Yoshimura RS3 slip on (Zyclone )

[fcbandit]

I own a 2004 Bandit (Canadian Edition). I have done some extensive experimentation with my bike and the best setting with a Yoshimura RS3 with a Zyclone baffle are:



 With the snorkel on:  main Jet: 102.5                      
        Needle: Stock with a shim of: .064mm
        Pilot screw: 3 ½ turns


Without the snorkel:  Main jet: 107.5
        Needle: Stock with a shim of: .05 mm  
        Pilot screw: 3 ½ turns

The difference between the snorkel on or removed it is the top end performance. With the snorkel on your bike will pull hard up to 8,000 rpm. Without the snorkel it will pull harder up to 9,500 rpm.  


I have tried Ivan’s jet kit with both configurations:

   Holes in the air box has recommended and snorkel removed
  Main jet 112.5
   Ivan’s needles, third clips    
  Pilot screw 3 ½  and 4 turns
   Yoshimura RS3 Zyclone
 

 It was slower than a stock bike

   It was running to rich in hot weather and to lean in cold weather
I have noticed if do some extensive modification in your air box, your bike will be more sensitive the temperature changes.

Only snorkel removed  
  Main jet 100
  Ivan’s needles, third clips
   Pilot screw 3 ½  and 4 turns
   Yoshimura RS3 Zyclone
 
  It was slower than a stock bike, it was running lean

I really tend to disagree with your findings with Ivan's jet kit. You said that after the install the bike was slower than stock.  

I just installed a micron slipon and Ivan's kit, and the difference between my bike now and stock is night and day. Now the bike just flat out hauls booty. Before 1st gear wheelies took some work, now I just wack the throttle and I am vertical. and the power is increased all the way through the full range.  Is it possible that you might have not installed the kit properly or mabye missed something? I think that most of the list members would tend to agree with me from what I have read on the Forums there is no way that your bike should have been slower than stock with a slip on and Ivan's kit.
