Fully agree with staying on the conservative side of rev limit / ignition timing, especially since I have over a year on my factory warranty. 8500 would also be my limit, unless someone starts offering higher pressure valve springs to complement. My primary interest was more with squeezing a coupla more degrees of timing advance to give the ignition a slightly more aggressive burn, BUT within the realm of keeping my Speedmaster as the non-detonating, 89 Octane burning, riding 100 miles-a-week special. My Speedmaster already has Stage 1 cams, CRS 35mm carbs, reverse megaphone exhaust, K&N Air filters, and AI removed, now just want to concentrate on subtle things (ie timing, billet intake manifolds, iridium spark plugs) to give me more performance without having to fork out close to $1G to buy and have installed, a big bore kit, plus spend another $1G to have the head sent off for port and polishing. On the other hand (evil) raising my RPM limit would give me the flexibility to go up a tooth or two on my rear sprocket and give my bike a little more grunt, without loosing top end speed (so evil)

What are the thoughts??

BTW, thanks to the Gent that posted the link for the European guy up yonder :-)
