Not necessarily you have a bigger carb which allows more fuel with a smaller jet. If you had put in a 30 or 32 carb you would have needed to drop the main jet quite a bit. You will not know until you put a load on it(ride it). Bring it up slowly and see how it takes the throttle.

I would say lean but all bikes are different it smokes some when first starting up, it idles perfect, stops smoking after about 30 seconds, runs great, I'm just riding slowly for the break in period only 40mph, I can really tell a difference in power and performance! |

Like I said right after you start it put your hand by the muffler and then smell and look at your hand. It could be fuel since the ENRICHER is feeding it extra fuel and or if you had to crank it over a few times unburned fuel will come out white looks like smoke.
If its bluish then that is oil that may have sipped past the valve stem, and only happens on starts and goes away until the next cold start.

...you have a bigger carb which allows more fuel with a smaller jet. Can you maybe explain the physics of this? It's not making any kind of logical sense to me. You are claiming that a smaller jet is able to pass more fuel? What majik be this?  If I'm not mistaken the numbers on any given jet are generally a reflection of the actual physical size of the opening. A 112 jet pulled from a smaller carburetor, and installed in a larger carburetor is still only physically able to flow as much fuel as will pass through the opening, but the larger carb is capable of flowing much more air resulting in a lean condition (all else being equal). Going even smaller would exacerbate the condition. What am I missing here?  |

I did the ncy 61mm kit it was harder to get the piston over the jug the compression rings are super stiff and the oil rings slipped out of the slot twice. I had to take the piston off twice and rearrange the oil rings hopefully you didn't fold one of the thin oil rings into the same place as the other, it did that to me twice. Only kit I've had this issue with and it would definitely cause it to smoke if this happened.

Yea my brother had a hard time with the rings like you did, he finally got them right, it smokes on start ups a little, sometimes it doesn't smoke at all...other than that it runs super great! And I even like the power, even though I haven't gone over 40mph, and not even hitting 1\2 throttle, and staying at 5000rpms, till I feel comfortable after break in period. |

yeah i did the ncy 61mm kit waiting for my cam to come in tomorrow and ill finish it off. The rings were super stiff i had to use 5w 30 oil to get it over the jug, its thinner. The oil rings kept folding in had to take the piston off twice and rearrange the oil rings. Cut my hands in the process super stiff rings which is good i'm sure it will be a good improvement seems quality.

Ok i got my kit all done, it runs much better with the ncy 61mm and a14 camshaft no smoking but i get pops on deceleration now, i even upjetted to a 120 and still pops but runs strong and fast haven't speed tested gonna break it in a bit.

Jet it rich too much heat in that thin cylinder will cause it to crack im up to a 122 jet now popping stopped runs like a champ. I'm running a 122 main 40 pilot gained 9 mph on top and more torque over the 60mm kit. I may do a 30mm carb in the spring 67 GPS I'm happy not broke in yet.
