i'M NEW TO THE 2 STROKES, I just bought a 91 cr 125 to paly with. I'll be mostly trail riding and palying around. The bike bogs and stalls when the rpms get low, but screams mid-top.....Iit has a pro-circuit pipe, not sure about the sprocket. I would like to be able to pull the front wheel in first without it being wide open...Now it doesnt feel like it wants to pull unless I rev the heck out of it.....Any advise or help is appreciated....

What you describe is a typical 125. You can get the cylinder ported by eric gorr for bottom end, a torque pipe, and different reeds and achieve the desiired results or just get a big bore.:) ;)

Get rid of the pro-circuit and get an fmf fatty. I have one on my yz and it is a hill climbing trail monster with torque to spare.

FMF

I have seen the FMF ads for the gnarly and such. Which would offer the most torque? And how effective

FATTY OR SST would produce most low end, i would also suggest

to try CARBON TECH low end reeds cheapest area to start at to find some

low end compared to pipes and porting, made a big difference with my

01 CR125, make sure your jetting is correct.
