Pazon Altair

I have read the reviews and am pretty keen to get one. I have a mk111 boyer now. I would like ask if the dip in the advance curve at idle would cure the following. On my 850 she shakes really bad between off idle (1200 rpm) and 2000 rpm before the isolastics smooth out the vibes. If the idle is playing up and idling a little to high, say just over 1000 rpm, the engine seems flighty and wants to fly right into the 1200 and above vibration zone. Set the idle back down to 800 rpm & sometimes she will stall.
So will the Altair control the engine better so it hangs around 900~1000 rpm, without the engine wanting to race off to 1200 rpm?

Just keen to know if this will aid this?

Oh, what coils should be used, are traditional style coils okay, I was going to renew theses with items from Pazon as well.

Cheers Richard

Hi Richard
I doubt that changing the electronic ignition will affect this. My logic is that there are lots of Boyers out there of all versions that give a perfectly good idle, as long as the carbs are set right. I suspect you have a carb set up issue, have you been through all the set up and adjustments?

I pretty much agree with pdl999 to look for a carb problem especially air leak -- maybe the rubber balance tube or bolt tightness on the carbs (not too tight but not loose.) I just switched from a Boyer Mk3 to the Altair but have not had a chance to time it dynamically or ride it yet. Only ran it enough to determine that I'd installed it OK. My idle with the Boyer was pretty consistent over 35 years.

The Altair might improve it but may just mask this problem instead of really fixing anything.

Okay,thanks guys. Guess it is back to the drawing board? I have been throught the carburettion pretty extensively. But on reflection when the bike was on points it did not seem to have the same characteristic of wanting to jump revs above 1000rpm or so. And I rode a mates 750 stillon points and it was so much more well behaved in this area? Still may just get the Pazon,fathers day comming up and all!

Anyone want a good boyer set up?

Cheers Richard
