  They do look nice . But I wonder if they are close enough to the oil filter to heat it up , they don't look like they offer air circulation around the filter housing cooling fins.  And  looks like it blocks the filter bolt making filter changes even more joyous then it would have to be. I was thinking that you wanted to have deeper sump  and a cooling radiator to keep the temps down ....now because of this header design, you have neither of those things working for you, and it isn't the one you ordered? I'd send it back and so you can make the machine that you intended to make.

    It does fight tight, maybe too much, there's little to no room between the oil filter and the header. I might try two sets of exhaust gaskets and see what effect that has with the spacing from the oil filter. My main problem is, this pipe leaves no room for the oil cooler or the deeper 650 oil pan and it would take another 8 weeks or more to get the sidewinder. So I'm more than likely going to get another pipe over the winter (not a carpy) but for now I'll use this.
     I haven't any idea if its fat or lean, just rode it around the neighborhood, it not registered yet. It has 100 mains and 40 slow jets. On the up side, it does sound soo much better. Packed and wrapped the baffle to keep it as quiet as I can.
Start with the end in mind...

So I bought these on ebay, $85, free shipping, how could I refuse. They're from a  79 kz650,  they cleaned up rather well, just waiting on a fuel pump kit and new bowel gaskets. When time allows after the holidays, I'll see whats involved in getting these properly mounted. Any input would be very appreciated.

    Well, I'm not sure, but they're a touch larger (24mm) than the stock units which are 22mm. Will need to fab up an intake adapters to get them to fit up. Will have to use the manifolds from a kz650 and then an adapter plate between the head and the kz manifolds. Or, if anyone has any had any experience with this type of modification, I'm open to suggestions.

They should be an excellent upgrade  8) even though it'll take some modifications
