idle speed

[a101960]

just as a matter of interest, what is the correct idle/tickover speed for an A10? I have mine set at 1000 rpm when at normal running temperature. Is that about right?

Recently getting my super rocket going, I certainly found 1000rpm a good solid benchmark, the owners handbook mentions the best setting may vary slightly to suit riders requirements or particular localities.
Certainly unlike a beesa preunit single which will happily idle at close to no rpm a twin needs some idle engine speed to keep oil pressure to its mains, so don't be tempted to drop it down too far just because you can!

I agree, don't try to make it sound like an 8 stroking HD. Both mine are happy at 900-950.

All HD 's sound like that to me !!

I was just reading that the "new" norton twins idle at 1300rpm!  so 900-1000 can't be far off.

First of all, thank you all for your comments. The reason I asked about the idle speed is because 1000 rpm sometimes seems a bit slow. I was not aware of the possible lack of lubrication at slow idle speeds, so that is useful to know. What I was concerned about was the possibility of the engine cutting out while idling. I do have a good steady reliable idle, but you never know! There is no direct comparison comparison but a few years ago I had a Mini that was fitted with an Oselli 1400 engine and the recomended idle speed ( by Oselli) was 1300 rpm. Those of you that are familiar with Minis will be aware that the Oselli  was pretty trick engine. I think that the specification of the engine that I had was drawn up by Clive Trickey (a well known Mini go faster guru). What I can say is that it was certainly quick. If any attempt was made to reduce the idle speed it ran very lumpily. All to do with the cam form, timing, and big carburettors so I was told. Nothing like an A10. I just do not want the engine stalling when I am the head of the que at a set off traffic lights. You all know what a faff that is, and it is the one time in my experience when the engine is guaranteed not to re-start easily or quickly.

 I think the Haynes rule of thumb, maybe for the Gutzzi, is remove one plug lead and set the idle so the other side doesn't stall, and then repeat for the other side( and hope it's the same) adjust up if necessary.
 Having said that, some say it's not advisable to run a maggie with HT lead disconnected.

 When my Plunger GF/R is at idle, with the high flow cast iron oil pump there's still a decent steady flow of oil returning.

 If stuck at standstill for too long, just give it a brief-slow squirt occasionally

Mine too; got the same pump*.

* Not meaning we are sharing an oil pump. That would be very awkward!
