    Ultra 150 balancer removal

    Has anyone ever removed the balancers from the ultra 150? I am well aware how the oiling system works on this engine and also how the balancer system works. Please don't post replies like "why would you do that?" and such. Useful information only please.

    I am really thinking about it. If they arent there for handling dangerous harmonic vibrations in the crank and are only there for comfort & driving the oil pump, I dont see why they would be needed in a full race application. Can anyone chime in? My winter build is going to possibly entail removing them amongst other mods that I consider "out of the norm"

    Yes it is possible to do. You should give steve a call at skiworx he can give you more details about it. Some of the factory kawi race boats had that mod to help the motor spin up faster. I wouldnt call it a rec friendly mod but in a race application it would be fine.

    Ive recently done it and you must have the crank balanced and have pistons weighed to identical spec.

    Great, I sorta figured that. Nice to know people are doing this and its not causing harm. We can lose a lot of rotational mass here not to mention clean up the oiling system and go premix much easier.
