missing piece of this puzzle...how long are you talking about leaving the bike parked?
 
Not long maybe 1month at a time being in the New England winter seems long but I do try to start it when I can after going to the local bar that urge comes on to start and wax it.

New England winters aren't that different from what we get here, in the upper Midwest. Waxing the bike is always a good idea. Keeping fuel in the system, without running long enough/hard enough to run it completely through (replaced with fresh) and bring the engine fully up-to-temp is a bad idea...always was. Gasoline has a finite lifespan, a short one if not stored in a sealed container. (Hint: the carb is open to the atmosphere, at all times.)

Life is short and it's your bike to do with as you wish.
