36mm. vs, 38mm. carb

Recommended Posts

I've heard the 38 mm carb on a 2003 cr125 is better than the 36mm. What is the difference and is it worth getting? Some people sai the 2003 Cr125 already has a 38mm.?

Thats what I was thinking about getting because I thought the stock one was a 36mm. and I was gonna get a PWK 38. So how much better is the Pwk?

The PWK has a much better pilot circuit and will run cleaner at small throttle openings. In my opinion they're easier to jet also.

At full throttle there's no noticeable difference in performance, so on a 125 the expense of buying a new carb just to get a PWK is hard to justify.
