you will need to check the clearances, you maybe lucky and get away with it, but then again theres bound to be some that are out i would have thought!

 

[nismo-400R]

what are the clearances ment to be on the pulsar?

 

[Mondorno]

The clearance between the cam and the rocker arm should be 0.14-0.17mm when cold.

 

[nismo-400R]

so anythin between 014-0.17 is fine?

 

[Mondorno]

Yep :thumb:

 

[nismo-400R]

do i have to check the valve clearance aswell?

 

[Mondorno]

No, just check that the clearance between the cam sprockets and the rocker arms is 0.14-0.17mm (when valve is fully closed)
