Hi Don, Just an aside but uh-uh:- . all current Boyer-Bransden e.i. certainly for Triumph twins with points-in-timing-cover, full advance is 4,000 rpm. (Mk.4, MicroDigital, MicroPower, all instruction no. 23); . although the Mk.4 destructions say they're also for the Mk.3, the ones that came...

Hi Ed, Halfpint, Tch ... the see-saw emoticon in the old software would've illustrated my dilemma perfectly ... should I post or should I keep my gob shut ...? On the old software, I was just a mod. on CVV ("section mod"?); however, the new software has promoted me ... I'm now a mod. on every...

Hi Gerrit, Firstly, thanks for taking the time to respond both here and on CVV. (y) Fwiw, I'm also in GB, same as "Caulky" but I didn't see any of the stuff he complained about? Hth. Regards,

Hi Rory, If the speedo. is a genuine Smiths, the trip reset knob pulls out of the speedo.; you'd be wise to do this before attempting to remove the speedo. itself from the rubber (it is rubber :)) moulding, especially as the speedo. is then more likely to simply push out of the moulding. Otoh...

Hi, I've moved this to the main CVV Forum, where more people will read it. Hth. Regards,

Hi Jeff, Marc, Easier than that - there are several makers of 'dry frame'-lookalike plastic covers specifically to fit OIF - iirc, they use the OIF sidepanels attachment to the airbox? Otoh, actual 'dry frame' sidepanel and oil tank will require mounting brackets brazing to the frame. Hth...

Hi Jonner, I've moved this to the main CVV Forum where more people'll read it. Regards,

Hi K, Don't forget the ring-binder format of '63-on workshop manuals allowed Meriden to supply dealers with supplements just detailing any changes in a given year; e.g. my C-range manual only has the supplements up to '69, the latest wiring diagrams, say, are captioned "from H65573"; otoh, the...

Hi Andy, Mmmm ... given the additional information about the sidepanels and airbox your bike has already, the attraction of the opportunity is understandable, hope it works out. (y) So was that a thread of yours I was remembering? Regards,

Hi Dave, Peg, Uh-uh; the modern equivalent of WM2 is 1.85 (inches); similarly, WM3 is 2.15 (inches); otoh, 2.50 (inches) is WM4 equivalent but 3.5 inches is wider than the widest WM - WM5 was 3 inches. Aside, uh-uh again; as you can see above, there aren't any "half sizes" apart from the one...

Hi, Mmmm ... ime, those particular horns are nothing like as heavy as the two earlier twin-horn types. However, all three types were mounted differently on the triples - each horn separately on its own bracket off the frame tube behind either the oil tank or sidepanel, relay on a plate under...

Hi Andy, What about sidepanels and airbox, because the seat is (frame seat rails are) lower? IIrc, there was a thread a while ago where carbs. and air filter connections didn't match up because of something similar? Phrase after the "-" will be the more-significant one when/if you come to sell...

Hi, Same diagram should be in the twins' workshop manuals; it's in the 350/500 manual but the whole '69/'70 addendum section is missing from the classicbike.biz '63-'70 650 manual ... Note they all have a misprint showing the horns relay with a "red" wire from the relay to an 'earth'/'ground'...

Hi Jeff, Firstly, welcome to the Forum. :) Any reason why? One of the original reasons for the OIF and the removal of the separate oil tank was the space freed behind the carb(s). allowed for a much larger airbox, which was already known to reduce overall noise and provide a basis for other...

Hi Greg, Any idea why the fuses didn't blow on the bikes you've had to rewire? Hth. Regards.

Strange post ... :confused:

Hi Tony, About 13~14K; adjusters are about half-way along. I bought the bike (a '77 Honda CB750A) in early 1992 initially because I was doing a 70-mile round-trip commute five days a week mainly on dual carriageways and the bike was fitted with a Vetter fairing. The chain it came with shagged...

Hi Nigel, Thanks for your confidence. :) Some thoughts:- . Your diagram shows Red wires connecting Pod, Boyer-Bransden Transistor Box and coil series to battery +ve, but other components' +ve connections to 'earth' symbols; is that just for clarity or are you planning to connect those other...

Hi Greg, :D They are. The only reason I posted, "Strictly-speaking, BSC " is I was ticked-off :rolleyes: recently on BritBike for copying an OP's use of "SAE" when referring to Unified threads - strictly-speaking, :) "UTS". In a similar way, the Cycle Engineers Institute was so-named only...

Hi Tony, :nod Know a couple of guys who sand-race - chains donald every meeting ... Not found it with Scottoilers once they're set up, just a bit fiddly to set up and each one, or the bike, is an individual. :bluduh But, approaching twenty-eight years from one chain is worth a bit of time...
