125-200cc 12/48 gearing

anybody else out there running 12/48 on a 144 just bolted it on Friday raced it today got the class win against a field of mostly 250s its all stock but the gearing all i can say is that is one HARD HITTIN,PULLIN LITTLE BASTARD ill tell the truth its the nephews i rode it after the race just to see i'm 6 2 390 yes 390 ridin for 40 years & it pull me AS HARD AS I WANTED a gearing change really seems to be an answer

I am running 13-53 gearing on mine and I like it, my left foot is pretty busy at times but it will climb trees!

damn 4.076:1 ur shorter than we are but the nephews diggin it yours stock?

No,stock gearing was 13-50. I have a 36mm lectron carb and recently put on a fmf fatty pipe. I ride a lot of steep,tight stuff. I may go a tooth or two less on the rear if the rear sprocket ever wears out(stealth sprocket-lasts forever!) Works for me!

yea i went with an OE 12 & 48 supersprox & RK O-ring and had it all cryroed we'll see how that lasts

13/52 gearing is the way to go on the 150 & 14/52 is best for the 165. 12/48 is exactly the same as 13/52.

I have 13-52 on the WB 165 and its all smiles here.
would consider changing it with the next sprocket set change, but would probably go for a 13-50.
on the 125 cylinder I did run 12-50
I would not know how much the lectron would add and if I would need to adapt the gearing for it.
