    If you can find it in your area use 91 octain or higher non-ethanol gas.

    I am with El...sounds like air is somehow getting in there. I am sure you already checked this, but are you sure the slide isn't hanging or throttle cable getting bound?

    And did it rev before you did this?

    Maybe its too lean now when it get hot.

    Even if this isnt it, i wouldnt lean out a bike because it "feels doggy", lean out a bike when the plug looks rich.

    +3 on air leaks.

    Mixing octanes works, I mean, its real, people do it.

    That's good, you don't want it plugged.

    People do alot of things. All it does is create different detonation points in your cylinder causing different temperatures in different areas putting unnecessary wear and tear on an engine cylinder for no specific gain. People do it under the assumption it creates a different octane level which it simply does not. Fuel is fuel sure it will burn no matter what u put in it....mix fuel in water and it still ignites.

    I will try out some of your suggestions this weekend and see what I can come up with. I appreciate the help. I do not know if it reved like this with the 380 main as I never rode it top end much as it was so crappy running in the lower end I just parked it until I had time to rejet. Doggy isn't necessarily the word to describe why I rejetted.... The engine was acting like it was flooded out. My plug was showing fuel heavy. As I stated I haven't had this one long enough to get to know it real well yet just trying to debug .....race is cancelled so no riding this weekend

    As in, I third the recommendation to not rule out the possibility of air leaks. Its a common way to say, "what they said" on a forum.

    As for mixing octanes, which fuels mix well, hot spots and such, as you may know, theres even more to it than you are describing, yet, it gets done with good results in the real world every day, despite the scientific explanation.

    That's a whole Lot of commas. ..... I get what your saying on the air leaks that has been my assumption from the beginning but passed leak down test twice so I'm looking for other ideas.

    Leak down test doesnt acount for air leaks between the carb and intake.

    My opinion is that its lean, but im no scientist, and also, I have an abundance of commas, unlike many others, and im just trying to spread the wealth, you're , and by the way, how much you selling it for?
