Anyone that has one of the HotSeat pipes that is adjustable how many spacers do you use and can you notice the difference? I originaly installed mine on my Scrambler 400 4x4 with one spacer and then moved to two after a while. It seemed to not have any top-end anymore but didn't make much difference in low-end or mid-range. I changed the clutch setup and pilot jet at the same time I added the spacer so I'm not sure if it is because of jetting problems or something else? I have not yet gotten the chance to take off the second spacer to see if the mid-range and top-end power comes back.

 

Sorry to say, but TUNING RULE # 1 states:
NEVER MAKE MORE THAN 1 CHANGE AT A TIME.
MAKING MORE THAN 1 CHANGE NOT TELL YOU WHICH CHANGE EITHER IMPROVED OR SLOWED DOWN THE QUAD.
Sorry to be blunt, but that's how you tune an engine to get the best performance.
