    I could probably plug the air intake as well... but now I'm imagining rubber corks getting sucked into the engine...

    Maybe I'm just a fat, ham-fisted, suburbanite, and I should be happy with 60mpg? I just thought flogging it I should get 70, and milking it i'd get 90mpg.

    I'm going to spend more time inspecting my drive train (belt) and looking over the ignition end of things.

    Next time I have the carb off, I'll see if I can do the bystarter check as prescribed by the manual, but I'm not really sure how I'm going to draw a vacuum on that little hole that's 0.2mm in diameter on the engine side of the carb.

    There's a fascinating website at www.craigvetter.com where he has a long story of trying to improve on a Honda Helix to get better mileage at speed. A failure ultimately, but a lot of info and fun.

    Scooting around the neighborhood, parking where you want, and generally smiling your way to work is what it's all about. Don't overthink the whole deal.

    Yes. You're right. Even at 50mpg it's fun. But I got that on my KLR650.

    I took a 62 mile backroad joyride at 35-45mph today as a test. Filled up before and after and got 65mpg.

    The beauty is that I love the challenge of improvement. This whole thing is fun for me. I'm not going to sell the thing if I don't hit the mark, bu if I do have an "Ah-ha!" moment, it will be glorious.

    Thanks for playing along.

    Last tank 58mpg.

    I do have a new problem: roughly 40% power loss on hills. Off/On like a switch. I'll probably just start replacing ignition parts since they're so cheap. Checking grounds, connections, etc.

    Also ordering new jets just so I can be sure they're stock. The ones I have don't have any markings, although they look like they're original.

    My WRr gets 52 to 56 mpg combined (interstate at 70 mph plus some city) the CRF is reported to do even better, both burn cleaner too:D

    That is my MPG... just trolling for fun. hope you get it all worked out....
    In Wisconsin, the family fleet MPG AVG combined figures for each

    Hyundai Veracruz (family truckster) = 20
    VW Jetta TDI = 45
    Yamaha WR250r = 53

    overall (simplified/CAFE) avg = 39.3mpg

    The VW is BY FAR THE MOST impressive, due to GVW, passengers etc... Damn thing will do 52 mpg on a HWY trip at 75mph. that is truly awesome.

    I am not a hyper-mpg guy by the way.
