Yeah, right...

I did the modification today - method #2... Worked fine after I found a long nose pliers to replace the hose after I blocked it.

Due to heavy rain this afternoon I didn't go for a testride. Maybe tomorrow if the rain stops.

Just one question about this air box mod; have any of you experienced any kind of drawbacks afterwards...?

No drawbacks at all, only happiness and joyful motoring! ........well, I have been sampling a little veno collapso

And not to mentioned tat u need not to pay for anything!!!

Btw do i need to blank off the Flap Actuator after removind the hose?

thks.

No need to blank off the flap actuator for the mod to work, though I did just to ensure moisture didn't get in there and rust it up should there ever be a need to reconnect it again in the future.

Blizzard, do update us after u r done with the test ride in regard of the 'drawbacks' if any...

thks ya!

Took her out for a ride today and the difference is significant! The bike's a lot smoother between 2000 rpm and 4000 rpm and I think that I can hear a tougher sound from the engine as well
The jerkiness is gone at low revs and there's a quicker and more even throttle response from 2000 rpm.

No starting problems, no idle problems, no nothing, really. This seems to be a mod that's working without drawbacks of any kind.

Did method 2 today. I made a grub screw from an M4 bolt to block the pipe before putting it back on. That way I should be able to reverse it out easily to unblock it, should the need arise.

Certainly feels a lot nicer below 4000!

Thanks for the idea.

as long as your modified m4 bolt, don't get sucked along the tube and into the cylinders


i used a brass screw with a very large head and also tie wrapped it in the pipe.

Shouldn't be a problem - there's a nice tight metal tube in the way. Mind you, I didn't actually check how wide it was.....

Where did I put those pliers?

Keep it clean! At least you didn't pic up on amarko5's comment

... a screw with a very large head... .

Back to the mod - not that I was worried, but I just checked, and the inlet pipe (no dodgy connotations I hope) is way too small to (searches for unambiguous word) admit an M4 bolt.

Phew.

I did the mod four years ago without any drawdack since.

You may experience some trouble only if the hose is not well obturated.

Did anybody plug the hose on the other injector body ?
This may give a sort of balance between the two depressions.
I remember my YPVS350 had a large hose between the two intake ducts...

I noticed that. The plug I used previously seemed to pass some air ( ) on occasion resulting in the bike seemingly running with an underpowered C2. After some searching it turned out the CO settings of C2 reset to -128 whenever false air was sucked through the hose.

I now found the perfect plug. With the topic on Givi freebie rubber plugs I remembered I had some lying around somewhere and they are the perfect fit.

I don't understand that........ means that it would always be changing to compensate for some change in the induction system.......hmmmmmm
