I have a before and after run on the same Dyno, at the time bike was fitted with Quill T3 and Ivans slip on kit. IIRC The 4 degree ignition advancer made between 1 and 4 bhp extra up to 9,000rpm after that it was the same. Most of the gain was between 3,500 and 6,000 rpm, as mentioned easier starting, smoother driving and much nicer two up.
I am home next week I will try to find the Dyno run print out and post it here.
IIRC my figure were.
Stock bike (USA import) with 990 miles, 123.5 bhp
Quill T3 and Ivans slip on kit, fitted by Mike, 129 but with bigger gains in mid range (about a week after first run)
as above but with 4 degree ignition advancer gained extra 4 bhp between 5-6,000 rpm same 129 bhp (same day as above)
Akrapovic Ti race can with ivans MB kit (again fitted by Mike) 136 bhp with gains everywhere and a very smooth power curve. fitted @5,500 miles. (about two years after first run)
All Dyno runs carried out at Millenium Motorcycles (power runs only, no mods) in St Helens.
I have also had Dyno runs carried out at Hammer and Tongs in Warrington and J33 near Lancaster which varied by 4 or 5 bhp from those above.
