I installed boysen power reeds in my 01 srx 700. I'm only getting 8150rpms on hardpack/ice wide open. Could the reeds be causing this? Sled runs awesome but doesn't have the pop that it did.
 
Okay, I'm running 4.5 inner and 4.5 tip, have a yellow white yellow primary spring, 51/43 helix with green secondary spring
 
also unless things have changed most people will tell you to stick with the stock Yamaha reeds
 
Don't the power reeds have a bottom and a top? Have you got them in correctly?

It's wrapped at 70 I believe. And the reeds are installed correctly. I had read before I purchased this brand that some had issues with pulling rpms...idk.
 
A couple of bucks said:
If you have to remove tip weight with the new reeds, that's telling me your making less power.

I have read that they change jetting which makes sense since they are supposed to increase flow, I guess. Could it be its not at a optimal air fuel ratio therefore it's not making full use of the potential and if jetted for the reeds he would then pull the weight? I am just throwing out a theory, I'm interested in this topic. I have read don't get them unless, okay I have slp triples mrviper trail ported heelclicker setup, would this qualify for the above mentioned "unless" requirement?
 
The cost is so low I would go to your local dealer as they will have them in 2-3 days.
