I've not noticed any loss in cut power from a light flywheel,usually just gains buy I've never tried one this light.Racers do that for cookie cuts ,bad for a working saw ,i would add weight on a work saw .
I like the flush mount pull handle ,cleans up the look of the left side .
It may run hotter without the extra cooling fins ,i only run longer bars so what i like in a saw is different than a lot of the rh coast likes .I've not noticed any loss in cut power from a light flywheel,usually just gains buy I've never tried one this light.
It was a broke flywheel so I done that,useless the way it was.
I hate the handle in a husky, always in the way tuning so I cut the damn thing off shorter
