Honda-SOHC

Thought I would enquire on the off chance that someone has spare.

Ideally painted in great condition 

Original colour preferred.

Alternatively, any recommendations on reasonable priced painter for repair and paint tank and cowl to good standard.

Thanks

I see DS are doing the repro K7 pipes, not sure if they are from Busso?

Maybe DS will do a repro silencer to fit the OE pipes, assume unit cost will come down on shipping in bulk.

I did buy a NOS collector from CMSNL but was about £750, I have one of the seperate pipes, a NOS large clamp  and one pipe to get .

Probably be afraid to fit them 

If you dont have a parts book to see which parts split worth checking https://www.cmsnl.com/honda-cb750f2-super-sport-england_model14689/partslist/

Thanks Guys appreciate your comments and suggestions

Another electrical problem as not charging

I had fitted a solid state regulator/rectifier so suspected that,

One of the quick checks is to see if the field winding screws on outside of alternator case are magnetised with ignition on, meaning power is going to field winding.

If the battery is at higher voltage or too low may not work as regulator not calling for charge.

You can use a metal screw or bolt on the screw heads.

In my case not magnetised.

Swapped  new solid state reg/rect for a spare original, but same problem.

Suspected field winding, but resistance within spec between white and green tested at sub loom.

Mmmm maybe the old regulator is faulty, so tried another spare, but same problem.

Checked continuity on sub loom and earth and switched power to regulator.

I had disconnected sub loom that connects main loom to alternator and this was also new.

Checking the orientation of wires and noticed that the White wires did not line up !!

I have the old loom and the new loom from DS had white wire opposite to original.

Removed the White wire after depressing tang that holds in block and refitted in correct position and connected everything.

Now the field windings are magnetised 

Hope this helps other with problems with repro parts.

Handy link, thanks.Do any of the Keihin carbs fitted to CB SOHC/4's use screw in jets 🤔

Yes the main jets on CB750F1 and CB750K8 PD carb do for certain.

The PD carb slow/idle are push in.

Genuine jets are expensive but Motorcycle Products do sets of 5 for £7.68

Keihin 105 Brass Jets

    Head size 6mm
    Thread 5mm
    Pitch 0.80mm
    Overall length 9mm
    Thread length 5mm
    Made in Japan

Many other sizes and for other carb manufacturers

Ideal if you need to try different sizes

I managed to clear obstruction without removing by using carb cleaner and compressed air.

Changed main jets  to 110 from 125 and one 0.4mm washer under needle clip.

Now runs fine
