Ignition Advancer
 

Just dyno'd yesterday with the new build (100.2/ 75.9) and am looking to increase top end. I think the primary reason I'm low on HP is my jetting (pig rich, 10.0, except for a strange spike to 14 from 5200 to 5400) which is a relatively easy fix (though I'll miss the 3-foot flames on decel), but I wanted to get an advancer to help a little on top. With that kind of torque I would think this thing should be in the 115 - 120 range peak.

Anyone know if I can run the +4 advancer with 11.5:1 pistons on pump gas (93)? I'm sure I could get away with it with some C12, but as a daily bike that's not realistic and I don't want to trial-and-error it. Detonation is ugly. Also, anyone know of colder plugs for the SH?

My info from Factory Pro on this is "No".

In my case my comp ratio is 10:1 and they recommended 2 degrees for my engine. I decided not to bother. By increasing your compression you are achieveing the result that the ignition advance would give anyway, and more.

Save your money in my opinion.

Kinda what I was thinking -thanks!
