2023 YZ125 - Jetting Fix

After watching the 2022 chart on the vhm i see that the 2022 has more hp at 8000 rpm.

I know You can't just compare two charts but i don't see anything night and day different between the 2022 and the 2026.

Is the cdi a direct swap?

Yep plug and play.

Looking at that dyno and what takes parts wise to get there. An upgrade alternative in seeking more power for myself(215lbs.) and a few ppl that I know is to run the STIC PWK Super X 38/40mm carb. Though I wouldn't recommend it if you want to keep the 125 characteristics of no bottom, hitting precise shift points, working the clutch and waiting to get "on the pipe". I get it, some find that rewarding. Just sayin', there's an easier way to run with the bigger bikes.

The circuit design creates a strong fuel uptake at a low vacuum signal and it also creates a cool vapor state. The uptake principal design is about lowering float bowl fuel surface pressure while inserting Venturi velocity into the needle jet tube via perforations. This low pressure to high pressure differential creates a much greater efficiency in delivery. As fuel level drops, more of the perforations are exposed. More power is created as the mixture becomes leaner. Much larger pilot and main jets are utilized for this fueling capacity.
