rhb Posted November 13, 2016 Share Posted November 13, 2016 Has anyone here modded this type of snorkel by either using an aftermarket DNA filter and cover, hordbox, or simply hacked away and deactivated the flapper, along with aftermarket filter? Interested in performance gains vs. practicality etc. From what I've read simply changing the filter/snorkle has little benefit. this would be combined with a leovince and ECU flash eventually.

pattonme Posted November 13, 2016 Share Posted November 13, 2016 @2wheeler can probably shed some light on this as well. I believe the immediately useful mod is to chop the large diameter, smooth round tube shorter by say an inch. Link to comment Share on other sites More sharing options...
Premium Member rowdy Posted November 13, 2016 Premium Member Share Posted November 13, 2016 I swapped mine for the DNA with an MWR filter and attempted to install a Power Commander V. The PCV had a problem in the wiring harness and I had to remove it and send it back. I tried to run the bike without it, but it ran like utter crap. Now I'm back to stock. I think any meaningful changes to the air box will probably require fuel management of some type to make a positive difference. Why can't left turners see us?

Thanks, I do plan an ECU flash, Link to comment Share on other sites More sharing options...
rhb Posted November 13, 2016 Author Share Posted November 13, 2016 Also read where some are disconnecting/plugging the vacuum line and gluing the flap down. Link to comment Share on other sites More sharing options...
Guest 2wheeler Posted November 13, 2016 Share Posted November 13, 2016 Wow, there is quite a difference between the FZ and the MT air box. What I did was completely remove the portion of the snorkel extending into the airbox. Then added a MWR air filter. This was combined with a flash setup for stock exhaust and no snorkel at all. Idea being that the increased air flow of the MWR would offset the reduced air flow created by having the outer snorkel s installed, especially considering the flash was for having no snorkel.

patrolus Posted November 13, 2016 Share Posted November 13, 2016 Is that a restricted version of the mt? - I haven't got that vacuum line nor the thing it attaches to on mine.... as for that snorkel, i just took it off and chucked it out. I did that at the same time as i installed my open acra exhaust, and it created a shitload of popping from running lean, so i got a powercommander to take care of the fuelling. runs sweet now.

Guys are disconectiing the line, plugging it, and gluing the flap down for starters. I was just wondering if any others had tackled this. I'[m going to pull it off and see what I can do to make my own DNA style cover, perhaps molding one from resin or epoxy glass, Can't see buying a DNA plastic cover for 100 bucks.

patrolus Posted November 15, 2016 Share Posted November 15, 2016 Oh I see.....Yeah all that noise from the intake side of the engine....all those regs are just a pain in the back end. I too was looking at the DNA plastic cover to hold the airfilter in place...seems a little over the top to charge that much for a 20 cent plastic ring.... I ended up reusing the original and just got rid of the snorkel.. a few guys on other forums just cut the hole in the original part bigger and some others just used some plywood to make one up-- cheap and easy to work with....... Has the DNA part anything on it to divert rain water? - I read in some other forum that the snorkel is only there to stop water from getting into the airbox in torrential rain situations.....(Hence i won't need mine here in Perth....)
