Here I try to show the difference between the road going bike and track bike.
Sadly I have measured the Track bike with a fixed rpm filter to get a smoother curve turns out that ones measured it can't be set back to rough data.
So it is a bid difficult to compare it one on one but it shows some interesting thinks.
Easy to see the smooth curve is from the track bike the rough curve is from the road going bike.
Here stock ignition setup on the road going bike vs track bike
All close to the 22,3HP mark, but the shortened exhaust gives a nice over rev
Here the 4degrees on the road going bike vs. the 6degrees on the track bike.
Now you can see that the more advange is killing the over rev the shortened pipe is just not holding it.
Road going bike vs latest point track bike
