850 low RPM

Some good news. I put in a #45 pilot and it helped by about 50%. The air screw has run out of room, however. A few test rides will tell the tale.

I've had the same "Shudder" also as long as I've owned my '75 850, (twin Amal's) but I always considered it a characteristic rather than an annoyance.

I'm beginning to think it is a characteristic, a brief shake point around 2000 - 2500

Commando 850 does shake until 2500-3100 rpm depending a lot on condition of and setting of the Isolastics. Should smooth out above that range.
