HOW MUCH POWER

[stroking]

WHAT is this doing for my power output ?

more topend/bottom/everywhere???

 

putting the spacer behind the reeds

I'm no expert but IMO, spacers are only made for clearing bigger carbs. Too me it sounds like more possible air leaks as well.

Have you looked at the reeds? Don't know who's reeds they are but the reed cage may need the clearance, longer reeds will give you more edge length and therefore air flow. If the reed cages fit in the port without any obstructions then there's no reason for the spacers that I can think of.

I have seen people argue this issue alot,in banshee world we use them to clear bigger carbs or just put them there because we have them.I dont think you will see any increase.In theory it should make the intake runner longer for better atomizing

IMO.... unless you have clearance issues, (ie: BIG Carbs/Bowls) I dont think the air leak risk would be worth the small power increase you might see.....

waht he said... lol

I remember someone did a couple of dyno runs with and without the spacer and he posted there was actually a decrease in power with the spacers. It was less than 2HP but it was still a loss....

They are supposed to be used to clear the float bowl from the clutch arm. If you don't need them, you might wanna get rid of them because as was posted, the potential for a vacuum leak isn't worth the loss of performance!!

There is science behind it with intake tract length in conjunction with the motor and exhaust.

In reality...on a banshee, use the spacers for clearance.

 

if you were a super bike rider and spent every second in the upper RPMs of the motor and needed every last .5 HP...you could play with the spacer thickness to tune in the motor.

 

I could effectively add crankcase volume...and could be useful if tuned properly.

 

However...in the real world for an everyday banshee owner, bend the lever down, grind off some of the drain plug or put the spacer after the reeds.
