Possible engine damage?

[Romeo]

I am looking for opinions and input here.
Does anyone think running the left bank of a Valk engine with the cam one tooth off could cause damage to the crankshaft and/ or crank bearings?
The compression on that side was 50 psi less than the right side while the cam was off.
Now that the cams are correctly positioned, the compression reads just norht of 170 psi at all six pistons.
The reason I ask is because of the god awful sounds emenating from the motor.

ONe tooth shouldnt make much of a difference and should not cause damage over a short time.
What God Awful noises is it making?

I ran mine that way for a day until I figured out what I had done...no damage to anything just one tooth off

Probably the cam belt tensioners are too tight.

I rode the bike last night and they are some weird vibration/ noises that come from the bike...

But pretty much only under load......

If you pull in the clutch while rolling they go away.....

Once you get up to speed... they minimize....

Not driveshaft, u joint, front rotors (that was my first thought until I got rolling and pulled in clutch),  etc,

My vote is bad crank bearing.... Or clutch????? or Tranny??? LOL

That why he's asking...

Or, the cam belt tensioners are bad. (One or both)

I agree with the others on this.  I replaced belt on a 97 that was one tooth off from the factory.  ran good before and after   Michvalk has it right.  Belt tensioners dirty or bad bearings and most likely the belts too tight.

I can't imagine any internal engine damage and the compression is good so the top end should be fine.

I too am thinking incorrect tension or a bad tensioner.

Does this monster have any modifications  such as an aftermarket trigger ?

I replaced my timing belts shortly after buying my bike and found that one sprocket was one tooth off. I had ridden the bike for a thousand miles before replacing the belt and I have no idea how many miles the previous owner had been riding it that way. After getting the timing right, I noticed no difference in the ride at all. I was actually surprised at the fact that I didn't notice a difference. I was expecting something significant to happen.

Thanks for all the great input, guys. I will for sure look again at the tensioners. My question is, if they are bad or too tight, why wouldnt I hear the noise at idle, or at least while revving the engine in neutral?
But, I am for sure going to loosen them up, if I can and give that a try.

Honda says to set the tension/slack at about 1/4". To me thats too tight and makes them too noisey. I set them at 3/8".
Seems I remember seeing some Goldwing spec saying to set them at 1/2".

I pulled the belt cover and adjusted the tensioners, all the way slack. I measured the slack in the belt on the opposite side from the tensioner and its barely 1/4". Can someone explain what the spring is for since there are two bolts holding the tensioner in place? Anyway i took the bike for a spin and still here the noise eminating form the motor, although it does seem to be slightly less annoying. Again, thebike sounds perfectly good idleing in the garage, I only hear the noise while riding and the motor under load.

[Ricky-D]

The cam belt tensioner spring is there to use as the necessary force for adjustment of the cam belt tensioner pulley.  How to do it. Remove all of the slack from the driven side of the cam belt allowing the spring to pull against the loosened cam belt tensioner pulley, thereby taking up all of the slack of the trailing side of the cam belt. No additional force is necessary to help the spring against the tensioner pulley. Tighten the cam belt tensioner pulley while maintaining the position of the tensioner. The spring only. Forget about any measuring of deflection of the belt because this is not accurate.
