Yes.

Sump pan off and you'll see the "tensioning" wheel from underneath just in front of oil pump.

Dave, I seem to get differing results:

Or am I misreading it?

According to the Denso site the plugs you need are Denso-X22ES-U   4. I ordered a set from the Green Spark Plug Company on 24th April and I'm still waiting for them! I have chased them up twice now, the first time the response was they are waiting for Denso to send one plug to complete the order and second time I received no reply at all. Pretty shoddy service really and I wouldn't recommend them.

Thanks Ted,
Didn't know of that company. There is also a W24EP-U but that has a solid SAE connector.

    More and more vehicle manufacturers are dropping or scaling back EV production and going down the Hydrogen route. Even
   Tesla are making a Hydrogen fuel car, or as Elon used to call them not long ago Hydrogen fool cells. Battery only EVs will end up
   the Betamax of the car world. IMHO.

Well, that was a mixed bag. Everything back together and checked the cam chain tensioner, valve clearances and static timing.

The bike started really easily and I thought I had cracked this bike fettling malarkey. Only to find it is firing on the right side only, no heat to speak of all more left exhaust.

Also he bike was idling around 1800rpm and I couldn’t bring it down a lower.

Now to try and find out why!

Does someone know the equivalent Denso plug to replace NGK ones on my 400/4?

I spent hours last weekend chasing a fault only to find it was my complete set of plugs that were faulty. They worked initially on the new engine build and all was good apart from fuel leaks. This led me to believe that the ignition system was OK (How wrong I was!) Carbs sorted and installed and no firing at all. As The carbs had been off I assumed the issue was there.
Anyway, on a whim I replaced the plugs with an old set and the engine purred like a kitten.
I have yet to establish if the plugs are fake but with so many fake ones around, as I have discovered, I thought Denso ones might be an option.

My Son-in-Law runs a firms Ford Mach-E he has had it for about 18 months or so - it does have a decent range 260 or so miles.
If you have to use a public charging point it's as expensive as a Petrol vehicle to run. Home charging with a special EV tariff seems to be the  way forwards.

The difficulty as I see it with a fully  EV is when the battery fails most all electric cars will be worthless, I do know some Merc hybrids are failing in under 10 years with replacement battery units costing close to £10k for a hybrid.

I do like the idea of the optional range extenders on the early small BMW i3 that had the abilty to charge the battery as you were driving. I ended up replacing our 19 year old Jeep G.C .3.0 CRD with a Volvo XC40 MHPV as a compromise for the cheaper VED.

I suspect there is a lot of development work still to come not just in battery construction materials but also in terms of electric motor types e.g. Axial Flux or Radial Flux plus some sort of commonality on what voltage electric motor is used.

IMHO buying an all EV is presently on a par with the original Ford Model T in terms of the development curve.

CB500/550 / Re: Has anyone used these coils?
« Last post by McCabe-Thiele (Ted) on May 27, 2024, 01:58:52 PM »
My black Hendler coils are white coloured at the ends where they are sealed and the terminals fit.
There was a black + sign on the positive side moulded into the white ends.
If your coils have no markings on the body at all then I would guess the red connections are most likely positive.

If the coils are connected the wrong way round the bike will run but the HT spark will be reversed so instead of jumping from the centre spark plug tip to earth the spark path is reversed. Not sure what difference this makes in the long term as I know nowt about that sort of theory. I have read that electron flow is not the way most folk think i.e. +ve to -ve but is the reverse.

Folks here will know about the Electronics side of things.
