125 sx questions...

Recommended Posts

Hey everyone new member too the forum have been reading it for some time tho. Got a few questions about my bike, I have a 2001 125 sx I was wondering if there are any mods that can be done to the engine too make more power? Its got everything bolt on wise reeds silencer pipe etc etc... I am currently doing a full rebuild top and bottom due too infortunate circumstances haha. Are there any higher compression pistons better pistons in any way? Head or cylinder mods anything?

Yea it is pretty fast but I have been riding it for 2 years plus... And I'm about 220lbs so I could use a little more power if its available too me... So anyone have any ideas?

I put the 134 kit in my 125 helped a lot. Other than that get it jetted perfectly and make sure you keep the air filter really clean. I didn't realize how much power a 125 looses with a slightly dirty air filter. I change it out in between motos now.
