I had a simular problem with mine. As you can see, there is the one 
adjustment bolt on the front that you can turn. I placed the vavle in the fridge 
for about an hour, and then turned it to close the vavle, but not even 
completely. I found that after warming up, the valve flap was still only opening 
up half way.

My solution: I totally dumped the the vavle and heat stove. It was also about 
this time that I noticed that the intake diameter of the inlet on the air box is far 
larger than that on the intake vent. I now have the intake hose pulling in air 
from below the rocker cover, inside the engine comparment, but pointed away 
from the radiator. I can tell you that this has allowed the engine to breath 
MUCH easier, and it sounds a bit better.

There are also a couple of things to consider about removing the valve. You 
can connect the fresh air intake hose directly to the intake, but this is not good 
in cold weather. I've noticed that the engine was way too sluggish, and 
noticed a bit of oil consumption. Allowing the intake hose to pull air from 
inside the engine compartment removed these problems, as the engine 
compartment warms up very quickly. Plus performance isn't really sacrificed 
like it would be on other cars. The engine cover is vented, nor is the radiator 
in the same compartment, so the air doesn't get that hot. However, it is a 
problem in the rain. You hit water, and the compartment will steam up. 
Sucking steam into an engine is not something that I'm too happy about, but if 
you never allow water to hit the motor when it's hot, then I wouldn't worry too 
much about it.
