I thought it might be helpful to have step-by-step instructions for this since it seems that there has been some confusion between Gen I and II and people have been blocking off the wrong hoses.
The purpose of this mod is to alleviate the popping on deceleration (afterfiring) after installing a full, aftermarket exhaust system. I'm not interested in doing the entire pair valve block off mod, so the suggested method has been to use a marble to block this hose. At first I was leery of using a marble and bought several different sizes of plugs from the hardware store, but in the end, the marble fit the best and seemed the most apt to stay put. I added an extra step/mod in the form of a zip-tie after the clip and marble in an attempt to keep it lodged there.
Here goes...
Step 1:
Remove both (2) tank bolts.
Step 2:
Remove both (2) seat bolts.
Step 3:
Lift and prop the fuel tank. (Easier when you're closer to Empty than Full)
Step 4:
Go to the RIGHT | THROTTLE-SIDE | BRAKE-SIDE of the bike. Look underneath the airbox and locate the airbox breathing tube towards the front | stem of the bike.
Step 5:
Detach the breather hose from the airbox. Keep an eye on or even temporarily remove the clip to prevent it from sliding back down the hose.
Step 6: (Before inserting the marble)
For those that are paranoid about the marble getting sucked back into the intake, I've added a zip-tie further down the hose, just tight enough to keep the marble from going back down the hose.
Step 7:
Insert the marble into the breather hose. As you'll see, the marble fits pretty snug.
Step 8:
Put the clip back on the hose and re-attach it back to the airbox. Make sure that the hose is slid all the way up the nipple and that clip is secure around the nipple, not the marble.
Step 9:
Snip the zip-tie end (if you used one), lower the tank, re-apply both (2) tank bolts.
Step 10:
Re-attach the seat and seat bolts.
Your marble mod is now complete! Now go enjoy your new rumble, rather than POP POP POP!
