Progress

[Spitfire]

Well by dodging the rain and family commitments I've put about 120 miles on the F1, still some teething troubles to sort out and some sorted already:
1. Left fork seal leaking, stripped and new seal and fork tube fitted.
2. Front brake MC overhauled again after accidently refilling it with fork oil, discovered this when I could not find the fork oil after job 1. just this big brown bottle of brake fluid (stupid boy) all brake lines flushed out. Will change out the caliper seal tomorrow.
3. Tacho drive seal changed, it's leaked for years and it's time was up !
4. Carbs synched but tickover still rough, suspect the pilot jet passages are semi plugged, overhauling a spare set of carbs just in case.
5. No.4 plug sooting up, plugs changed out but discovered they are the wrong plugs, DR8ES-L instead of D8EA, the R stands for resistor, thought the spark was a bit yellow/orange. The resistor is fitted so that it doesn't interfere with the bikes ECU or CDI ignition !
Will test ride tomorrow to see if this works, if not will check the float level (again), No3 is a bit sooty as well but not as bad as No. 4.
The other likely cause could be my too quiet BSM silencer, maybe a few holes might appear in it.
6. Ignition timing, had one hell of a job getting 2&3 lined up, looking closer the post on the points was bent, so they were replaced and all is well. The entire points plate was replaced during the rebuild, so I may have caught it with a spanner when I was turing the engine over.
Still to be addressed, front brake squeel, tickover, sticky (dragging) clutch and dodgy rider.

Den, sack the points and put some electronc ignition on the bike....3 sets of ND point and it's paid for it's self! Set once and forget, I got the Dyna system from the US and it's not like the old 70/80's stuff it all fits behind the chrome cover.

Glad to hear your getting some miles on your bike Den  , and ironing out the teething problems, i have to check the fuel tap or the float levels on my 750 KO thingy after its been sood it starts dribbling from a couple of the overflow tubes  , cheers mick.

The only thing that stops me fitting a Dyna is the initial set up, I'm an old fashioned points man and the thought of setting it up puts me off.

Cheers

Den, if you can gap and set up timing on a point

[Asimohonda]

  Hi Den I fitted electronic ignition to my F1 it is the
best thing I ever did the K2 is getting the same treatment
Points systems are old hat electronic ignition fit & forget.
Hey Biffta is that bike of yours in the front room? My musses
would kill me for pulling that trick. Dyna Coils fit straght onto a CB750

[dave400]

Asi, yes my bike was in the living room, but its now finished and in the garage.

[Spitfire]

OK I'll have to check this one out then, I have new Honda coils but will look at the Dyna.

Cheers

Den

[dave400]

Den, you don

[Asimohonda]

  Same here Den 30 year old coils not a good idea
 but as yours are new why bother

[mick]

Did you get your electronic ignition from Z1 Dave, i'm still running points & condensers on my F1  but i might just treat myself ,   cheers mick.

[dave400]

Yes Mick, and I got my parts within a week, the guy is a Brit and a nice bloke to deal with.

Had points on my replica's and they were running well. On the Japauto replica
bought a used Boyer & Bransden unit and put it on and made a big difference in starting and pick up from low revs, but the biggest advantage was that on high(er) revs there still were sparks, it keeps running!

For the other bike I have a Dyna ignition and coils.

Voxy, with all the rain we get in the UK, I would never fit the Boyer ignition unit because I don

[Voxonda]

Hey biffta,

Think the weather overhere is not all that better. Agree, had my reservations against the 'box' but it looks well sealed and if you put it on a well protected place it should do fine. Besides this I am running these bikes 'on track' and in fine weather (I hope).

Cheers, Rob
