Trigger Wheel Advance Problems?
Shockbushing Gary:
The advance in a Valk is not constant. The trigger wheel sets where the timing begins, but not the timing curve. That is set in the ICM.
I used a 6 degree wheel in my I/S from 2000 on. It topped out at 125 MPH. That is a direct measure of HP. If it was lacking, it sure wasn't much.
There is a definite bump in response thru the mid-range with the 6 degree wheel. I liked mine. You can buy one, or if you look around here a bit, you'll see how to modify yours to be a 6 degree wheel.

Larry,, I have the same trigger wheel installed and I had a flat spot around 3500 rpm,, but mine was because of the cobra 6 into 6 pipes and I had to put in a needle kit and now have great response and no flat spots at all. I run regular gas and its fine. Went 7000 miles in one trip last summer and got around 30 mpg
Indianawizzar...you should be getting better than 30mpg unless you're running better than 85-90 all the time. I have a 4 deg. wheel with the I/S ICM and running on the super slabs I'll get in the mid 30's easy. On the side roads where the speeds are more moderate, 60-65, I'll get 40-41 mpg.
John,, I was pulling my trailer and going through mountains. This was my average on a 7000 mile trip. I did not think it was too bad

Are you saying, because the wheel starts the timing farther along that the normal flat spot in the response is also shifted ahead a bit too and as a result it is not felt the same in the throttle response? Or am I not understanding this correctly. If not perhaps you could clarify. TIA :) I was only going to put a 4 deg on as that is what I understood in past postings I've read would likely work the best and not advance the timing too much. I usually burn premium anyway because around here, it's cleaner.
MP:
IS should only run a 4. The IS is already a little more advanced than the std. A 4 in the IS gives about the same advance as a 6 in the std.

I have a dyna 3000, and my bike runs sweet. It has more power though out the rpm range.
