Keihin seem to always be popular....

Our OKOs are running good once we did the tech mod recomended by DRR.

Did the updates to the OKO 21 and its better but I am still not 100% or even 90% happy with it, even with tuning it in "Perfectly" with a dyno and air fuel meter it is still not up to what I would call "Good throttle response" although this is just my opinion and other will have different opinions, My boy is getting holeshots consistently and winning motos I would like to try a Keihin carb if possible, which keihin carb is it that i need for this 50cc DRR that will be a stock replacement and not stand out like a sore thumb??


Thanks, Corey

Just searched up the PE20 and it is nothing anyone could cheat with that is for sure, looks way different than the OKO21 which is a good thing, should keep'em honest around here.
