The dial-a-dome has always intrigued me, but my curiosity was never worth the price tag they were looking for.

The concept is simple, just move the crown of the dome further or close to the piston. But do they move the WHOLE crown, squish band and all?

The dome area is the only part that moves, I had a set on sled motor once they worked reliable for me, I always adjusted them after the motor cooled down and always assembled the domes orings with silicon grease so the domes could turn and not tear the orings.

Ultimately you want the dome when screwed all the way down to be you race setup for what ever fuel you normally run then back it off for safer reliability when just trail riding and cruising.

when backed off, and giving you less compression there is a hard edge going straight up this edge does get a little warm because I use to get a little carbon marking at the edge and heat is how that happens, but I never had a detonation issue because of it.
