Rocker bolt size?

[Svsam]

Evening all. 

 

I came very very close to making quite a costly armature mistake on my dot head build. Thanks to @Captain Chaosfor pointing out that cam caps are not interchangeable, the engine didn’t even turn with the wrong ones one. 

 

I am now set to fixing the originals by helicoil. 

Question is what size insert will it be?

thread measurements are anything between 6.8-6.9mm. So m7?? 

Who uses M7s? 

[1100fred]

Yes there m7  

[Dezza]

Yip, M7. Don't APE do oversized M8 bolts though so a more common M8 insert can be used?

Check through Clive's NWS slabby thread. I remember him posting a kit he found with the M7s.
