hubbsfd Posted June 4, 2013 #1 Posted June 4, 2013 I added my questions to my updated review of the National Cycle Peacemaker slip-ons but I don't think our forum experts read it so I'm going to re-post for some helpful advise. Question for all you experts out there.... I hear some minor popping from the exhaust after installing the Peacemakers mufflers. Mostly when the pipes are in wide open state during throttle down but a little even in quiet mode during throttle down after rev. I have always adhered to the concept that only changing pipes or only air box (not air box on an RSV of course) that you do not have to rejet the carbs. My 2008 RSV has no mods to the air box so I shouldn't have a problem with just opening the pipes some. If I take it to my mechanic will they be able to adjust the carbs to get the popping out or will they want to rejet? This shop does have a dyno so they will likely advise doing a rejet on the dyno. Opinions?
etcswjoe Posted June 4, 2013 #2 Posted June 4, 2013 Did you resynch your carbs? Should not have to rejet.
ACE50 Posted June 4, 2013 #3 Posted June 4, 2013 synch carbs, get rid of or plug AIS, open up pilots screws a half turn or so. No rejet needed it your carbs are in good shape. Mine runs like a bat out of hell and still gets 42 hyway. A slight more mods than you though.
garyw Posted June 4, 2013 #4 Posted June 4, 2013 What you are hearing is called after fire. This is due to a collection of unspent fuel in the hot muffler, especially after a high throttle. Stock mufflers have devices inside to counter this. I used to get a bit of after fire even with the stock mufflers while down shifting from 70 mph or so. Mine seems to after fire more cold. After it is warmed up well it is greatly reduced.
rickardracing Posted June 4, 2013 #5 Posted June 4, 2013 Research on here plugging the AIS system. Once you do that, all will be right with the world.
hubbsfd Posted June 4, 2013 Author #7 Posted June 4, 2013 I found the info on disabling the AIS system. That does sound like it would fix it. My carbs were recently synced prior to installing the new slip-ons. Would this need to be done again after the slip-ons?

hubbsfd Posted June 4, 2013 Author #9 Posted June 4, 2013 I would reccommend you do the carb synch again. I have a brand new Motion Pro still in the package. Guess I'll get my feet wet and try doing it myself. I've read a bunch of folks don't like the Motion Pro sync tool. I hope I don't run into all the issues others have mentioned with this tool.
ACE50 Posted June 4, 2013 #10 Posted June 4, 2013 Motion pro will work fine, just that there are much simpler, quicker ways to do it. No fluids involved........

I have the Clymer service manual so I will look those up on the carbs. I should find them in that manual right? And... open would be which direction a turn will be in the manual also?
Freebird Posted June 4, 2013 #12 Posted June 4, 2013 Doing the carb sync is very simple so it would certainly not hurt to check them but to be honest, changing the mufflers should have no affect on the carb sync.

Bottom of carbs under small tapered caps (have to knock them off to get to them if still there) Counter clockwise to open them up. Plug AIS and sync first though to see if that fixes it. I've gone with one size larger on pilot jets. Starts easily without choke. Off idle response is great. Mine are 2.5 turns from lightly seated.
Kirby Posted June 4, 2013 #14 Posted June 4, 2013 :whistling::icon_lurker: :stirthepot: I thought surely this topic would arouse someone's attention. I'm a little let down.:think:
hubbsfd Posted June 4, 2013 Author #15 Posted June 4, 2013 Not sure who you were waiting for or what they might say but you got my curiosity going. Anyway, just plugged AIS and pop is gone. Carbs were just synced a couple weeks ago so I decided to just do the AIS block. Works good. I will play with the pilots a little but I'm pretty happy now.
hubbsfd Posted June 4, 2013 Author #16 Posted June 4, 2013 I'm done. It's all good. Thanks once again all!!!

djh3 Posted June 5, 2013 #19 Posted June 5, 2013 What no mention of sea foam? I'm highly disapointed.
rickardracing Posted June 5, 2013 #20 Posted June 5, 2013 What no mention of sea foam? I'm highly disapointed. Seafoam fixes EVERYTHING!
ACE50 Posted June 5, 2013 #21 Posted June 5, 2013 I think seafoam is overrated! That's right...I said it!
Guest Posted June 7, 2013 #22 Posted June 7, 2013 It will happen be patient.... But why must it happen???? Let him be in peace in his new hacienda!!! Oh the humanity of it all.......
Drreb Posted June 7, 2013 #23 Posted June 7, 2013 But why must it happen???? Let him be in peace in his new hacienda!!! Oh the humanity of it all....... LOL!!!!!
billmac Posted June 24, 2013 #24 Posted June 24, 2013 Motion pro will work fine, just that there are much simpler, quicker ways to do it. No fluids involved........ What would be a simpler, quicker way? Stopped at a shop and they want $140.00 to sync the carbs. Said it would take a couple of hours.
Freebird Posted June 24, 2013 #25 Posted June 24, 2013 It actually takes about 10 minutes. Vacuum gauges or carbtune work very well.
