Is the R/R charging, should be putting out 13+ volts at around 4K rpms. How about the lights are they working good.

If there is to much free play YES it will effect how much the BUTTERFLY is opened.
Normally 1/8-1/4 of an inch is all the play you should have before it actually pulls on the cable to open the butterfly.
But to test it, grab the Throttle wheel at the carb and turn it clockwise all the way HOLD IT THERE and now with the other hand grab the throttle handle and twist it all the way. NOW pay attention to the throttle wheel and let go. IF IT MOVES when you let go then you have to much play and may be loosing top end speed.

If all that is good then the next thing is to adjust the carbs fuel mixture, if the temps changed from mild to much coler then the motor needs more fuel. Follow this procedure to adjust the mixture it is a step by step so you can't go wrong. Alleyoop scooterdoc.proboards.com/thread/1499/4ts-carb-tuning |

First thing is to check all your hoses and see if something has come off their connections and or the air filter tube partly came off the carb etc.. If you could take some pictures of the carb area hoses it may help maybe spot something not connected. Have you checked the fuel filter, and make sure it is not partly clogged, you can usually tell if it is dirty or clogged when you can see black specks on the filter.

Great!! now bogging is the sound it sort of makes when you open the throttle which MEANS to much AIR and not enough fuel.
Have you done anything else to the scoot like putting on a free flow filter or changeing anything on it?

Yes adjust the valves when cold. Also a little tip, before you put the valve cover back on and button it up ROTATE the motor over by hand several more times and RE-CHECK you gaps a .005 feeler SHOULD not slid in and the .004 should. Many adjust them but when tigthen the lock nut the stud moves a little and your gap is off.

Yea most folks do not even think about the valves being tight and they go right for the carb and start to adjust it to compensate for the tight valves. But then it valves get worse and no adjustment of the carb can help at that point. So then they adjust the valves and THEN what happens is they forget to re-adjust the carb now the valves are adjusted. So adjust the valves then test out the carbs fuel ratio mixture and adjust as needed.

Can you describe what it does when you are on it and you open twist the throttle to go? Sounds like it has a problem with the fuel delivery.

1.6v the battery is really dead, I think a new one is in order. Once they drop that much it usually means it has a couple dead cells.

Have you checked if it is charging the battery start it up and check the battery and rev it up and see if it is charging the battery? Also how are you lights are the really dim or nice and bright ..
If all that is good then I would suspect your multi meter is giving bad info.

The liquid in the air box is probably due to hard starts, cranking and cranking it get it started. But check if it is OIL or GAS, if oil then I would suspect the VALVE COVER VENT connected to the air box and is squirting oil through the hose into the airbox.
The FIRST THING you want to do before adjusting anything is ADJUST BOTH VALVES .004 inchs. After that if still some issues then that is when you need to adjust the CARBS fuel ratio mixture.
Also take the AIR FILTER OUT and wash it wish dish soap and let it dry and clean out the air box.
If you can get some pictures from the top looking down to see how everything is connected also the hoses going to the AIRBOX.
Oh almost forgot the leaking hoses, what you want to do is pull them off CUT abaout 1/2 off the hose to get to good solid part of the hose. They do stretch and wear on the part that fits over the connectors.

Bummer that is to bad you should have marked the OEM before taking it off and run it at WOT and see how much of a mark was left. Then Mark it again opposite the first Mark put on the bigger fan and run it at WOT and see how much of a mark was left. Then you could of actually seen if the bigger fan did anything or not. Yep, that is why when you make your own you have to make it like this: Alleyoop  |

You did not have to buy parts it just needs a little adjustment on the carb. If the Fuel Ratio Mixture is way off the motors are very hard to start. Did you also put on a FREE FLOW FILTER or just the MUFFLER? Since you put on a performance muffler it is now running a little LEAN on fuel so Turn the FUEL RATIO MIXTURE screw COUNTER CLOCKWISE at least 1 full turn. Then once you get it started let it idle and warm up for at least 5 minutes so the ENRICHER cuts off the extra fuel, THEN ADJUST the CARBS MIXTURE. Follow this procedure: Alleyoop scooterdoc.proboards.com/thread/1499/4ts-carb-tuning |

The 35 watt bulbs draw more juice so maybe a lower draw bulb will work better. Some scoots do come with 25watt bulbs and to some folks that ride at night a lot get 35watt bulbs for a little brighter. But then they usually have trouble with the charging system due to the stronger bulbs drawing to much juice.
Hard to tell if the first post is high beam or low bean but you could verify in a flash by switching and seeing which is which.
