    Cavitation FIXED

    Second ride today. Now at 5 hours. Best news is cleaning the assembly grease off the pump seal totally fixed the cavitation problem. Acceleration rocks!

    Speed was so-so as there was wind, chop and alot of traffic. I hit 65.7 with all fuel bars showing but later when fuel was low the conditions were not so good - did see 66.1.

    My speedo is really off. 30 mph steady on the speedo is 44 on GPS. 40 on speedo is 55 GPS. I rarely see 50 on top speed runs. The speedo will spike to mid-50's and even 60's every now and then.

    The speedo wheel looks like the same one Kawi has used for years. If I remember correctly, you can slot the mounting holes and and make it adjustable which can help calibrate it. Some one needs to make a Speed-o-healer like they have for motorcycles. That way you can calibrate it exactlly.

    Yeah, I tried three impellers from Skat.

    They all slowed down top speed performance.

    Let you know when I know.
