Hey guys, so my bike ran great for about 2 days, however yesterday when I went out and started it it was acting weird. The bike itself sounds different (engine and exhaust) its lower sounding instead of higher like its always been. Also it feels like 50% of the power is gone. Il put up a video whenever it finishes uploading. My last problems were just the spark plugs, I still have the old ones in it, that may be the problem but I dont know. Help please guys, thanks!! Hope this makes sense

 

 

Try a new key chain. LOL

Hmm? It does sound different.

 

lol i know, sorry about that,I just found it so i put it on in case i lost it, it would be easier to find.haha I have no idea what can cause a bike to sound different, it sounds like a dang ninja 650 or sv650 = annoying vtwin sound.lol Not the screaming cbr sound It should have.

 

Does the F4i have an HTEV in the exhaust?

 

HTEV???? Im not sure, if its something electrical I dont belive it does. I took the whole headers off to paint them, no wires were connected. and there is nothing in the muffler.

 

It's a cable driven valve in the down pipe. The 929s have them. I was just wondering...

Is it puffing dark smoke like its running too rich?

 

No, I dont think its smoking,however i just propped the tank up and i smelled a strong smell of gas like its being flooded.

 

Just read up and found where a few guys had similar problems. They were told to get a power commander to adjust the fuel. I really don't want to go that rout and it not be the case.

 

You have something else going on. I gotta think for a bit...

You smell fuel? Leak? FPR line?
