Here is a picture I have never viewed before. Gives more details of left side, with fairing off. Not sure if it is Dick's bike but for sure one of the 4 Daytona 200 1979 RC750's works machines.

Mark @ m3 racing

Hi Mark, what make of front tyre is that in the picture? All the pictures that I have of the factory bikes show them to be shod with Dunlop KRs. (all 4)
Wondering if any of them tried diferent tyres, I asked Tommy Robb and mechanic Steve Murray but neither could confirm if they did or not. At 77 and pushing 80, 8)  both said their memories are not what they were and it was 41 years ago after all. :'( Tommy said he would have been contracted to Dunlop at the time and wouldn't have been able to use any other tyre anyway.
He's going to phone Smithy tomorrow to see if he can remember and get back to me.
I would imagine if it is a Daytona bike, it will probably be Dick Manns as the tyre looks like a Goodyear.

Sam. ;)


There tried Goodyears also, as there is a picture of Mann's bike with a Goodyear on the front and no front fender (mudguard in your country) as it was too wide to fit under fender.

What's wrong with that shift linkage? Thing of beauty in my book.

One would think they would have paid more attention to proper shift linkage geometry!!

The angles are wrong; the levers should be close to parallel.

I think pedal location and certainly, positioning is rider preference, not anything to do with angles and looks.

If you are looking for Bob Jameson's address, or bob Hansen's...I talk to both of them all the time. Bob J does not do internet, so it will be phone calls or writing letters.


Bob H is on net but is 91 so he does not always respond in a timely manner.


Best, if you would contact me, prior to outright honing and I will get you a proper intro.

Hey Jimmy - what's going on a question you didn't ask me first :-)

Should be a standard M14 x 1.5 bolt and it's a common sump drain bolt size if you want to get a honda part from dave silver or CMSNL

Hi Simon/ Jimmy

The Honda sump plug are M12x1.5. The drain plug on the Meadspeed tank is as you said M14x1.5...... Most Yamaha sportbike sump plugs, like R1.

I have billet machined M12x1.5 plugs with Viton O-ring and drilled for lockwire, 19mm hex head. Also have the gallery plug for the 750.

Jimmy I might have a M14x1.5 plug as per my Honda sump plugs, will check over the weekend.

Well I know mine is a mead speed tank (Bartel made) and it's M14 x 1.5. I ordered a standard Honda part to get the bolt but woul dhave to wade through the mountain of receipts to work out which part it was LOL.

Kevin - think you should make nice billet ones for me and Jimmy with lockwire holes. DO you do any OWO1 parts btw?

Jimmy - anytime Matey, always happy to help another CR750 nut with questions - no such thing as a stupid question mind you, only stupid people who are too shy to ask when they really want to :D

Guys, there is a new CR750 kit part DC generator for sale by one of the VRRA members. Listed as kit part for the CR750, CR350, CR72/73, CR93. New, never installed stator & rotor, includes the points cam. He says list price in 1985 from American Honda was $2700, he'll sell for $1000 or vnr offer.

Let me know and I can point you in the right direction.

Lovely stuff Kevin - what do I owe you?
For the owo1 I'm after lots of parts but thought you might do those lovely drilled mushroom fasteners that bolt into the side of the seat. Do you know the ones I mean?

Is it the "970" part number  or "971" as if it is the 970 numbered part it is huge and fits in street bike cover and uses POINTs to fire spark plugs...absolutely worthless on a any race bike. If you want it to look at or install on a classic museum piece, spend the $$$. The "971" part is the smaller one of the two and still utilizes POINTs to fire the spk plugs...again, worthless. I have replica covers if someone has to own this piece of history. System is called  ETI, energy transfer ignition. As the rotor is timed to the stator and the points have to be set to fire coils at exact time as rotor/stator are aligned. Ancient junk. Good luck

I think you summed up the risks of building the perect 970 racer nicely there Mark. It's a nice projec to be able to complete a true 970 racer but would you really WANT to race it? Modern technology and metallurgy has improved so many of those original kit parts that you could be better off, faster, safer and save money by avoiding the 970 parts and buying modern equivalents from the CR750 specialists. Just my £0.02 :D

I don't know Mark, but you may. The parts are offered by Tom Faulds. He was selling some pistons for the "six" as well.
