Found this sohc for pennies on the dollar local listed as a different bike! Looks like a 77-78 F model with a k tank but the rear fender have me scratching my head. fender looks k of course but not with comstars. The flat shifter also says f so maybe an f engine with....bah I give ! The k tank and that seat mate up too also throwing me for a loop. Someone smarter please speak now or forever hold your peace. Said too have a vance and hines drag exhaust...Picking up tomorrow if compression numbers check out.

Looks like an early bike with Comstars grafted on to me.. Cheap parts bike...

but keyhole carbs...

Front brake caliper isn't late F. Also, late engines were black. You'll have to check both the frame numbers and the engine numbers to know for sure.

Frame says K frame..

hsas.69 · « **Reply #5 on:** March 27, 2015, 07:26:17 PM »

Not an expert but I would guess its a 78 K that someone put the comstars on. Those are the later model reverse comstars not what would have come on a 77-78F

78whiteorbs · « **Reply #6 on:** March 27, 2015, 07:28:10 PM »

Yeah I see that now. K frame... didn't know you could run comstar rears on a k . Thought they were all single disk.
Really would love to see the other side. . 77-78 k would have keyhole carbs but that's an earlier k tank and the seat mates up. Somebody could have slapped those carbs on that engine. Guy wants 350 for it said great hcompression . Pretty firm.

"Those are the later model reverse comstars not what would have come on a 77-78F" good eye that's right Now that I think Of it. What could those comstars come from?

I think the rear peg mounts may be 76 or earlier frame type
I bet the front brake pads are only partly contacting the rotors, ie part of the pads are grabbing air..

Wheels look like early 80's cb750 Custom. Probably used on other models also.

If it runs good its worth It, ride the piss outa it a few years, turn it into whatever you feel like.. Could be fun..

They're all not destined for correct restoration, a hot rod 750 can be a blast to own. Put on whatever parts you want. Or not.

Tugging on my heart strings- well I at least have to go have a look right...

Lurch77 · « **Reply #17 on:** March 28, 2015, 06:57:56 AM »

Yep. I'm with the others. The best thing about a mutt bike is that you have no guilt about chopping it, bobbing it, cafe'n it, etc. You're not ruining an original bike. If the price is right, that could be a fun project bike.

I remember a story from Canada many years ago, about a guy that had a tubbed 1969 Camaro SS. So many people were upset that they guy would do that to such a collectible car. But the guy bought the car after it was totaled. It was no longer going to be original anyway. So he said, "what the hell", and had some fun with the car.

78whiteorbs · « **Reply #20 on:** March 28, 2015, 02:17:14 PM »

I figured the motor carbs exhaust and tank was worth that.
Had a vance and hinds sidewinder 4-1
Compression felt good to my boot. Extra set of finned covers an extra valve cover, a bikini fairing, extra set of side covers and few other odds and ends. Not sure if those PD carbs are gonna work with that engine but maybe it is a k - engine with just an earlier oil tank...the wheels are a mystery. Everything looks to line up great frank-. Maybe they swapped forks and all . Try and post some more pix . Especially frame and engine numbers to try and decode the year of each. The engine is a coat of many colors. Chrome at first then blue and something Else. Looks like a prime candidate for some wrinkle black :-)

Stev-o the drive was worth it to see this at a truck stop.
Fried corn on the cob.

78whiteorbs · « **Reply #22 on:** March 28, 2015, 02:19:46 PM »

Here's some more pics cause everybody loves pics

78whiteorbs · « **Reply #23 on:** March 28, 2015, 02:23:00 PM »

I have the side covers too Just took em off for the drive.
Gonna hook some cables up and squirting some carb cleaner in there in a bit and see what happens. Dude said carbs had been cleaned and stored inside .

cb650 · « **Reply #24 on:** March 28, 2015, 02:32:47 PM »

No mystery on the wheels. Reverse comstars someone made work. On many hondas from the 80's. stock on many sohc4 650s.

Stev-o · « **Reply #25 on:** March 28, 2015, 02:34:05 PM »

You musta really liked the corn. Good score, bike not the corn!

78whiteorbs · « **Reply #26 on:** March 28, 2015, 07:21:04 PM »

well engine runs! The comstars look to be as if they were stock as far as fitment. No evidence of spacers or any milling anywhere. Never seen this combo before. now it's to by this poor orphan some new shoes and give it a bath.

78whiteorbs · « **Reply #27 on:** March 28, 2015, 07:23:00 PM »

Sadly it has been abused and there are scars.

Correct. Engines 3000001 and subsequent were K8's.
Frames 2800001 and subsequent for K8's.

I have the manuals specific to the 78 on a Google Drive that are shared out. You're welcome to download them.

Looks like the frame as cut for a Gordon's Frame Kit.

78whiteorbs · « **Reply #32 on:** March 29, 2015, 08:00:52 PM »

2552887 frame number. Looks like a k6 frame.
So somebody swapped a 78 motor in a 76 frame. Right fork has same provision s for caliper as left. Looks like there use to be a right disk on there as well. So that's kinda cool for dual disk upgrade if I can find the right caliper.

scottly · « **Reply #33 on:** March 29, 2015, 08:09:23 PM »

Let's see a pick of the caliper mount, please.

Don R · « **Reply #34 on:** March 29, 2015, 08:16:37 PM »

Nice find, could turn into a decent bike. My K0 is a day 2 restoration, like someone would have built it in the 70's. I had guys whining about my 40 chevy being a street rod, I mentioned it being saved from the scrapyard and how it's been a hot rod since '58.

78whiteorbs · « **Reply #35 on:** March 29, 2015, 08:21:58 PM »

Thanks Don, it sure has ahem, character.
