HELP: what am I missing? By budthatsmyrealname (Read 346 times)

just about everything is upgraded and it pulls and tops out just like stock. just chugs up hill, tops out maybe 35 sometimes 40 on flats with the speed app.

50mm big bore kit (valves and cam)
exhaust
ncy cdi
ncy coil
intake
whopping 26mm hoca carb
hoca big manifold
variator 5gram weights
oil cooler (if that helps)

i think thats about it. i spent approx $1000 in parts. im so disappointed in the results. the only think really left i can do is a stroker crank and transmission kit, but im not going to spend that kind of money if its gonna give me little results. the jets are just right (at 100 main and 35 idle) , and the air fuel ratio is good. its tuned just right, it drives and idles with no probs

even my gf says she doesnt notice a difference. what am i missing? what more do i need? im not looking to race, i just want some fun horsepower and a daily driver

Trans and final drive,,,what scooter do you have?,

Sounds like some thing is not matched up. Trans and drive almost always helps get more power to the back tire.

Post a few pictures , front and both sides, a distributors model name means very little to identify a scooter from china.

That is exactly why I would be getting the right scooter for the job. A 250 is so much better suited for what a 150 lacks. Faster, 2 up, and hills. A highly tuned 150 can beat a 250 across an intersection though. That's a weight thing though.

Have you read the spark plug since all of this? With all the changes I would not be surprised that jetting to be way off.
A bigger carb usually just makes it harder to tune. The stock carb with a little bigger jets is usually all it takes there. Air going in has to be matched to air going out.
