Nice job Prokop!... I'm also planning the same assembly process.

Are you using the original engine hanger bolts?  One of mine is pretty bent so I was trying to find good alternatives.

Thank you  :)

I am scavenging bolts and brackets, will be making some pieces and ordering from McMaster, I have several bolts for the front, but the one for footpegs is like 4 inches longer, not sure where that came from.

I had the engine out this way but the wheels were still on. I'm seriously considering assembling the top end in frame now that I have Gordon's kit installed. Previous plan was to do what you did above, but with the wheels on first, so the engine could stay off the ground. I don't have anything to hold the bike up except its center stand. Nice progress!

Prokop your bike is looking very nice!
 
I am trying to find the Gordon's Kit or something like that, any idea where they are available?
thanks, Mark

Good question, don't know the answer yet.  I have 4 single pipes I could combine into some kind of a 4-2, but it depends how much energy I have left when all the rest is done.

Since this is supposed to be long distance hauler with fairing or at least windshield I would think 4-2 would look better on it,  but I may end up just smacking Mac on and calling it  :)

No no no Mac! You can do better for the same money finding a deal on a good used system.
Reason I ask is obviously the exhaust will determine jetting. I know will be running pods!

Stock air box for sure, if I can actually get it installed, looks like carbs and airbox together are major challenge.

Thank you.

 I will be replacing them with tubeless comstars in the future, thats the whole purpose - wheels with minimum maintenance needed.

But the bike will be like giant quiz - how many different years and makes can you spot:)

yeah, that stuff is fun with these years of Hondas.  At first your surprised by how much doesn't inter-change when you suddenly realize that other surprising parts do.

Installed brake pads. I really like the identical calipers front and back. Smart solution.
