My 02 KDX has a PC pipe and silencer , The question is If I take out the packing will this Harm my performance ? I konw the noise level will hit the roof , thats O. K . I have also had the top end punched to 240.
I think the short answer is it will take away power everywhere, and make you not very popular with riding friends or neighbors.
My understanding is that pipes work by creating pressure waves to improve cylinder scavenging. When you alter the back-pressure signal, it messes up a baseline assumption that someone designed the pipe around.
As an aside, I do believe an unsilenced pipe can make more power, but it would be designed from the beginning to run without a silencer - like GP roadracing bikes. However, E. Gorr and others may have a better technical answer - I defer to their depth of experience.
Besides convincing Joe Average that dirtbikes are just as loud and obnoxious as the Sierra Club always said they were, it will kill your low-end power.
I'm just wondering why you would want to remove the packing anyway?? Screw the packing just remove your silencer... That will give you the same effect w/ less work....
Done it, sounds like sh*t, lots of popping and pingging, power level fell to zero. As for Yz Joust's idea I have had to move my bike once with the silencer off, 30 meters and 6 bc powders later I would say don't try it!!!!
Heck, why dont you just take off the exhaust right at the head. Yeah, toss that pipe and silencer all together. Thats what I did. It sounds really cool. Sometimes when I hit a puddle the water splashes up there and makes neato popping sounds, that is when I can hear it, because I made the bike so loud that I and anyone that I ride with have to wear earplugs. It also comes in handy when I get seperated from my group. I just rev the bike three times in a row, ya know, like SOS and they can find me.
As if I have to say it, because some doof out there will think I'm serious, I'm purely sarcastic. Dont be irresponsible and ruin it for everyone else. It might be okay with you to cause noise pollution, but stop thinking of only YOU.
Crap like this is one of the reasons why riders in my area have been kicked off local riding areas.
Thanks Everyone ! I get the Point ! I was just wondering what the effect would be . I am gona run to the Garage and Jerk the pipe off Now ! LOL :think:
