Valve Cover Port???

[RyanosAlien]

Hey,

I'm starting to reassemble everything and can not remember were the valve cover port lead to and I can't find any pics or info on where that port went

Pictures please. It sounds like you misplaced the pipe from the exhaust port to the valve cover that then goes to the PAIR system.

I bought the scooter from a guy in peices so all vacuum lines and parts were disassembled but I managed to get it half way going good over the pass week, I ran the valve cover vacuum up to the intake and set the valves to .005 for both intake and exhaust, the air filter and box was junk so I threw on a off brand filter and oiled it and the main problem I'm having is since I wasn't the first owner I don't know what all the added to it, like I noticed on the needle in the float bowl there is 2 little spacers and undle full throttle it still likes to sputter and bog down granted adjusting the valves helped a lot but still feels like theres some thing I'm missing, I'm now looking into how elevation works with the carb I'm at 850 feet elevation and trying figure out do I need to go ahead and reject or what???? Lol it's a pain in the ass

P.S: This is my first scooter and it's a 2006 chau longbo LB150-19 150cc alien edition/name and I'm having trouble finding info on it especially what was standard equipment.

I'm new here, but I have been doing a lot or research.
If you replaced the stock air box with a performance filter, you may be running to lean now at full throttle. A lot of people are running a #115 main jet with the cone type filter. You might try the old box and filter as a test and see if it smooths out.

I order some jets off eBay the other day so I'm hoping to smooth that out
