"Engine vibration...Monkey AB27" > 자유게시판

I've written before that the snoring is bad above 6000 rpm.

Maybe this is because the engine vibration increases suddenly.

It's very smooth at 4000-5000 rpm, but when it goes beyond 6000 rpm, the vibration increases and you feel like you've hit a plateau.

(。´･ω･)?

Not only GPX engines, but Chinese-made engines don't reduce vibration unless you center the crank...

In particular, GPX engines for racing are said to vibrate violently and put a strain on the crank if you don't use a lightweight rotor.

I think the correct way to use it is not to ride around town, turn on the headlights and charge the battery, but to open and close the throttle on the circuit, rev it up to high rpm and compete for speed...

In cases like this, I think the problem is more fundamental than the carburetor settings or the CDI ignition timing.

(-ω-;) Hmm

When I'm racing without a load, it can go up to 12,000 RPM in one go,

but when I'm riding it myself and it goes up to about 6,500 RPM, it starts to vibrate?

As a last resort, I bought a rotor that's 35% lighter...

I wonder if a lighter rotor will reduce vibration.

Is it a case of giving up when you're even talking about centering the crank?
