Just over 2 weeks to go.  I am getting my Honda 250 ready.  Not much changed over the winter.  Rebuilt the water pump which blew a seal.  I have placed a velocity stack on the carb rather than a restrictive air filter.  I also improved the efficiency of the nitrous bottle heater so I could use it on a cool morning if needed.  Not sure I will run NOS in April.  Now off to the dyno next tuesday to rejet for the improved intake flow.  Of course I'm also curious what the RWHP is now since the last time on the dyno was May 2009.  I may test the nitrous on the dyno as well.  Sorry but the Honda will not be any quieter in April.  It seems to like the straight pipe length for resonance.  I did put my bike number on the front of the fairing to make it easier for the starter to call it in to the tower.
My 1954 Moto Parilla 175 is stripped apart on the workbench with many upgrades planned for May meet.  See everyone soon.
