That sucks about the delay of your order. I'm not crazy about the gas tank outlet either. I routed mine so it gets slightly lower as it crosses from right side to left then once on the left hand side, straight down.
I ordered another 190 from motorkit yesterday. It was under $700 shipped.
I'll never be able to fix the transmission properly in time to ride this season and nobody else will work on it. I almost got the KP then decided this was a better less expensive option and I could practice wrenching on the inside of the old engine or just sell it for $400 or something.
