Questioning sounds of new pipes

[Eleanore L]

O.K. So I put on some HK 3s, K an N filter, and pclll mapped by Jamie at fuelmoto.Sounds great, rides stronger, but I think there is just a little backpop on no throttle decel for just a short period of time. Question 1 Should I remove pair valve? #2 Is this just normal? #3 Should I have it dyno tested? Jamie said it should be about 90% accurate. If I let it idle, give it some gas while in nuetral, I smell gas like its not even exhaust. Thanks for all input.

I think with aftermarket exhaust a little popping is unavoidable. You can remove the pair valve with no effect on performance. Actually it will improve just by removing 5lbs of material. Dyno is a waste of time and cost unless you plan on tracking. You will smell some gas at cold start. Double check the torque of head bolts. 17ft/lbs.

what is tracking?

I just installed Cobra Slashdown Speedsters a PCIII usb and a K&N filter on my C90 tonight and it runs GREAT, no surging, smooth power and sound.

However, like you said, while coasting down in gear RIGHT before you reach idle speed on the coastdown you get a few pops. I hope its normal. Anyone have any sound clips? Ill try to post mine.

Im a bit worried, but the bike runs great.

Kodatech congrats on pipes its like a whole new bike Sounds like you and I are maybe just normal sounding. Ive called a few people(even my dealership) and they said some popping is o.k. I think I am going to do a little more research on the pair valve and maybe discontinue its use. I tried to get sound byte but didnt come out to good from my dig.cam.

yeah im glad to hear someone else has the same sound, mine is just before it reaches idle on a coast down. I have removed my pair valve completely. I woke up pretty sick this morning, i was going to take a video of the sound, ill do it this weekend.

valve removal did nothing to change the sound of my bike.....it does look ALOT nicer now though. :O)

hey for the pair valve go to Moccs Place.
I even got the kit for complete valve removal from him. $21 shipped.

Did you notice any different sounds from the K&N filter?
