Super awesome build thread.
So nice to see an older guy flat tracking in his own backyard on such a nice machine .
hate to clutter up your thread with this comment, but in the pic of the oringed head, I didn't see the water control mod done to restrict the flow over the exhaust???
Hate to see you experience a partial seizure on the exhaust side, Which is why I ask..
Can you touch base if you did the mod or are you running the head as it is pictured with no adverse affect's ?
I would have to check with Rob and see if he did that or not. I was neck deep in the ATC250R build while trying to get the rest of the 500 powdercoated so I don't recall everything that was done.
