[QUOTE="SteveO, post: 156763, member: 3636"] If you find MkII Concentrics offensive, have you considered the Mk 1s? OK they aren't original, but look a bit more "period" than Mk IIs and still retain the good old ticklers. I wasn't prepared to use Wassells, I've had bad experiences with their electrical products and won't use their stuff any more. I went to Surrey Cycles and got a pair of genuine 932s for around £250 (you can pay a bit more for the Premium type). They were jetted perfectly and when fitted the bike fired up first or second kick and ticked over almost from cold (still on magneto). It's a lot cheaper than the £1000 quoted. I don't know what you would be facing with the 289s, but after a rebuild I decided not to use the 276s as (a) they had been in store for a year so would need completely rebuilding and even then would probably leak for ever, (b) I discovered my inlets had been opened up to 32mm and flowed, so the standards leave it well undercarbed.
