unfortunately some people burnt this guys shop down so he isn't workin on the pipes anymore that i know of.

 

DS650Stage1,
(SPD)speciality performance designs is a production shop,I stopped in one day the owner was out but talked to his wife and her first response was they didn't do small jobs.But after talking to her for awhile(told her I was a neighbor) she said come back when her husband would be there (and bring the DS) and he probably would take some interest in my project.I have a few street rod friends,they said the guy would work with me.
When I get my DS back together I will make another visit to SPD,and DS650Stage1,I will let you know what they could do for us.
I would think with a dual exaust set-up the silencers would be smaller then the normal size.

VEGAS650,
Actually that makes some sense,the oil will tend seep out to the breather line when the counter-ballancer stops moving.With the breather routed through the ballancer oil is kept out by the centrifugal force...thus when the motor stops oil will flow out the hose to the level matching that in the motor.
My thoughts at least.

My oil overflow problem may have been related to 2psi of crankcase pressure.

I had 7% cylinder leakage.

Piston has bottom 2 piston rings broken.
