[replyingto=lonesloper]lonesloper[/replyingto]I bought a set of Vee's and they are head and shoulders a better tire than factory at a good price too.

Your looking at buying an 86 or  main jet size and if it a carb where the idle set screw is sealed, you will need to unseal and possibly give it one turn out. That's a ball park because depending on conditions of engine load and temperature in your local, you have to fudge the mixture richer or leaner as the case may be. The thing to keep in mind is you will want to get a new plug and after a short ride, look at it for color. There are online sparkplug charts to guide you however I would describe the correct plug color as a dark tan. Hope this helps, Good Luck. |

[replyingto=lykos23]lykos23[/replyingto]Okay, how about a busted up GY6 139QMB rear rim then? I have an ideal of cutting the splines out and building a flange to mount a wheel.

There's a couple of ways to go, it simply is a matter of how much power you want to make in what RPM range. Yes you can go the big cam but you really don't have to. There are a lot of small upgrades that will add to the overall power like the NKG plug and a aftermarket coil or a aftermarket variator.

I'm a bit confused, moving the needle changes the off idle low to midrange fuel mixture, check.
Which way is richer?
Secondly, on cars/trucks we used to adjust this in part using a vacuum gage, is that still a valid method on the QMB139 small engine?

[replyingto=kavid2013]kavid2013[/replyingto]Is that a picture of your scoot because I have the same one...
You put on a kit and that's a good start but if you haven't yet, go get the NKG plug, a better air filter, exhaust and aftermarket coil. Yes you also need to rejet the carb. These will put you into the upper 40s.

Thanks terrilee. Getting down is not a problem, getting back up takes longer. Or... disconnect a few wires and bolts and just drop the whole engine out. |
