yes, good opportunity to restore some parts and repaint the engine, I did rebuild the engine and replaced the camchain/sprocket and primary chain with original DS parts back in 1988/90 approx 40,000 ago, but didn't replace their tensioners they looked good. 40,000 on a camchain? lifespan of a camchain? with oil changed every 1000mls. It has taken a bit of a thrashing when asked though, and never complained.
 Was hoping some of the gears would match,  looks like a full rebuild then.. dissapointed I only got 18 trouble free years out of it ..It spent first 8 years to 96 in my room, should have kept it there!

Ok cheers lads.. just assessing next step,  I see now I have the option to whip the lower crankcase off without disturbing the top end, that's handy....I'm considering if thats all I should do? or a full rebuild? ...because I've had an on/off low down at the front clatter/rattle thats been worrying me for a few months, and have been thinking its the camchain guide or tensioner pulley,  I'd notice it only in first gear, just as I let the clutch out to move slowly forward parking, and occasionally at idle, would this gear problem cause intermittent noise?

And anyone know if the later K model gears are interchangeable with the K0 gears?

 yes thats it alright.. will it be okay to run, until I decide if I want replace the affected gears? been no trouble with the gearbox,  think I possibly I did this last week, when putting it in gear at traffic lights and I got that rattle /screech when I messed up the change.  Dogs and gear clusters, what does the dog do??  don't think they transfer power?

Hi all,
Was changing the oil and filter today, and had a look in the sump pan, found this piece of metal, thank you Santa....been over 20,000mls since I last had a look in the sump, was expecting some residue in there, looks like there's black bits off the camchain guide, and some small bits of metal, not many, and this chunk of metal which looks sheared.
The bikes running and starting fine, though there has been an on off rattle, low down at the front of the engine, seems to have gone.
Any ides what this chunk of metal might be? and the prognosis? dreading this... part of the tensioner assembly?

I Kept it simple and made a lead with a spare plug cap, copper cored ignition lead and bullet connector. It worksfine with the spring connected, easy on no4, 3 was a pain with the engine & pipes hot, have a couple of small blisters to prove..burned again, wont post the pics! now see the benefits of the clip on pickup! may still try that method,

Nice one again, just recently found my colourtune kit too, tho the adapter's thread is smaller than a standard spark plug's, if I find a spark plug ferrule may still be able to use it, will check this out over the weekend.

Hi Simon
Nice, I'm thinking the fly lead fitted to a plug cap could be the way to go, and could also use it on 1 or 4 cylinders.

cheers

I've got a few spare plug caps, if I can figure out something like that, Its just getting the extension between the spark plug and the existing plug cap somehow, If i can get my head round it, could possibly do that.
Will look into these and update.

cheers

  that would do it, I wonder if that later style clamp is available, is it a special kind of inductor? could you post an image of it  please.

cheers

CB750 / gunson's tachostrobe

Hi all, thought I'd give the forum a try,  I'm trying to double check the timing on the Honda with my trusty old tachostrobe, I can get the Gunson's universal spring connector on no 1 or 4 spark plug no problem, without it shorting on the head, but now finding it impossible to get it on 2 or 3, this connector has always been a pain to use, I think its more suited to a distributer cap, anyone know a more reliable connector I could convert it so its sohc friendly? Ah the joys of points ignition, its all coming back!!

must agree,  always think a Honda four is a true "Drivers bike"  its way to functional a motorcycle to be over-restored, nice to see but sadly is becoming some sort of investment piece, and owners are being shafted for the cost of parts. 

I would like that paint job though.
