How many HP can i win with a polini exauhst on a PK HP with 85cc POLINI motors ?
Hi Paul !
You can use the standard 16 SHB carb with a higher mainjet or a 19 SHB.
The 19 carb. is the better chioice to be shure that the engine runs reliable.
The 16 carb. needs 66-68 mainjet, and the 19 carb. needs a 80-82 mainjet.
Cheers
thancks man
and for the spark plug which are the better for my engine ?
Hi Paul !
I´m sorry, i can´t tell you the exact horse power increasement because we don´t have diagrams for any cylinder/exhaust combination avalible.
In any case this exhaust works very well in combination with your cylinder.
The torque and the top speed will increase.
Cheers
and for the carburetors have you an idea which work with my engine ?
