80 is more then enough from what you have done.

Change the retaining spring to atleast half of the current compression strenth in the speedometer. You will see a major change in speed readings.

agr ma kuch na bhe krta tb bhe 80 hoti yr any advice to achieve 9 to 95 top speed or even 100 !!

[Hassan1991]

Install stock sprockets (gerrari).
Rest this bike will not go above then 85-90 no matter what you do. Better be happy form what you got and drive safe. 70 doesn't stop after 60km/h so stay under that.

[abdullmateen1234]

issue is not that these bikes can't go above 90 ! my friends bike is stock 70 20 model and his bike is faster then me after every thing done on my bike ! so i just want to beat that guy by driving safely just need 10 to 20 more speed ! And one more question running ma bike kam bhagti ha kia ? ya free hoti running ma bhe utni bhagay ge jitna running ke bad ?

[Hassan1991]

Depend upon how the bore is set. If it's tight you probably already seize the engine.
Told you install stock sprockets. And get the runner pipe of hero. Pz22 is useless without old hero head and runner pipe.
Again don't go above 60!

[abdullmateen1234]

can u please tell me about runner pipe what is a runner pipe ! Plus my pz22 carbeurator band is small carb hole and and band hole is not matched !! this will cause some issues or not ?

[Hassan1991]

Pz22 have bigger venturi holes.
Runner is the pipe on which you bolt the carburetor. Which is in between the head and carburetor.
Or you can just install original carburetor.
