    In short; I don't know but I know it does!
    Well the float was almost double the spec.

    I set them to 7.5mm. Testing tomorrow at the MX track.

    I typed that wrong.........should have said the the floats were half the spec. They were set super high, in fact the floats were hitting the carb about the same time the needle valve was closing.

    175 main, 45 pilot, 40 power jet, N3CW-3, air screw 1-1/4 turns out. 40:1 with Klotz R50 and 93 octane.
    Floats set to 7.5mm
    3000', temps in the 70's.
    Rode at the moto track with my boys this past weekend. Bike flat out rips top to bottom. Plug is perfect.

    Done with jetting. Hope to do a long loop this weekend to see if mileage improved.

    Need to pick up a Spark Arrestor to be legal.

    Shrouds are looking pretty hammered......I need to find some cheap shroud graphics.

    My oldest boy wanted to bet me who could ride the most throughout the day at the MX track. $10, for who could ride the most miles. We both use Garmin cycling computers to track stuff, so it was pretty easy to keep track of. I ended the day at 44 miles, beating him by only 1.5 miles. What a day.

    Nice trailer. Looks like the side door is wider than normal which is a very good thing.

    Got the bug for a bit of a project, so I am building one of these.



    Might now look quite as cool with my IMS tank, but we will give it a shot. Rim arrives yesterday, will be matched with Buchanan Spokes on stock hubs.



    Buddy of mine designed the graphics and they turned out great.
