NC21 - NC24 Valve Clearance Guide

[EvanTate]

HI guys,

This is not my guide, I simply reformatted it for easier viewing and better understanding. For those of us that don't always manage to find the info on page 14 of a thread haha

Original by Mob Rules, Page 14 of viper_biker's NC30 guide.

I would suggest reading the NC30 guide in full before starting, and simply referring to this once you have a good understanding of what needs to be done.

I ACCEPT NO CREDIT NOR RESPONSIBILITY FOR ANY OF THIS

Admin to delete if this is unnecessary of course

Valve Clearances
 
Remove fuel tank, airbox, radiator and carbs (if space is required). Also loosen the Reg/Rec holder and front coils and move them out of the way. Make a note of any wires you disconnect for easy re-assembly.

 
Line up the following two marks:

 
Now adjust the valves on cylinder number 1.
Factory tolerances are: Inlet: 0.11 – 0.15mm and Outlet: 0.18 – 0.22
Recommended settings for your inlet valves are 0.13mm and outlet 0.20mm. Nicely in the middle.

Line up the following marks for cylinder number 3:

Set your camshaft to 270deg

To do the clearances on the number 2 cylinder line up the T 2 mark on the crank and set the cam to 0deg.

To do the clearances on the number 4 cylinder line up the T 4 mark on the crank and set the cam to 270deg.

Please note: This guide was original posted by Mob Rules as stated above. I simply reworded it for (hopefully) better understanding.

PDF available if anyone wants it.
