I agree with the above suggestion to reduce the leak jet size. I went to a #35. That and adjusting the AP linkage helped the most I think.
Worth the 80 or 90 $$ Hard to say. I'd rather have put that toward a Vortex CDI. I sometimes ride in verrrrrryyy slippery conditions and hear the traction map works great.

There are 5 things that can be adjusted to affect the bog.
1) the Boysen cover (which reduce the volume of gas in the squirt)
2) the leak jet (which also affects the volume of gas in the squirt)
3) the Accelerator Pump screw (affects the duration of the squirt)
4) the pilot jet.
5) the pilot jet air screw.
If you have the WR450 manual, study the section on tuning your carb. It's good information and will teach you a lot before you waste a $100.

First of all, how would you get air in the fuel circuit?
I thought the Boysen eliminated most of the air associated with the stock Accelerator pump. The stock one injects more air which causes the bog. I could be wrong though. Maybe someone can shed some light.
What the boyesen does is fill up with fuel quicker and deliver a full squirt of fuel.
Accelerator pump only works when you turn the throttle.
I can only see the boyesen of benefit if you are on and off the throttle every second.

Redbeards carb stuff
Either way...I did it to mine today and bye bye bog of the bottom... Basically you just tighten up the AP response.
BTW..remember this is a four stroke so the two-smoke crispy response will never be equaled unless you supercharge that 4 cycle beast. But even still, we're talking about one cylinder that may be on the intake stroke when you want power now...
