Running hot since exhaust install

Hi Guys sorry if this was posted before.

i installed a slip on today on my 2009. Sounds a lot better and really removed the flat spot it had.
but since installation the bike runs a lot hotter. Haven`t let it stand and idle to see how hot it gets but freeway i on average 6 degrees Celsius(42,8 F) hotter and town runs roughly 98 - 108 (208 - 229 F) on average should i be concerned? no power commander installed as i was under the impression thee babies run rich from factory.
also the tailpiece heat shield was removed but i doubt that would cause it.

all help much appreciated.

Are you saying its at 208F while you are riding?
If thats the case then yeah I would check and see. I also believe the fans are supposed to kick on after 220F or something after that.

Yeah that's definitely not normal. I get that hot idling in traffic on a hot day but on the hottest days I rarely exceed 178F on the freeway cruising. Hottest I've ever been idling in traffic on a hot day is 224F I believe.

Slow riding, coasting and stopping at traffic lights. fan does kick in at 220 or there about. so its not like its overheating. it has gotten hotter than that before with standard pipe but what worries me is how quickly it reaches those temps

it ran about 178 on freeway where it usually runs 165. but i must say it was stable at 178 not going up or down.
till reaching town and at stops it would bump up to about 220 where usually it would be about 210

Being that the end of the exhaust is no where near the front of the bike, the thermostat or the cooling loop, I have no idea how this could happen.

What slipon? Did the slipon come with it's own gasket or is it a bare slip joint?

Temps seem normal to me though 165 degrees on the highway is VERY low, lowest I've seen after the bike warms up is ~170 degrees with 175 or so "normal".

Personally I think you are fine, you sure you are not mistaken on your old numbers? I've always had ~175 running down the road and ~220-225 in stop and go traffic with the fan kicking in and off as normal ranges.

Two piece airage slip on. Both joints slip on bare. may be worth while to note that bike is NOT decated neither has the flapper mod been done. so i just cant see how this could cause the problem. im stunned

Absolutely positive about the numbers. Actually beginning to wonder whether the standard pipe wasn`t the problem and its only running proper now with the slip on

but your numbers put me at ease abit. ill commute with it tomorrow and see what it does.

Does yours have slip on? or PC?

165 does seem low. My engine/exhaust is bone stock and has never ran under 173. In the summer it won't get below 178.

As stated your temps are pretty standard. I have seen mine drop to 168 degrees while riding interstate but its rare to drop below 170..

If you are worried flush your coolant and recheck your numbers.. Bike is probably due for it anyways..

I never had a slip-on but with a full exhaust it didn't lean out enough for the temps to spike like that...I'd check the cooling system, and recommend using engine ice if this is just a street bike.

It had an Akra slip on on it when I had an RR; sold it last year. No PC, no need for one.

That's incorrect. EPA would never allow exsessive emissions that is a rich mixture. These things are almost danger zone lean from the factory. A full pipe would make it leaner. A slip on won't change anything.

I you changed ONLY ONE thing (and it's NOT a hotter day, or you're riding the bike harder, etc) then yeah, it's the pipe.

What else could it be?

While it's true you may not NEED a PC, it will optimize fueling and likely lower temps a bit.
