Hey everyone, want to say thanks first off to everyone who posted anything troubleshooting throttle bog downs, how to swap carbs, and anything else in that area. I successfully replaced the factory carb on my taotao roman 150cc scooter and put a straight pipe intake with a cone filter head.
When i got the new carb i figured i'd put a new air intake on it too, ordered them both of amazon (goofit gy6 24mm carb and a newmotoz 42mm cone filter) i thought i would have enough clearance to put the filter straight on the carb but there is a cross bar in the way. i ended up getting a 38mm or 42mm i can't remember (it was the smaller diameter one they had) 12" flex car exhaust pipe from auto zone and a 45 degree flex rubber pipe intended for plumping from lowes, totaling 50$. after getting it all installed i was only getting to about 3/4 throttle before the scooter would stutter, so i had to order a new jet kit (this is after i moved the float needle up to the last notch).
Installed the 120 jet and fired it up, i now can get up to 20-25mph with a flick of the throttle and accelerate through 55 no problem. acceleration slows down a lot near 60mph, but i did get up to 63mph on hilly road. No doubt it could get up to 70mph I just haven't got out on a straight shot road yet. The top speed for this particular moped was said to be 45mph so for 50 bucks i'd say a 20mph increase is great.
not sure if anyone will read this but if you do hope it helps, will gladly help if you have any questions
