im not "buying all kinds of bling" dont call me a yuppy, its got good speed but it feels like it should accelerate harder, you can hate all the yuppies you want but if your not gonna answer my question then you can just shut your mouth... if your such a genius send me a message and tell me exactly how im supposed to ride it for more low end power

When all else fails, change the gearing on the rear sprocket, go to a different ratio for a faster ride. Do some experimenting, or ask your mechanic how to get a faster gear.

Do you really need it go any faster? The next step might be you.

Try a couple of MX advanced riding schools.

I thought I was doing good untill I attended Ron Haslam's Honda Race school, here in the UK. After one day I was 1.5 seconds quicker then before I started.

That a big difference.

rear sprocket, bring it up out two to five teeth, larger chain to accompany the larger sprocket... could always change front hearings too but they are pains, big bore kit def. help, bbr rev limiter, way better than stock, new exhaust adds hp... hope this helps some

looks like you got a deep pocket to dig into.. I seriously doubt you can ride to the full potential of that bike youhave.. stop buying all that stuff and acually learn how to ride it.I hate when all you yuppies get into a mans sport and ruin it with all your bling and suv's.

You gotta keep the revs up on a 125 yz. I had one, and at low revs it was a dog. Let her sing, and you will be amazed.....
