I'm in the process of putting together the motor on my cafe' project.
I'm hunting for jet sizes and needle sizing for the 550.
I plan on running pods and have a 4 into 1 header ready to mount.
I'm sure many others have run this setup and would like to get suggestions on what would work best for normal use. Not trying to create a high performance bike. Just one that will run well for around town rides.
Thanks in advance for your help!!
Stock pilots are 32.
Stock mains are 92.
Stock needle is a fixed clip position.
I recommend using the stock needle unless you know for a fact that the adustable needles you find are either 100% TK (factory original adjustable available outside the U.S.) or are non-counterfeit Dynojet needles. I have run into counterfeit Dynojet needles and bad replica factory adjustable needles.
Here's a link to the various needles and what to avoid:
These are just very preliminary starting points. The best way is to make sure the bike runs correctly stock first. Then start making changes. This is not always possible, so a starting point is needed. If the bike doesn't run well at all, then you will really need to check a bunch of other things first.

Jetting is usually the last step before final tuning.
