Ref your comments Mike...  I (think I agree) and yet when I bought my K2 it'd been fitted with a similar mudguard to El burro's. The odd thing was that the included fork brace was correct for my early K2 forks.... implying some (where in the world?) CB750s had these fenders?

Anyways all burro.... hope these pics of use.

Hi Billy,

The backfiring, lumpy, popping, plug blow-out are all suggesting (to me) a timing issue, and due that 4000 RPM threshold, perhaps a problem with the advance / retard unit... which is possibly 'stuck' in the advanced range? Check it's working properly, is smooth turning, the springs in good fettle, and most importantly of all, it's set up to the correct timing marks. And obviously, if one set of points is mis-set, that too will show up as a pair of mis-behaving cylinders.
(Ballpark, the advance retard kicks in @ 1100 RPM, and is fully advanced by 2500RPM.)

Apologies if you're familiar with setting up, but just to re-affirm, the static & strobe timing marks (low idle) are the 'F' mark, whilst above 2500 RPM or so the strobe should be illuminating at the two marks 23.5-26.5 degrees ahead of those F marks.

Er.... enjoy your Sunday!

Hi Dieffe,

Just going through my, er, inventory, today and found the below. They're off a non-OEM seat. Pretty good nick, just need a clean & perhaps rub of glycerin oil.

PM me if wanting them, again, beer tokens. I'm only here (England) til Mon arvo so get me your address ASAP if I'm to post them.

Cheers,
Simon

Ensure its V5C status is changed to 'Historic', but as Roy says, you still have the naus of annual tax application...

Beautiful... btw...

...just checked the DSS website... His reg / rectifier is a combined aftermarket part... same # for both 750 K & F series. Notably this part has the standard loom connector with included green earth wire.

So, I'm confused... and will have to bow out on this one!

Oh... that 5" strap??? its shape looks awfully like it connected the batt -ve to the forward most R battery cradle mount in your pic!

Still confused Graeme.

In your photo you've the fuse holder connector lowermost, and above it the rectifier connector. In the wiring diagram (my last post) these two connectors are reversed, ie the rectifier is lowermost. And it has a green wire.... (+ 3x Yellow + Red/White) which presumably is connecting into the bikes loom, and thence an earthing point somewhere?

At the mo can't think of what your spare 5" heavy duty cable might be, but by the eyelet sizes am wondering whether the PO connected the battery earth to a nearer point on the frame rather than the standard engine hanger bolt?

I appreciate the following is not a lot of help.... I was looking through the F1 difference wrt your rectifier earthing... but it's says nothing... implying the set up is the same???

Anyways,

From that photo the rectifier loom plug does seem to have a green... confused.

Just found this pic for the K series... luckily my earth strap correct. Wouldn't have thought the F would be different.

Hi Graeme,

Unsure... assume we're talking 750 K series? (I am!)

I can't find any specifics as to the positioning of the main frame earth, but for ease of servicing have bolted mine on the outside of the mounting bolt. In my pic below it is taped up ...

Might be confused (ie myself), but your rectifier is earthed via its connector plug into the loom of the bike. (Green). This green then appears elsewhere and is bolted to the frame - LHS panel, top LHS.) See attached pic with single scrawled circle. Its a REALLY CRAPPY photo - sorry - but there is a (green) earth eyelet bolted (outside) and going (initially) vertically down before looping up to the right. (& nothing to do with the #1)

Your spare 5" earth cable... is it a heavy duty one.... and actually the +ve from the battery to the solenoid?

A pic of my K2s battery area, fairly accurate methinks.

Ahead of you on that one Hairygit... for once. Assumed Ash was building 1/2 & 1/2 of 400 / 750 wheels. (36 & 40 spokes)

Well.... that's my story...

Um..wheels... I kinda got this feeling you'll build some contraption, stick it in the airing cupboard with 10 rims + 380 spokes.... go to bed .... and thence come down to brekky with all miraculously done.

Fantastic Ash. Love this kind of 'tinkering'.

Not to throw a spanner etc, and one who's fallen foul of a (bloody careless) petrol spill on a beautifully painted tank, ... but is the epoxy ok in this respect?

Bit of a soak & then "Test #2"!

CB350/400 / Re: 400/4 missing breather chamber
« on: March 15, 2015, 01:28:03 AM »
Prob to satisfy elf'n'safety, on the later CB750s K's this breather was routed down a swing arm & off to the side... ie so not venting (oil mist) onto the rear tyre. I suppose ensuring it's sited to one side & points L or R might be something to consider...
