Vacuum rubber bits on the 1150 - beware !

[guitarman]

I guess a lot of you guys already know this but I didn't, so if there's anybody as ignorant as me out there it might help

Underneath each, of what I think of as "the carbs" (but are really injector bodies or something - someone will correct me), is a rubber thingymyjig that covers what looks a little like a bleed nipple.

These are, so I was told today, covers for a vacuum inlet pipe (used when balancing the "carbs") and if they start to "deteriorate" (as mine are doing - rather large split in one and signs of deterioration in the other) they will let more air into the cylinders than is healthy causing all sorts of problems with backfires and poor running.

They cost 69p each.

Check 'em.

Sorry if any grandmothers out there are choking on their eggs

Cheers

I read somewhere that if you connect them together with a bit of tube, you get another couple of mousepower. I tried it, never noticed any difference.

There might be a few of us on this board who wouldn't be here if it wasn't for split rubbers

No gain in any sort of fleapower ... just slightly smoother low down idle and synch.
