I'm legit convinced it's just an updated version of the 47mm. This sucker doesnt have any spacing issues and clears the exhaust port easy with a normal ass .5mm base gasket. No weird squish issues here either. Appears to be less hi comp out the box too. Wooohooo. Things are coming up millhouse.
Performance is about the same the 47mm. Pretty damn tame. Good for a bolt on upgrade for those hoping to hit high 30s.
Last thing. Shakes a lot less than the 47mm. I cant confirm yet but I think motor mounts are gonna last a lot longer than previously.

Easy to install on your av88. Bolts right up. Hopefully you purchased the bigger carberator too.

Cylinder bolts right up to the AV88, stock variator works well with this set up. Would highly recommend replacing the gurtner with a slightly larger carb if you go this route. Good luck!
