Looking to get some more *UMPH* from your VZ800 Marauder? Here's a little air intake modification tutorial to give your bike just the boost it needs. This intake mod took me about 10minutes to do and the improvement to acceleration/idle was hugely noticable!
Tools you'll need:
2)Phillips screw driver (the + one )
3)Razor blade or sharp knife
4)The fleshy grey muscle between your ears... (aka: Brain)
LETS GET CRACK'N!!!
Firstly, remove the chrome cover located directly under your seat. (Should be one allan bolt and then it just pops off)
Next, locate the air-intake (it's a little black rubber guy with a "pig-snout" type opening) and remove the 4 bolts holding the intake and inner-filter in place. Remove the assembly from the bike.
Should look like this:
Loosen the screw on the clamp the holds the rubber intake and the filter base/assembly together. Remove the rubber intake from it's base. Notice inside the rubber intake that 50% of the opening is sealed off. This flap is restricting airflow to your oxygen-hungry engine and thus choking out that little nip of power we all desire from our 800cc's...let us fix that...
Get your razor blade ready and hold it firmly between your index finger and your thumb. Raise the blade to the sky and scream "By the power of Grey Skull!... Give my engine the power!" (He-man quote essential to completion of this project) and carefully cut out that little flap while leaving the center fin in tact. Basically mimic the open hole on the opposit side.
re-attach the whole mess and insert it back into your engine with the rubber nozzle facing the front of the bike to increase air-flow.
Now fire her up and listen to the idle...better? Now take her for a run around the block...better? The answer is "hell yes" to both of those questions and you did it all for 0$ and ten minutes of your time! If you are really feeling saucy, you can trim up the chrome box that encases the assembly with a dremmel or add some holes in the right side of the box to increase flow to the intake while riding...
You can thank me by lighting em' up at 2am and waking up your neighbors ...BWOOOM!!!
