I’m thinking about changing from the SE air cleaner assy PN: 29042-04B to the SE Heavy Breather PN: 29264-08. I have V & H Short Shots currently and 45-185 jetting for my existing setup. Do you think I will need to re-jet for the Heavy Breather or just some air/fuel adjustment? Thanks for your input!

 

While every bike differs a bit, you should be fine. If anything, the 185 may be a bit on the fat side.

A 45 or 46 pilot and a 180 main are typical.
