  1. Back in the day. With no gps. The worst thing about racing at Keystone. Was finding the dam place. Then the DUI check points after 12pm coming off the turnpike. Thank God for O'Dools.
    I think the success your seeing.. Is because the guy has 170CI on a stretched ProMod chassis Take some weight off the clutch. Lower the rear tire air pressure a half pound.

  2. Good racing but $100K ?
    They should have a $20K class where you can spend no more than $20K on your bike.
    Probably a street bike with a longer swingarm and better clutch.

  3. Back in 1980, I had (the late) Alan Sputhe build me a 78 CI Sporty..XR style…it cost me $4K a good hunk of change…but it was pretty fast, I never race it, but it's easy a 10 second bike..Same type of engine as the cover of August 1980 cycle world…and a bear to kick-start.
    It's still fast enough for me, I'm 75…it's even faster than my S&S 93" Knuckle-head sidewinder…that one, maybe 60 horsepower…maybe…
    So these big gas engines cost $100K…what about the Nitro motors..?
