The more you lean it back ,it puts more preload on inside tire when turning to help you turn. Not enough makes it ( push) and too much makes it want to pull straight in the turns and burn your arms off fighting it. That's just my experience and there's a lot more too it. I'm still learning how to perfect it and it's hard because every track is different.
I had good luck last year . This winter I tryed for weeks. I gave up, after a short text back then no reply for another week. . Told me that he has a family and he does it only for a hobby. That's fine with me but when you give me a time to call you,at-least answer your phone and talk ! It was totally rude
Nobody got a magic manual of Briggs jets? The only ones I can find say early and late date code. Or high altitude jets for early and late date code. ( that's only for the mains) None list jet size . They only list one part # for lows. I ruined some #54's looking for #50 to 58 low jets if there even available . Thanks for any help
