new slip on

hey i just got my leo vince can in the mail for my cbr1000rr.  it's still pretty new and only has 250 miles on it.  wondering if it matters or not to put a slip-on on a still really new bike?  

I had my 04 GSXR 1000 less than 400 miles and put an M4 slip-on on the bike cause i hate that damn cervo on the exhaust plus i had the bike's fuel/air curve remapped  

think it would really need to be remapped just from a slip on?  I know people always say to do that when you put a full system on, and that makes sense, but just for a slip on? but then I suppose the shop will do all that anyways i guess  

Don't bother with a power commander with a slip-on. Even full systems usually work fine without one. Unless it's running poorly, it's not neccesary. If you are going to use one, do it right. Have a custom map made. We have people come into our shop constantly withthe complaint that ther bike isn't running right. We run it on the dyno and it'smaking 10hp less than stock and it's got a full pipe and PCIII. We unplug the PCIII and it jumps up in power. If they are not tuned right, they're a waste of money.

Back to the question at hand. I personally would wait unil the bike at least gets past the break-in period, generally 1000 miles. But that's me. Another thing you can do is to reset the ECU so that it calibrates itself to the new pipe easier and quicker. Do this by disconnecting both the positive and negative battery terminals. Hold the wires together for about 30 seconds, this clears out the memory and brings it back to 0. Then reconnect the battery and start the bike without giving it any gas at all, not even the "choke". Just hit the starter button and let it idle for about 1 minute.  

I put my Yoshi on before I left the dealer mith my Gixxer.
I had it re-mapped about a month later. It idled a little funny and had a little hesitation in 1st.  

the reason i did was because that damn cervo, however useful it may be, adds a bit of a dead spot off the line when it's not there because there's no cervo to close the flap on the exhaust for back pressure  

realfastbill is 100% correct. If you dont take a PC3 to a qualified person to map your bike you are wasting your money.
I took mine to a certified DynoJet Technician, who wrote a custom map for "my" bike. I have known several guys who just bought a PC3 and wired it to the bike thinking it was helping them. But in reality it was hurting them. I may be wrong, but it seems to me if you make a change like removing the servo valve, some attention may need to be paid to your fuel map. But like I said, I would'nt just go out and buy a PC3. Take it to a qualified tech.  

I agree totally...  

Gixxer's are a little different. First, they only get a muffler, or "bolt-on" techinically not a slip-on. It tends to have less of an effect. Mostly it's a noise maker and loses a pound or two. Second, Suzuki ECU's are programmable. Your dealer can plug up this computer from Yoshi and can change the factory settings without a PCIII, which is real convenient.  

i only wish they had a dyno at the dealership where i am  

The big problem down here in Florida is that our weather and atmospheric conditions are vastly different than where most of these downloadable maps are made. Guys are always saying to me “I downloaded this map on-line that is made for my bike and my pipe”. I’m like, “Well who made it?”  They answer “Muzzy”. Well no *** it’s not working right! Muzzy knows his stuff but he’s based in Seattle!! You’re in West Palm Beach! 95 degrees, 85% humidity and at sea level. You’re tuning your bike for the Pacific North West idiot.  

Hey thanks for the input. I will probably just put it on and not worry about it atleast till I get back to the states.  I just got the slip on for now basically for the looks/sound and plan to put a whole system on later when I return to the U.S.  RFB what part of Florida you at?  That's where I'm originally from, Orlando area.  

I used to be in West Palm but recently moved to Port St. Lucie.

As for the slip-on, you've go the right idea. Don't bother with remapping unless it starts popping or stumbling. I have a full Muzzy on my 636 and it runs fine with the stock mapping. I have a PCIII, but I'm waiting to install it unitl I can get the custom map made.  

That's cool man.  Yea the pipe is just a temporary thing anyways, I plan for a full system when I get settled back in the states.  I don't know, I'll just have to see how I like this can.  Thanks for the help.  

I know you don't need to re-map after a slip on...  But 2 weeks ago I put a slip on on my 10.  Ran fine, sounded good, but you could smell that it was running rich.  A week later, I put the PC (and TRE) in with the map that was preloaded on the PC, and it runs fine, sounds good.  But it doesn't smell anymore.  There is some poping when slowing from hi rpm, so I probably need to do the block off plates...  Any thoughts or opinions on this?  Just wondering....

I pretty much got the PC so I could tinker with the maps a little...
