Default Re: Speed & insane vibrations

Tom is dead on right here, there are other factors involved beside just the crank balance, my dax Gen IV engines set up the same as my other older ebay engine have about half or less vibration though, they don't even buzz my hands, and turn way more rpms and actually get smoother the higher they rev rather than the opposite which is how my other engines are which get insane vibes at higher rpms as if they are gonna fly apart at any time....LOL! and those kind of vibes limit power and rpm if the engine is that out of balance.

Great points Tom, all of those things need to be done right not only for dealing with vibes that may come from things not being mounted correctly, but having all that stuff right is gonna add better reliability to the bike also.

I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
