Greetings from Florida!
« on: February 06, 2015, 04:35:21 AM »
Good morning everyone!

New member here posting up!  Been in motorcycles for quite awhile now, and picked up my first SOHC.  Pictured below is my new-to-me 1978 CB750F Super Sport.









Got it cooking on 3/4 cylinders with starting fluid, digging into the carbs now.



Cheers,
Adam

Welcome aboard! You might want to start planning to attend the Manufacturer's Cup drag races in Valdosta in April:

http://www.manufacturerscup.info/?cat=37

We have a strong contingent of members here that attend (and even race) at this event. Excellent track, and even better company! From Gainesville you could drive up for just one day at least, just look for all the SOHC/4's.

Thanks all.  The bike had been "worked" on by a "shop"; they totally took the PO for a ride, poor bastard never even got to ride it.  Now repairing the "work".  For instance, bike came with 1 throttle cable, choke was upside down and backwards and twisted on, and it has a HD Sportster exhaust.  Might be a few more surprises :-)

P.O.'s (previous owners) are bad enough, but when I see what some of these mouth breather's that call themselves "professional" mechanics can botch and hack mechanically, really makes me wonder. I'm currently whipping a 1997 Suburban into reliable condition that happens to be one of the most mechanically neglected machines I've ever come across...

and that's compared to a 1978 F250 crew cab that I had that was being used as a dumpster when I got it!

Wow...

just freaking wow.

You got me beat... my current project only had four different types of screws in the carb bowls. Looks like you've got at least six different types of screws! I have gotten pretty good at Helicoil repairs of the bowls screws though.

After seeing the outside I was...apprehensive.  But it looks like the shop just did a carb clean and replaced the bowl gasket.  But since cylinder #1 isn't running need to make sure I double-check that carb.

If that model of carb allows the removal of the emulsion tubes and jets without breaking anything, I'd pull them apart and carefully inspect them for stock Honda brass, and verify that the jets haven't been drilled. Just worked on a set with a member who's stock 38 slow jets were drilled to about 60s. No wonder the bike fouled plugs after idling 3'...

They're pulled and look unmolested.  Thankfully.
