AZ Kev It's a little late to chime in now, but I have to ask - why the big fuss over the popping? (of course, with those after market pipes, it may be REALLY loud).

I was thinking of marbling or coastering, but I have come to actually like the sound - it sounds pretty tough to me. I have the stock exhaust, and it really isn't all that loud or annoying to me.

I guess it's all just a matter of prefernce though. I like mine the way it is, but am glad you were able to figure your issue out. I second what OlHoss said - which hose was it??? The vent hose maybe...?

VoIPDoc Assuming you have eliminated all leaks, you can stop the popping!

Start over.
1. Turn both mixture screws (pictured) in 'til they seat (stop). Don't force!
2. Turn both out 3 full turns (with the tool I use (pictured), I can only turn the screw half a turn so I turn it 6 times).
3. Run (ride) the bike. If it still pops on decel, turn out 1/4 turn and ride the bike again.
4. Repeat step 3 until popping becomes a rumble or stops.
5. If one side continues to pop, turn that side another 1/4 turn at a time 'til it stops.

Look closely at how the carbs are connected to the cylinders....the carb on the right is connected to the rear cylinder (left exhaust).

Edit: Just read KM suggestion regarding higher octane...GREAT advice!!

Knifemaker Well, if you are sure there are no air leaks...at the carbs, the reed valves, exhaust, and how ever you plugged it.....not sure what would help other than downshifting harder.

I assume you are burning regular gas. Now it might help to use a higher octane fuel. Although I'd just live with it...(I actually liked the sound) higher octane gas is more resistant to igniting... so it might help. May take two tanks or so to dilute out the regular gas .....
