when in first and second gears in low rpms, with a little throttle when cruising around the exaust makes a sound like its a harley. its a low, almost studdering/popping sound. it doesnt seem to affect perfomance at all, just sounds odd. once i get on the throttle the studdering sound goes away and a nice consistant tone takes its place. i just wanted to know if this is a common sound for our yoshi pipes. if i can get a chance ill post up the sound. i bought the bike used with the slipon already installed.

it has had its plugs changed, carbs cleaned, jetted and synced, air and fuel filters replaced.

 

how low are the RPM's?

 

maybe 1-2k, ill have to check today on my way home from work, i have a garage that i have to drive in low rpms in.

 

sounds normal to me, as long as it goes away when the revs go up I wouldn't worry. I take it the exhaust baffles have been removed.

 

i dont know, it doesnt look as if anyone had the can open, unless you can remove the baffles w/o taking it all apart.

 

some of them just have a screw under the outlet pipe right at the end of the exhaust, you unscrew it and then can pull the baffles out with some pliers. You can't do it on my scorpion (which is a shame) but then again it keeps the police off of my case.

 

I just got an rs3 in carbon fiber----haven't installed it yet but I'll let you know what happens when I do

the popping noise/tone is most prominent around 4.5k rpms in second gear, it happens when decelerating then holding around those rpms. im sure its nothing, i just want to make sure everything is copacetic.

 

I wouldnt worry about it, sounds similar to the way mine was. Now cut that bitch down to 10"s and go bother people.

 

thats the plan , just have to pop the rivits out. it will be my winter project, among other things.
