Thanks Bill. The hardware has to be in the correct locations before I can pull wire. And I've got lots of wire to put on this bike.

Unfortunately its not for the red F model. Building an engine for the project F. Keeping my fingers crossed the red one has another race left in her. You won't see any record setting numbers for the F3 but hopefully the new F1 will chart new territory. Go, or blow. Lol

Doing my best to make  some progress every day.  While it might seem insignificant at first glance, the little bit I did get done will now set me up to move at a quicker pace. I had to relocate one of the nitrous solenoids on the mounting plate to leave room for the mono shock dampening adjustment. Also made a plate to mount some of the electronics. Got the rear brake line run but haven't juiced up the system yet. Finding a decent place to put the electronics will allow me to start wiring this thing up by the weekend. I only want to do it once.

Moving forward!!

Sorry for the ignorant question...but why 2 batteries?  do you have the electrics split off into 2 independent systems?

Not one thing ignorant about your question. I intend to have onboard starting with this bike so i set it up for 24 volt start. My original intent when I began this project was to build a very high compression engine using modified KZ high compression pistons with an F3 head. I simply wanted no problems turning the engine over with the stock, unmodified Honda starter. The hybrid engine has been sidelined and I'm currently building a K head engine using 12:1 MTC k model pistons. I'm certain it will crank with just one battery but it'll still be wired with both in series to the starter only.

Current status. 6 days remaining and counting down fast.  If all goes well, it'll be making it's first pass on Friday at Valdosta. Keeping my fingers crossed.

Sticking a 327 stick in it? And you just had to mention 6 days which means I'll be leaving the island THIS Wednesday…..

I just bolted the 327 onto the journals. Running short on time so I didn't do my usual clearance checks with a checking spring so not certain what my PTV might be until I get the rocker arms in place. All else fails, to make the race by Friday I will install the stock F3 cam. Stock cam won't set any records by at least my brother can have a bike to race.

Hey Billy, I just had a flash-back to the square-finned Maico cylinders from the late '60s/early'70s. ;D
Is there going to be internet coverage of the race?

Only 2 working days left and the engine is still sitting on the bench. But hey, I'm still making progress  :o. I'll have to set a drop dead limit on this one. I still have other running bikes to get ready. Beyond crunch time.

I unfortunately ran into a chain alignment problem and had to delay this project until after the Cup race. The F2 cases don't require an offset sprockeet and I didn' t have a stock one on hand.  Hoping to get it started up by the end of the week and to a track to test soon. We'll just consider this set back a head start moving into 2019.

Yeah, you may not be moving but you sure are stylin'.

So how does THAT swingarm compare to a Honda arm early or late 10mm offset width-wise.

Thats a chromemoly hayabusa mono shock arm. Can't remember the exact  length but it's at least 16 inches longer than a stock arm. It will fit inside the Honda frame with thin spacers. You will need to have bushings made to fit the arm to the honda pivot bolt.  On a pre- 77k/F, you will need a 10mm offset sprocket. Not required with the 77' up bikes. Bill brought a stock 17tooth and the chain alignment is close now.
