I checked everything on the engine.
I also checked the rotor cap and internals.

Everything is fine in the rev range but when I start to hit high revs (4500rpm) the engine starts to make small vibrations that gets more as the revs increase.
Basically as I explained in the previous post.
Like a hammer drill you press against the wall to start drilling. You can then feel the vibrations on your hand as you drill.
It is sort of the same vibrations.
I would just like to know if my engine is out of balance or if this is kind of normal vibrations maybe even harmonics coming from an engine that is not balanced.

What I am compairing to is modern cars of today. I drove the other day a volkswagen polo and the other day a Nissan Almera and revved them to 6000rpm 6500rpm.
They where nice and smooth. Am I wrong to compare a 25 year old car to new technology?
