Yo guys! I love the sound of the F4i without the pipe but worry about burning the valves like people have said.. that it's horrible for the bike because it causes it to run lean. Will a Dynotune correct this issue? Also, what's the difference between having a shop Dynotune vs. buying a power commander and doing it yourself? Sorry for my ignorance about this stuff - I don't know alot about it haha. Thanks!

 

Burning the valves doesn't make the bike run lean, the lean running is what burns the valves. Just don't run no exhaust and you'll be fine and sound as terrible as you are trying to. Headers to just a piece of pipe out back.

 

You sound like a girl. You PMsing or something bro? I know that the lean running burns the valves, and you didn't give me a solid answer of whether a dynotune would fix that problem, but instead gave your opinion that a str8 pipe spounds like sh*t. Thanks, man so much help.

 

Solid answer: A tune by a professional on a VERY expensive piece equipment on one bike with certain mods on local fuels in the conditions it will be running in will always be better than a generic download off the internet.

Don't insult our ladies. Most of them sound, and spell, better than you.

Boredandstroked gave you some good info about lack of exhaust. If you don't like his response, wait for one you do...

 

LL. Thanks for the solid answer bro!

 

Limited on my topic knowledge here but I thought I'd offer just my thoughts.
I've had several of my mates run power commanders and when we pull in for yet another coffee it's always the same. Tweek time ! Try this try that ! Does my head in !! I think rights right and wrongs wrong. Get it done correctly and leave the **** thing alone.
Exhaust noise for me is always about quality. My bike, with no silencer sounds nice for ten seconds then my ear tells my brain something's wrong. No quality.
I like Ducatis but mines a Honda, it is what it is. If you can't find a decent silencer with a note you enjoy then maybe you need a different machine ?
As an ex 2 stroke rider with twin micron expansion chambers who used to scream around I can assure you I have nothing against loud pipes lol

 

I recently installed a voodoo shorty. ( Small resonator inside a short piece of pipe) Voodoo assured me that the engine would be fine. I did run without a pipe for 50 miles or so, very loud and Poppy, was ridiculous. Put the shorty on and it doesn't pop anymore, but still very loud. There are too many idiots in cagers. I feel safer being loud.
Also, I no longer hear the CCTL rattle!

 

My advice was solid. Tuning doesn't help. Not letting cold, fresh air hit your valves does, so run a strait piece of pipe. /story.

 

Another advantage to a shorty is not worrying about smacking a muffler into anything, usually while parking.
