GDay,

Currently the bike is running what appears to be some Harley Mufflers and even though it sounds ok, I did take them off when wrapping the pipes and started her up, it was obviously louder but the sound was fantastic.



My question is about taking them off and running a small in pipe baffle. As it sits now if the mufflers are removed both pipes are the same length which is important. Tuning wise it shouldnt be an issue i wouldnt have thought, but interested to know opinions.

Also how much difference would a 4 inch baffle make? Thinking maybe something like this? http://www.ebay.com.au/itm/SHORT-4-EXHAUST-BAFFLES-FIT-44MM-1-75-DRAG-PIPES-/251061597073?pt=UK_Motorcycle_Parts&hash=item3a746ff391

Any help appreciated

Cheers Cam :beerchug:

Do it if you want to, I have. Pictures are in my "Stella" thread. I haven't heard it since it isn't running as of yet. I suggest you get the 8" ones, you can always trim them down to satisfy if needed.

Just a reminder, Vulcans aint Harleys. They are finely tuned...*choke*... and precision engineered machines...*giggle*... designed to run like sewing machines (sorry, lol, couldnt resist that). Seriously though, Vulcans need more backpressure than Harleys. Id suggest adding an extra foot of straight pipe (baffle in there) and a nice angle cut end (both pipes). Believe it or not, more length will increase backpressure. Pipes too short can fry yer valves. Did it to my Bonneville.

From a looks point of view i was hoping to go for the short pipes look, if its not going to happen without running another foot of pipe should i just paint these mufflers black and make them blend in a bit more.

Also on another note i wound the fuel mixture screws out to around 1 and half as the front was nearly all the way in and it seems to be throwing a bit more smoke out now, should i wind them back? Is it to rich?

DO IT. They make a huge difference. Put it in the exhaust pipe ahead of the muffler. Got mine here.

I have straight pipes on mine and seam to have a ton of popping on decel, will the baffles help deminish this some?

Don't know. After I marbled mine I never have popping. My engine doesn't pop with the baffles. The low and mid range torque increase is unreal, the bike will still pull 10,000 rpms and the sound is good and mellow.

If you have the stock header length, then yes, will help. But you also need to be careful not to put TOO big a baffle into too short a run. If yer set on running the shorter pipes, then I'd suggest the shorter baffle, and ferchristsake, at least put some turnouts at the ends and dont leave em square (for looks). For popping, also check the pipe seal at the head/exhaust manifold itself. A leak there will cause all kindsa poppin'.

Thanks Wolfie, I'm going to take some pics and measurements this weekend of what I got, I'm just trying to work out all the little bugs on this bike so I can have an enjoyable summer riding, without having to spend a ton of money that I don't have right now. I see your in southeastern NY, anywhere close to Rockland county?

Yeah I have some new gaskets coming.....I'll get straight pipe to add on but not to much hahaha. Getting the longer baffle and will trim to desired sound and don't worry I am going to have some turned out ends as that's the look I prefer and so will my tyre.

The extra pipe will be black. Marbeling sounds interesting but don't really know what I am looking for, any threads with pics on here? Any thoughts on the fuel mixture question I had above?

I'd recommend starting with your pilot screw out 2 1/2 turns. Make sure to turn it all the way in first (snug, but not tight). This will give you a place to start, but you might need to do some adjustment after that. With the setup it already has, you will likely be getting too lean if you are less than 2 turns out.

I don't know if anyone has posted any Vulcan specific carb tuning advise on the forum, but the interwebs have plenty of info. The concepts here can be applied to other styles of motorcycle carbs. Hopefully it can help you nail down your problem.

BTW, I like the wrapped headers. I did mine, too, when I de-goated. Right now, I've got stock mufflers, but I'm going to a 2-1 with a short Cherry Bomb glasspack. I'm just torn between leaving the characteristic red, or painting it flat black to blend with the header wrap.

Good luck!
Hippie

I grew up in Rockland (Pearl River) my mom still lives in Orangeburg. Im right up In Greenwood Lake, just over the county border, and Mattman is right in Tuxedo.

That Google custom search box is your friend. Just type in "marbelling" and you'll see a plethora of threads on it. :smiley_th

I'm over in Bardonia, if I ever get my rear tire changed & get bike inspected, will have to hook up for a ride

Anyone know what headers are on this bike? I want both of my pipes on one side and I'm looking for the least expensive way to do it.. Sorry for jacking the thread.:)
