I was hesitant at first to remove my airbox. But I'm very happy now that I did it. My scoot looks so much better with a unifilter.  taotao powermax? How long have you had it? The little metal decoration with the holes in it that u can see in that pic rusted on mine pretty quick |

Switched from 38 to 40 idle jet, haven't taken it for too long of a ride, but it seems the popping hasn't changed much if any

What do you mean everything on the fuel line? Also what about the second line coming off the intake manifold? And all the canisters

Sounds like you've got a good plan.
I'm assuming in those 2 years you've never adjusted the valves or cleaned the carb?
Prob want to do both either way, but I'm thinking there's a good chance it's the valves since it seems like your problems arise once the scoot is nice and hot. Esp of its stalling the valves expand and are probably close to, if not, closed.
And either way cleaning and adjusting the carb should improve your performance

It was above where the belt is (the airbox) I think that's where the hose was running honestly i don't remember at this point, where would the hose from the cover (sorry don't know the name, the thing that covers where the valves are) go The one hose from the manifold goes to a splitter and goes to the petcock and the other split goes to the carb The second hose goes to those canister emissions things Ill take a better picture when I get off work you need to hang the valve cover vent hose up high and put some kind of filter on it, so nothing can get into the valve cover. I would also eliminate all the emissions crap and close off the extra vaccum lines. Alright I've got an extra fuel filter ill throw on there, right now i have the hose hanging down so that's probably not helping thanks for the responses everyone ill upjet tomorrow and report back I've been meaning to get rid of the emissions just been lazy, is it as simple as just capping off the second port from the intake manifold? Would it be a bad idea to switch both the idle and main jets at the same time? Or should I do one, see how it affects it, then do the other if no improvement just a pain pulling that carb out over and over in the hot florida sun I've got no covered area to work under |

I believe it was a 108, I actually bought a new carb just bc I didn't feel like trying to remove all the tamper proof stuff
It was listed as a 108 but the jet wasnt labled when I removed it, I only have increments of 5 so should I try out a 120? Or should I do a 40 in the idle jet?
Only reason I'm not sure is bc the popping only occurs if i run around 1/4 - 1/2 throttle than let off
If I run WOT no popping occurs at all (this was not true when I had a 35 idle in, I would get popping on any deceleration)

I think you need to go up on your main 3 or 5. Running lean, IMO. You added a good amount of extra air, with the UNI, and the exhaust. When you are lean, things run hotter. What size was your original main jet? These things are almost always running lean from the factory. Where was this hose that went back to the factory airbox attached to on the other side? Are either of your hoses from the manifold open on the other end? No neither of the houses are open on the other end, i have yet to remove the pair system one of them goes to a splitter that goes to the carb and petcock, the other goes to all those stupid canisters the hose to the airbox is the one that comes off the top of the head, its just barely visible in the bottom left corner of that picture |

Also not sure if it's related but my vacuum lines have become a yellow brown as well, they were teal  not sure if this could be related |

Hmm ok so could this be from me removing the stock airbox and just having the hose that went back to the airbox just hanging? Honestly i can't figure out how to completely eliminate this problem I feel like I have to be missing something obvious
My header has turned a dark bluish from the original stainless and I'm worried about this happening to the muffler as well

Well upping it to a 38 from a 35 significantly reduced the popping, but not all of it, i thought the pop was from a lean condition?
I have noticed my header and even the muffler getting very very hot and it's got me worried
i adjusted the valves to .005 not too long ago as well

Well it turns out the breather hose or whatever it's called was pinched closed, no smoke coming out now
Popping isn't that often anymore but letting off at 1/4 throttle is still giving me a bang

So the saga continues
ever since I got a uni and aftermarket exhaust I've had nothing but issues
Recap: 150cc Chinese, 115 main and stock idle jet, uni filter aftermarket exhaust
Alot of loud popping on decel, made the scoot stutter when I would add more throttle
So I got some advice that I should up the idle jet to a 38
Fully disassembled carb cleaned and swapped the idle to a 38
I let it warm up adjust the af and took it for a ride and at low speeds I'm getting a noticeable amount of white smoke from the exhaust, even after turning it off more smoke came out with a burning smell
What am I doing wrong and why won't it may run right? !

Mine can go as low as 1k and be just on the verge of cutting off but it seems like my best performance is idle just under or on 2k
