Hi Dan, Well that is a surprise. I was sure it was the valve timing. That would have been a cheap and easy fix. Now what? Carbs?
The 1200's used the same Mikuni carbs thru the model run. The 900's also used the Mikunis up until 1998-1999. Then they went to Keihin carbs. I had Keihin carbs on my 900 Trophy for about a year, too civilized. Even the 900 carb parts swap out with the 1200's, but the linkage is different. I don't understand why the main jets are so much bigger on the 900's. 125's compared to 110's. Probably it's a milder cam. How many miles do you you have on those 1200 carbs? If over 60,000 the needle jet tubes would no longer be round. But it wouldn't be the cause of the lack of revs. I think the problem is coming down to 2 causes. The vacuum slides aren't coming up, or you've got a bad CDI box.
I have two extra 1200 CDI boxes, but they are impossible to get to right now. They are in the shipping boxes that has been sent to Arizona. I'll be leaving California soon.
