Baffle in vs out MPG

Due to the events of last weekend, I hastily decided to stick my baffle back in the Scorpion.

Firstly, I hated the way it sounded. At tick-over it sounded like a hair dryer. I wouldn't of minded if it was a jumped up hair dryer, but it wasn't even that! When it was running, especially at speed, I couldn't here it.

In fact, I almost cried on Sunday when I could hear petevtwin's bike BEHIND me. I did get some kind comments from one of the guys on Saturday, but that was because it pops & bangs, which is down to air leaks.

So Sunday afternoon, the baffle feel out again. The results of the fuel tests are now in, thanks to Monday being sunny (and it would be rude to not go to Ponderosa in the sun!).

With the baffle in, I repeatedly got around 115miles to a full tank before the flashing light. With the baffle out, on exactly the same run, at roughly the same pace (so the only thing that's changed is the baffle), I got 138miles before a flashing light. I even filled the tank at the same petrol station!!

So.............

Loud pipes not only save lives, they save the dwindling fuel reserves.

Nice to know that I'm doing my bit to save the planet.

But yours is so loud it is killing all the wildlife! I could hear yours above the the sound of my Renes and with ear plugs in!

Very interesting Baph. I have never noticed that before, saying that I have only had an exhaust on with a baffle in once and that was last September for the MOT.

It certainly makes it beneficial to keep it out now though!!

i must admit pete it was loud , i could here yours above mine when you were behind me. but i loved the sound

With the baffle out, I couldn't hear sod all, just the way I like it

Whoever it was that commented on my can outside Pete's Eats (neo79?), you really need to hear them with the baffle out

Not quite as loud as pete's, and Luckypants' might be a tad louder than mine, but I definately can't hear anyone else when I'm moving, and I drown out a fair few bikes.

its a good job you wert out with me viper & squiral hunter on the weekend then

Do you worry that it could be leaning out the mix enough to damage the engine? It explains the mpg difference

TBH, I'm not that worried that its enough to damage the engine, but it's on my todo list to get it checked.

I have always ran my bike with the baffle out , and had it serviced once a year properly by the dealer. not had anything back from them to tell me the engine is looking a bit worn etc. even after last years big 15K er and the shim check. the shims were well in limits
