my engive vibrates a lot and i thing is from bad (or wrong intalation of) balance shafts, so is there anything i have to check to find out if its from balance shafts or not???

My motor mounts looks ok and my timing must be fine cos the motor runs and idles REALLY GOOD... so?? anything else i have to check for?

$th gen H22A btw...

 

check ur balancer shaft belt, its a smaller one u cant see, it sits by crank, its like kinda a triangle belt, the two shafts sit above the crank, that belt coulda possible broke or be fucked.

 

actually its a litle more than a month old so how can i check if its installed correctly?

 

You can check the rear shaft by putting the engine at TDC and seeing if the shaft is in the correct position through the alignment plug on the back of the block. To check the front shaft I think you'd have to take a few things off to see the alignment marks. Refer to the helm manual...
