"Fuel" needs for the Two-Stroke

I was completely cought off guard about the leaded fuel.
Does this mean that you still use a 2s oil?
What are the downsides to using leaded fuel?
I am looking to get the most life out of my bike since I don't keep it at high rpms...I am hoping to have it last about a year between rebuilds.
I posted to the jetting section about the surging I am experiencing. It sounds like this could be a solution.

Yes on the oil allways.

What are the downsides to using leaded fuel?
Bad on the environment and cost.
I burn 111 octane leaded fuel @ 5 dollars a gal.only because it's cheaper than 101 octane.
If I'm short of cash I'll mix 50/50 with 93 octane unleaded pump gas.

Pull maintenance on your bike often.  Keep air filter clean , change trans oil allot.
Change radiator fluid and brake fluid at least once a year.
Do the cable lube and back brake pedal oiled just like the owners manual.

Thanks for the response.
Does the leaded gas cause a carbon buildup greater than what you would normally get?
Are there downsides to switching back and forth, such as if I want to try it, or if I simply want to use it when I can?
Do you recommend only using pump leaded, or would an additive be fine?

I am not sure I understand the octane vs lead. In other words, what is the difference between 93 Octane and 93 leaded? Doesn't the leaded burn slower, so I really wouldn't need to use a higher octane? If that is the case, does that mean that lead can be a substitute for octane?

Thanks

I'm by no means a fuel expert.  Unleaded is just that, no lead in the gas.  When I had my 65 Ford truck motor rebuilt they installed valves that could handle the gas they make today, unleaded.  If you burn leaded gas in a new car it will clog the catalytic converter.  I've run pump gas in my K5 and it seems to not run as good as running the leaded race gas.  I think you should go back and reread the first post in this thread it will give you a better understanding of octane.

I understand how octane raises the flash point so that the rod is at full extension when it fires, but is that the same thing that lead does?...or is lead acting as something different?
