Thanks guys.
@mopguy: I like the 750H as well. Spent a bit of extra cash getting the handlebars rechromed as I didn't want to make any compromises on the riding position. My daily rider is a 2012 Hornet with a wide street bar - bit of a different story!
@nessism: Oh well, I guess we'll call this the Athena experiment
I've had good experiences with Athena in the past... If anything fails it's not too bad, Nothing that will require splitting cases. TBH I got the gasket set from Athena as it made a few hundred dollars difference compared to OEM. The oil pan gasket has been fine for about 6 weeks with oil in it :whistle:
EDIT: Saw your post on Athena gaskets. [strike]One good thing may be the fact that the base gasket isn't the same green gasket as the clutch gasket etc. It has a different texture that feels more like what I use on the Mini. Also, not green [/strike] Looks like I was getting confused with the valve cover gasket. Can definitely see some green between the cylinders and crankcase... Let the experiment begin

Here are some photos of the repair I had to do on two of the exhaust stud holes. They split when I was extracting the bolts (got 6 out with heat and patience, two of them just wouldn't come out). The first photo isn't very good but you can just see the hairline crack. Ground out the side walls with a dremel and got a local guy to weld them up for me. Then spent lunch time at school in the woodwork room throwing together a rig for the drill press. Used some long 6mm threaded rod to make sure the holes were in line. Studs ended up perfect when I put the exhaust on.

Cleaned up the coils and replaced the leads and caps (NGK). Took a page out of Nessisms book and reused the sheaths from the original leads.

I rode one of those for awhile while I restored my XJ. Was a fun bike and it's cool to see one getting restored! There was a member on here that had a NOS complete exhaust system on here for sale, it was awhile ago but might still be available if you were looking to go that route.

That was me and it's still available, but he already installed a new Delkevic system. in case somebody else is interested. hee.

Yessir it was. I was just mentioning it as I know some resto's have received aftermarket exhaust simply due to the fact it is so hard to track down NOS exhaust stuff.

Thanks guys. I was interested in an original exhaust but all of the ones available over here had a bit too much rust for the cost. Now that I have the Delkevic I've blown my budget
Especially if I needed to get it shipped from the US!

Carbs reassembled. New stock jets, zinc plated parts (choke lever and the two main brackets nickel plated) and new chromed tops. Polished up the carb bodies as I cant stand the matt grey finish. Not the best polishing job but will hit the outside ones with a dremel when everything else is done.

Question for you guys about the throttle and choke plates: I used green (2701) loc-tite and lock washers instead of staking. I figure once the loc-tite has cured this will be bomb-proof. Thoughts?

I've used loctite on all my carbs for the throttle plates with zero issues over the years. Heating a little to remove later (if I ever have to again) beats filing the back of the screws off.
Never used green before but after reading up on its application I don't think you'll have any issues.
Your carbs look great!

Thanks, that's exactly what I wanted to hear 
I'm pretty happy with how the carbs came out. Hoping I don't have any issues when I put them to use!
