I can remember ( only just) back in the late seventies one of our bike club members had duel 40mm webers on his 750 and it always seemed just a little quicker than my F1 version but man did it sound good. The intake roar was amazing. If I wasn't trying to build a fairly faithful cr replica I might have given it a go myself.

Yes. I picked up on it. I have already spoken to electrex regarding one of their systems which is probably the way I will end up going it was just me not wanting to bin a pretty much unused boyer mk3 and coils to replace them with something else. Not only thick about electrics but a bit skint.

Cheers for the advice Phil. Greatly appreciated. I am, as you may have guessed, a bit thick when it comes to electrics so I will give Andy a bell and get his thoughts on the best option.

Thanks for the reply Phil. I know Andy quite well so im aware of the system hes developing to retain the starter which im not going to be doing. You say your using the "race alternator" Does it use a permanent magnet for the rotor or do you still require a battery. And do you know if it can be purchased separately or only as a complete system. Although im pretty handy at most things....ignition systems and electrics in general are not one of them so any help or advice will be greatly appreciated.

Hi guys. still on with my cr750 build and looking for some advice on the ignition system. Currently, the bike still has the standard rotor and stator but I really don't want to have a battery and have no wish to have an electric start or for that matter lights. I already have a boyer 2 and coils fitted so buying a complete new electrex seems a bit overkill and having spoken to them, they don't want to sell me the stator/ rotor only as they tell me it wont work. They supply the same electronic ignition and coils as I have on the bike  Anyone got any suggestions as to fitting a system with a permanent magnet / stator from another Honda. As far as my limited knowledge goes I only need to supply power or im I being a bit thick?

Thank you for the link....I might just go down that route. Being an engineer myself, I can appreciate the work that goes into developing such a thing.

Just new to the forum. I sourced some engine paint from the states which was a two stage system. I will search my records and see if I can find where I got it from and post asap. It was exceptional and had just the right sheen. I used on one of my café build cx500 motors and everyone commented how good it looked.

Me again...already. Have I read somewhere that a popular modification to some racing cb750s is to fit the cb450 black bomber cam chain tensioner unit due to it being a much better design and being more reliable. Its evidently a straight swap but Iv heard that before. If anyone has done this or tried how did it work out, any pitfalls to watch for.

New to the forum so heres my first question for all you experts. As I recall, a 1973 cb750 was fitted as standard with 28mm carbs. When I measure mine there 30.5mm at the head side of the throat. Am I measuring the wrong place or have they been changed or modified. They look standard but I think every other part of the motor has been played with which is making me wonder. Any advice will be greatly appreciated.

Hi guys, just a quick post to say HELLO and introduce myself. The names Mark but most call me Scoot. Getting on a bit now but as an x racer, I still love a quick sweet handling bike so after building and selling many café racers I thought it was time to build one for myself. I had an F1 back in 1976 which I kept for a while, but as I also had a gl1000 it ended up in someone else's garage. I have now found a very nice, although not standard cb750 k3 which I am building as a cr750 replica ( no not another " Dick Mann" rep) but a Jim Redman style one.
On a personal note, I live in the co Durham area, Im 60 going on 18 and according to my wife " I don't snore, I dream im a motorbike"
I am a reasonable mechanic but im a bit out of touch with the cb 750 so please bear with me when I start asking for advice.
