Restrictor header TTR 250

Recommended Posts

Hi, i read almost all the post for ttr 250, and nobody said anything about the emissions from exhaust. Has the ttr 250 from california version the restrictor in the header pipe?

I'm asking you this because here when it comes to exhaust emissions, they are really strict in that depatment?

- If i remove the restrictor, is it neccesary to rejet the carb?

When you remove the restrictor, the torque in low rpms is better or not? i think if we remove the restrictor, the low range decrease but middle and high range seem better, what do you think?
