what exactly does the snorkel do for a quad, and why do u have to remove it to gain preformence after adding an hmf pipe[img]i/expressions/face-icon-small-blush.gif[/img]

dont want to sound stupid, but i want to know this stuff

and anyone who ordered the hmf pipe, what jetting did u run. i ordered a 170 main and that was it.

 

i still have mine with hmf slip on i just have 2 2 inch holes in lid...

 

i have stock filter to 165, main jet which is a dino jet. air screw out 3 turns.

 

Snork restricts airflow, more cleaning tho

 

I picked up a K&N filter for mine and the guy at Alba recommended that I remove the lid and snorkel and use a 165 main and 3 turns on the air screw. Its for better air flow and less restrictive like FsT4WrD said.

 

FsT4WrD what do u mean by more cleaning???

 

Have to clean the air filter every couple of rides

 

thanks for clearing that up with me[img]i/expressions/face-icon-small-cool.gif[/img]

and if i remove the snorkel and dont like it not there, is it a pain in the a$$ to replace it.

 

The snorkel just pulls off, and is easily put back in. It's held in with a rubber grommet. All the snorkel is really for is so that if you get yourself in water that's kinda high....it still gives a path for air through your airbox. Other than that....it's really useless. It does restrict some airflow....because of the foam around the tip, so you will gain a little more air.

If you still have the stock filter, I'd highly recommend getting a high flow filter as a replacement. It's almost pointless to buy a pipe (slip-on or full) and not get the filter. Unless, of course, you just want your Z400 to sound better. The stock filter is very restrictive in comparison to either a K&N or Twin Air or UNI.

 

You don't have to remove the whole snorkle, just the end cap that is held in place by two tabs. I left the tube on cuz the ears with the hole was perfect to hold that vent hose that was previously held by the end cap.
