i have a 2009 kymco super 9 air cooled with a 70cc big bore kit.
I have a 19mm carb with an open k&n filter on it.
My turbokit.net racing exhaust was just too loud so i purchased their silencer. Now with only lowering the jet size from 110 to 92 to try to figure out the problem the performance is dramatically worse then with my original pipe. I also tried 100 and 110 in the new pipe too with nothing better.
I used to have a 110 main jet with great acceleration and hitting 8500 to 10k rpm's at WOT over 30mph. Avg top speed around 55.
Now i barley get to 25mph.
what do i need to do?
And will it be possible with correct jetting, that i can get the same performance as before?
