Have you tried upgrading the single disc? It's cheaper...
I use EBC Pro-Lite rotors and sintered HH brake pads. I can lock the front wheel at 70 mph with 2 fingers on the lever.
Really, braking force is limited to how much traction the front tire has. If you can lock the front tire, that's all the braking you can use. The advantage 2 dual rotors is resisting fade. If you were doing several stops from high speed in a row the single rotor/caliper would heat-fade quickly.
I don't do repeated stops from high speed, so I never heat-faded the brakes on the ol' KP.
Ive gone to Lyndalls pads they're far better than the stock wooden ones.
Ive never faded the single disc yet.
Twin discs look better too...more balanced.
Been keeping a look out for a Hammer S write off that's been hit up the backside but nothings come up yet.
Kingpins full valanced fender looks pretty cool though and would keep the dirt off the front of my bike better.
My Vegas front all the crappy OEM clear is lifting and the fork legs pitted, shitty clears lifting on the triple trees so soon be looking at removing the front end for a total revamp, strip the clear and polish the alloy.
Replace the steering head bearings with tapered rollers too while I'm at it.
Oh yeah booked in for a proper tune to get those A/F's pulled into line, Fred from Procycle agrees with You and Kevinx on how messy the fuelling is, and "will never make good top end power running that rich"
Aug 2nd is the day, at lunchtime, will be ready then for a run on the local strip then I got a day before Ill ride 7 hours north to race proper.
Hopefully it'll all come together that weekend and all the trials and tribulation, waiting, heartaches and bullshit will be behind me...was gonna run Wed night at the local but I don't think I can go any quicker on that tune.
Would like to try some clutchless runs on the strip though, what changes smooth on the street should change equally well at 6K on the track?
After midnight here, Ill read your answer in the morning,.
