Ran across this video on Youtube yesterday, maybe Im the last to see it since Im just now getting back into the game after a few years away from it, but if this actually works like this fella says, Im gonna take all my engine down and use the technique on all the cranks since a badly balances crank can definitely be a comfort and top speed limiting factor with these little engines.

Is anyone else here familiar with this?

Has anyone else here given this a go to see what their results were?

When I have time, Im definitely gonna give this a try on a particular engine I have on one bike that has bad vibes.

I'll also check and as much as possible correct any wobble in counter weights

even if this hack only took 50% of the vibes out, that would add performance and better potential longevity to one of these engines since some of them vibe themselves to death after a while when they used for WOT cruising like many of us do.

If it works good on the one engine, othwr O have will be taken down and the same will be done to them also.




Hmmm interesting
