    I built my son a new ride with a Dax 65cc kit. My ride has a dax 70cc - the kits were similar, but had a few differences in hardware here and there. What is really different is how smooth this little 65 is compared to the 70. Much Quieter, smoother by far, even during the 1st 5 min. on that "spankin" new motor. So what gives? Are they really that different? I enjoy the 70, it runs well over all but gee wiz, this 65 right out of the shoot is going to be nice.

    Anyway, some of your feedback would be great.

    By the way, out of the box I put the new clutch "roller" mechanism I saw posted and it works really great, along with the derailer sprocket instead of the nylon roller bearing - some great ideas from you all, Thanks!

    My Son Bailey will be introduced to the forums too, along with his new ride and a photo. At present, he can't wait for me to get home from work so we can start breaking it in. (I did not tell him I was up at 6am this am to take a first ride - could not resist after finishing it last night at 10pm)

    Yes my son Bailey and I do most everything together, sometimes I am not sure who is more of a kid! He has an electric scooter and we have tried to go on a few rides together but range is a factor on the e-ride and as he says, "I feel like I am riding at Grandma speed" Now we can cruise together, something fun for us both for sure. He got the bike for xmas, and the motor for his birthday.

    Thanks for the feedback!

    Good story Topher, I had to laugh when you said you woke up early to go for a ride.
    I'm sure Large will be happy to learn that his trick has once again made its way onto another bike!
    Your son Bailey is one lucky guy to have a dad like you and having "fun" together is a great way of "keeping in touch"!

    You've got absolutely the right idea with your son....communications,combined with practical "hands-on" experience together.
    I can't help u with the Dax problem but if Bailey has the better engine u could always get up even earlier and swap them..........kidding. ;)

    Ya got to love a smooth install. Maybe you should have set your alarm for 5am. So you could have busted him riding it before you snuck out at 6. HeHe....

    I thought I started my post in the frame mount garage, but if this is where it should be then OK - sounded strange to be in the parts pile!

    Augidog, thanks for the links to the 65/70 - very helpful!

    The motor is running well, week on any low grade hill though, wondering if I should adjust the carb ring to run richer. After a few short rides - about 4 miles total the plug is dry and light choc. color. Maybe I need to richen up? I know the power should start to come up soon, would have thought I might have a bit more torque though. I don't want to be too lean.

    going up our street is a low grade hill, when on the throttle anything above 1/2 it bogs down, if I back off a bit I can hear the motor is "happy" but having to peddle quite a bit. Lean?

    I live at an altitude of 3500 feet.

    topher...i put it in here as a consumer-review of sorts...however, if this turns into a project with discussion & updates on the build, i'll gladly get it back into the garage :)

    let's start with current plug-gap, needle setting, and mixture specs...?

    if the plug is really dry, try the next setting down on the needle:

    I have run 2 65cc engines and can vouch for their smoothness but I think I'll be stickign to the 70cc engines in the future because the 65 is too weak for my tastes and unfortunately high altitude.
