help with fuel/air mixture

[quikvrsixx]

i took the mufflers off and welded on a foot long extension with a slight bend to it only and also put on 4 individual cone filters on an otherwise stock 81 750L. i can olny get half throttle before the bike dies due to what i can only imagine is too much airflow into the carbs and less back pressure from the new exhaust. my friend has the same set up and same problem and had to restrict the filters by putting socks over them to make the bike run better. do you know if there is any other way to fix this issue or should i just restrict airflow to the cones since i will not be installing the oem air filter again.

Yes you need to rejet the carbs

Hi,

You've opened up Pandora's box full of plug chops and jetting changes. There is information and links on my website to help you get started. Look on the Carb Specs page. You can also search the forums for others' experiences.


Thank you for your indulgence,
