Anybody got the carb specs/differences for the RD125LC 10W and 12A carbs, got a 12A carb in that is going onto a 10W engine, currently the bike doesn't run too well or rev out, I suspect the internal specs are very different so looking to modify the 12A carb to match the 10W one
If not, does anyone know of an alternative carb for the 10W that will work well ?

Hello did you sort this as thinking of doing it myself but struggling to source the 0-8 needle jet. Sourced an original 12A 00 carb. Any help appreciated. Thank you

If it's any help, I've had 125LC's on and off for over 30yrs and no matter what anybody says, they will perform pretty much the same with any model of 125LC carb as long as the main jet and needle clip position is correct for your setup.
I've run 12A, 10W and 11A carbs on them and they will all give roughly the same performance.

Anyone tried running a 125 on a single PWK28?

Anyone tried running a 125 on a single PWK28? It's a good call. I've got some PWK28's on my Hyybrid but sold my last 125LC recently   |

The air jet in the 10W is much smaller too. The Ledar kit was either 1mm or 1.2mm ish
