Eliminated the balance shafts in H22!
After lots of thinking, and consulting with a few engine builders and people who are currently running without balance shafts I have succesfully eliminated my balance shafts in my h22 engin! First off there are 3 bearings that each balance shaft rides on. The rear balance shaft runs on 2 bearings in the block, and a third bearing in the oil pump casing. The front balance shaft runs on 3 bearings in the block, and then sticks out of the oil pump casing.
All that is needed to to to the bearings that are IN THE BLOCK is to turn them so that the oil holes do not line up, therefore blocking the oil flow to the bearing and not losing oil pressure. *The bearings need to be slightly modified to be able to be turned, because they have locating tabs to prevent them from spinning, I am working with trying to make the modified bearings available, otherwise whoever does your machining for your motor can easily do this! Then the last bearing in the oil pump casing for the rear balance shaft needs to have a plug pressed into it, and same with the hole in the casing for the front balance shaft.
These plugs are now readily available for $40 shipped through my roommates machine shop: Control Tech, and the subcompany AlienAutotech. The plugs were a perfect .0005" interference press fit and I pressed them in myself with a cheap press from Harbor Freight. Instead of hassling with finding the correct freeze plug and having it be ghetto, this kit is beautiful.

Sorry for the dark pictures!!!

They covered this topic in a recent issue of honda tuning (my Favorite mag). They said eliminating the balance shafts would free up a few extra hourses by getting rid of some parasitic drag, much like the way Pulley kits work. But on the down side the iddle will be rougher and in my opinion is not worth it.
I will post as soon as the motor is running, I am still waiting for my C&R radiator to show up and a few other parts, then I will let you all know FACTS about how the motor acts without the balance shafts.
What do you mean FACTS? are you saying honda tuning magazine does not have there facts straight? your just trying to sell something

I thought balance shafts are designed to smooth out the vibrations when the engine is accelerating or decelrating, Ie balance out the vibrations, like a Harmonic Dampner?

And no I am not trying to sell anything, my roommate is the one manufacturing the part, I am just trying to post useful information and hopefully be able to solve a need for a part that so far is not in existence!

I mean that everyone seems to be stating what they heard, or what they think the engine will do. I don't care if Honda Tuning prints whatever they want to print, I am sure they are eliminating the balance shafts, but unless the author of the article has personal experience with an h22 without balance shafts then until he does, he is just another kid who is printing what someone else told about how the engine will react without balance shafts. Hell, I don't know for fact, the only thing I know is also what I heard, until next week when I start mine up. I will be sure to let you know. I know my good buddies 4g63 engine runs beatifully without them and has done so for quite some time!

I am sure your h will run fine with out the shafts, you will get a few extra hourses, but your idle WILL be rougher. The balancer shafts are made to smooth out the idle. Its not worth it imo.

I suggest you read the artical in hunda tunning because you will find it was not a "just another kid who is printing what someone else told about how the engine will react without balance shafts" but someone who builds h's for a living and not only does he wright about the balance shafts but in the artical he builds a h22 with out the balance shafts.
I am sure your h will run fine with out the shafts, you will get a few extra hourses, but your idle WILL be rougher. The balancer shafts are made to smooth out the idle. Its not worth it imo.
