Hey guys,

I have just installed a new Delkevic full exhaust system on my 04 VFR and it is now blowing flames from the rear left pipe.

Just wondering if anyone has any ideas on why this might be happening?

Thanks in advance for your help.

Cheers Steve.

Flames from/in the pipes can only be caused by unburnt fuel reaching the exhaust system or oil contamination in the pipes.
Are you sure the bike is running on all 4 cylinders ? If yes see below.

How far have you run the bike since fitting the system ?
If not much then give it a good hard run, to burn out any packing oil in the system, better to run at high revs in second or third to get plenty of high speed hot gas through the system. Then check it again, should be gone.

Strange it's only out of the left as both are fed from the same link pipe, so I suspect it's just oil in the can burning off.

sounds islly but on the VFR's the heat goes out the left hand pipe and the noise comes from the right hand pipe. Why it is not the other way round is beyond me but hey, that's magic for you.

Awesome.

How can the rest of us get that???

That was my first reaction too. I don't think we get the Delkevic "Flamethrower" exhaust in Canada, must be an Aussie thing. :goofy: (I suspect Mowhawk has the right answer.)

Hey Guys,

Thanks for the reply.

I have only run it in the Garage at the moment. I have reinstalled the baffles and flames are no longer..

I think Mohawk was right.

as for switchblades comment I have not done the computer as yet and i have installed both of the O2 sensors..

do you think it is worth buying the power commander V?

Thanks again.
