2021 Xpro Titan DLX

Worked on the carb today as i could see from the plug she was lean on idle and hard to start. A couple of discoveries:
- the stock PZ30 has a metal cap over the idle screw, you can twist it off with plier to reveal the idle screw (so stupid imo).
- there is no idle air/fuel mixture screw
- pilot is a 37 / main is a 102

Since I had my old stock PZ30 from the Brozz, i decided to use it instead. I used 2 shim washers under the needle, kept the 37 pilot (Brozz was a 34) and changed the main to a 110. Turned the a/f out 2.5 turns.
Started right up and a short ride reveals it to be much snappier and no deceleration popping!

There should be a cap over the idle/mixture screw right next to the bowl on the bottom of the carb. Some are plastic and some are brass. The brass plug usually comes right out just from trying to drill it.

Really excited to hear your experience in the carb tuning area. You mentioned there is no air/fuel mixture screw and then mentioned turning a/f out 2.5 turns. What are you turning 2.5 turns? Or just a keyboard mistake? Thanks

I had my old stock PZ30 from my other bike, Brozz Recon (which im currently running a PE30 carb on) and i just used this carb instead on the Titan as its the same exact carb but with the a/f screw exposed.. i adjusted the a/f on this carb and its on the bike now and running well.
