I wish the welder would call! I hate waiting..

lol...i hear ya!!! so far it looks great!!!

GOT IT! Looks pretty good. Overall I give it a B+, the welder and I both learned a few things about the design and the inherent troubles. The great news is its burned in VERY well. Pics

I hope to have it cut for a bearing and faced off tomorrow or Saturday morning!

The more I read and see on this site, the more I feel like an idiot!

That is incredible!

Excellent work! would love to have the pocket change to do a crazy re-engineered build. Cheers to you for doing a CR500 right!

I am pretty happy with the progress, I am working with RSSS on E2S.COM to come up with a user friendly counter balance system. The spinning counter balancer weight needs to be able to be adjusted with in reason to be at bottom dead center with the piston at top dead center. I am hoping to get it timed perfectly one to another using test indicators on the piston dome and the bottom of the C/B system.
One of the goals is to design it in a way that doesnt interfere with local frame rails. That means keeping it shorter (legnth the assembly sticks out of the clutch cover case) I know by keeping it shorter the cost of getting rid of the maximum vibration possible climbs alot as you have to use VERY expensive metals to make the counter weights out of, but I want the system to appeal to everyone from dirt bikes to kart riders and all the motor heads in between. I also think mutch of the ideas shared on the E2S thread I linked at the first post of this thread can help eliminate the last of the vibes that this system doesnt.
The angle you mount your engine at, the mounts you use, the type of metal used and every other factor in between decides how much vibes you will experience to your body, take an old frame and hang it from a garage rafter by mig wire, hit it with a hammer... RING RING RING.... Now, add a gusset or a support bar and hit it again.. RiNg RiNg RiNg.. see... This system I am building will eliminate that egine frequency that is causing MOST of the vibes that numb your hands, with that being said it will create a forward and a backwards (front to rear bumper) vibration, nothing can be done about that. It`s part of the mechanics of a single cylinder system. When the crank lobes are at 3 and 9 the weight of the counter balancer with be way more than is needed to reduce the small amount of forward and rear vibration but when its at 12-6 the weight will be able to dampen most of that effect. Adding more weight to eliminate one makes the other worse. So it`s a trade off. NO SYSTEM gets rid of all of them. The rest that remain have to be lost by chassis design and other ways. Hope that shines some light on the egg head part of the design.
