Def talk to de3, he should be able to assist for sure. He will respond back some time today. Probably this morning...
Can you hear it sucking the air through the intake. Cause you shouldn't. Take a piece of duct tape and cover half the hole on the snorkel.
Does it get a little better or little worse? Gets worse you need more air. Gets better needs more fuel. Your main you installed is it bigger or smaller than the one you just replaced.
My Personal opinion is your main jet may be to large. Now that you have added the silencer, being its falling on its face at the bottom. I had the same issues with my 300 Honda during my build up process on it. Main jet was to big. And it was dumping to much fuel in to early. And after it gets to the top it ran pretty good but not tip top. I leaned it out but running a smaller main jet and its a 300 class champ now! Plus just because you added a snorkel doesn't mean you need to change the jets.
The more air that can make it to the throttle body the better. The throttle body then adjusts the amount of air to fuel mixture not your intake inlet. Unless its fuel injected then you may have problems.
Some fuel injected models air boxes double as not only the air box it's self but a blatter for a specific volume of air. And when that volume is changed it may have adverse effects on the performance.
Think of a gun (your engine) and the bullet (your exhaust gas) The noise is not only an explosion but the compression of the bullet against the air. A silencer obsorbs all of the noise and the compression of that bullet. This causes the velocity of the bullet to slow down drastically reducing noise.
And that's what your silencer is doing to your buggy.
Larger intake - no change
High altitudes - run richer (less air)
Silencer air restriction - run richer (more air restriction)
Larger jet - run richer (more fuel)
I hope this can help.
