Just to clarify. I remember reading that Pete set his valves at 6thou for intake and 8thou for exhaust.
I did this and while my GRiSO runs great, it is a bit noisy. My question is, is this best for the roller valve Grisos?
Or should I go back to 4 & 6 as the book says. Of course the book was for an older flat tappet model..

Enjoy the noise or doing damage?  scratch

Mine were set at a recent service at 4 and 6, with a roller conversion

4 & 6

However, if you run one of my maps, 6 & 8. After I've updated all of them to "roller maps", 4 & 6.

Clear as mud?

OK I AM running your map so I will stick with 6 & 8 and enjoy the clattering.

Just out of curiosity, why the more open setting?

6 & 8 is what my valves were set on when I had flat tappets, and therefore the maps.

Now I have rollers at 4 & 6, and there is a difference, so they will get roller updates.

OK, now I am confused again! Should I reset my valves on my roller GRiSO to 4 & 6 or am I OK with 6 & 8?

I have a vision of an 'Erudite' being similar to a Trilobite or maybe a Copralite Very Happy

Just checked my valves. Very slightly looser on the intakes and very slightly tighter on the exhaust. Tweaked them back to 6 & 8. Plugs look excellent. Life is good!

Looking forward to the roller map.

Thanks
