Need some help with jetting

[dudemc]

I just got a HMF slip on pipe, pro design Pro Flow K&N air filter fit, dyna FS CDI box. The Pipe came with a 152 jet. Any suggestions on Jet sizes and adjustments on the carb this is the first time I've messed with carbs. Any help would be appreciated.

you will have to get some more main jets and test it from like a 160 and go backwards till you find the sweet spot. it will stumble on the top if its rich. you shouldnt have to mess with anything else if it runs good now but the air filter kit will make it need bigger jet than just a pipe alone, and a cdi makes a hotter spark. you might need to go a couple bigger than suggested even, one of mine runs a 185 main:eek2:
