Looks like an opportunity. On their website they only list a system for cb500. Presumably no good for a 550 k1 ?

Agree Bryan mine didn’t move so I wondered what the point of the slot is.

Maybe remove the tappets and refit the covers minus o rings to give you another handy place to knock. Or if want replace them ( very cheap ) partially screw them in leaving a lip to drive against taking care to protect the valve cover edge. Haven’t tried this but it might be worth investigating.

If there's response by swapping the leads over (within one oil pack) then analysis of why that could happen may give answer.
There's specific performance in the condenser relating to this (if the original system is in place) with it's ability to fire the mixture.
The opposite ends of the coil have slightly different spark characteristics, with also the condition in cylinder from the live one to the wasted spark one maybe causing a bias to disadvantage the live cylinder on compression and give a shift in performance to that cylinder.
Swapping the leads checks for that, also the insulation of the HT too.
Thanks. the leads on my bike are very stiff. I’ve remade the cap connections but I’m not very happy with them. Definitely thinking of doing the Ash fix. On the other hand it starts well and has no high Rev mis fires which makes me think ignition is ok. I can live with the slight tendency to idle foul and my air screws are out more than 1.5 turns from memory running on shell e5. I’ve improved no 1 cylinder running cool by installing #35 pilot jet and overall the bike runs very well.

Thanks Fellahs those are very interesting and helpful replies. I will start reading up on classic bike etc and could be interested in those tools Ian. Impressive that you have the skills and kit to make them. Nothing happening very soon on this but great to know you guys have got my back 👍

Wanted to try something different to restore after the 550k1 so have got a slightly unloved but running 1986 R80, not the faired touring rt one just the naked lighter bike. My daily rider is 1999 1100 GS and I’ve owned several 1200 GS so I could see the lighter lower R80 as a bike I could enjoy long term. The 800 has a reputation as the smoothest airhead and it does have that feel. Restoration will be next winter but my initial research makes me think self restoration of the gearbox is probably out due to special tools, intricate shimming and a press needed which is slightly disappointing and makes me reflect wistfully on the ease of doing the 550. Anyone here with any experience or thought on a BMW airhead ?

Good progress Dom I like the way your design really gives more emphasis to the engine/ exhaust than the stock bike. Shame about the Daytona ( I have a street triple ) but unless you never ride your bikes or do anything in the garage these minor damage issues seem to be an annoying fact of life for most of us.

Interesting thread. This fouling at idle - is this when the revs drop after running steadily for 20 seconds and can be cleared by revving the throttle to restablish the steady idle? Mine does have that tendency on the denso plugs but also one cylinder which is cooler than the others so I’m guessing that’s the one that fouls.
I have found on many different bikes cars lawnmowers-that iridium plugs give better starting, smoother idle and avoid fouling on two strokes. It seems there isn’t one available for the 550 - why not ?

Well done Mike - very satisfying to overcome such problems

I found the Haynes manual very useful. Has the clearest print of the wiring diagram that I could find including Aladdins cave prints.

I have had such a kit for a couple of year after a recommendation from my car garage mechanic and it has worked well for me. I used it to remove the casing gallery plug under the crankshaft of my 550 which had been completely rounded off by po. The harder you turn the more it bites in - got me out of a couple of scrapes.

Well by not having the card option those show traders lost £100 of sales to me yesterday of which they would have given £1.50 to the bank. As they were loading the gear back into the van wonder which they would have preferred ? Now those sales from me will probably go to some eBay seller who is slowly killing them anyway. Trying to go back to cash is raging at the wind.

I was there yesterday. Absolutely rammed - the post covid thinning out is over. Bought a few tools - amazing that many stands didn’t take cards and there was no cash machine at the showground. Didn’t see a single sohc of note. Looks like this show has got staying power after all.

Time for another little run out. All working great though front brake needs more miles to bed in. This is looking out over morecambe Bay near Cartmel Close to my home. 550 has got a lot of soul and is a very comfortable ride for my rubbish hip joints. [ Guests cannot view attachments ]
