They make a spray that will help seal the pipe wrap so it does not absorb as much moisture and salt.  Also it helps stop it from fraying.

The wind on the pipe while racing is quite strong and it can cool the pipe down some.  The exhaust gas is cooler and the speed of sound within it changes.  This alters the optimum rpm when the exhaust tuning works best.

This was a problem I had this year.  In the past the pipes were tucked in behind the fairing and out of the main air flow.  The environment they were in during the race was similar to the one at the dyno where they were tuned.  A mild breeze across the pipes, at best.  The power curve recorded on the dyno matched what happened on the flats.

Last year the fairing design was changed and the headers were out in the hurricane force wind when I raced.  The power curve observed while riding was much different than it was on the dyno.  The peak power rpm was about 1000 rpm lower that what was expected.  The bike acted like it had longer pipes than it had on the dyno.

Some math showed me that cooling the pipes and the exhaust gas one to two hundred degrees altered their tuned lengths.  They acted like longer pipes.  The headers will be wrapped this year to keep them warm so the tuned length on the salt resembles their tuned length when we did the dyno work.

Little more progress, engine in, headers mounted, spare wheels on (good wheels have been lightened,have no brake rotor mounts and are a metallic bronze)






Body work test fitted....




If I don't go for a ride I will have them mounted properly tomorrow.

The fairings are going dark metallic blue. grin

Never mind the bike, I'm digging the palm trees and the sailboats in the neighbor's yard!

Did you borrow those fork stanchions from one of Dad's old choppers, or are they really pulled up thru the triple clamps that far?  Will they interfere with getting your head down?  If you shorten them and shorten the springs, they will get stiffer, which might be a good thing.

The front forks are the original forks  smiley. They will be getting cut down once we work out what height the bike is running etc.


The cat and palm tree's are both dads tho.

Nice work Dave - sorta has a Tron Light-cycle look to it.

Did you add gussets where you extended the swing arm? The one photo of the weld made it look a bit suss...

Just curious - - why did you cut out the rear fairing to expose the wheels?
