Suzuki Intruder vl250 debaffle

[la 102]

anyone out there with a vl250 intruder, i strongly suggest debaffling it!
i did mine last night....in the dark....at 9pm, and im only 17. so you should have no trouble at all doing it. sound afterwards, it is sooo good. sounds like a real throaty motorbike. nice and deep, crisp...all of that. :scooter:

How much of it did you do? Just a few holes in the back plate or did you use a 1" and 3" hole saw to get the plate out and then pliers to break the inner pipe out?
One of the salesmen at my local dealer told me "It won't be a problem with warranty so long as nothing goes wrong", which makes me not want to do it, because I've had to have mine in for a few adjustments already, I'd hate to have to pay for that sort of thing.

the end of the exhaust was really tough for me, so i got a holesaw piece that fits nicely over the exhaust tip, the little thing sticking out. i holesawed away until a had a nice indent, i didnt cut all the way through. just cut a small dent. then i used a hammer and chisel, i hit the indents i made with the holesaw, and created a series of holes, around the baffle. then i pulled the baffle out with some pliers.
basically just holesaw into it a few mm. then chisel through, chisel is way faster than trying to holesaw it. the exhaust is really tough to drill also. so thats the reason i used hammer and chisel. much faster.
i created a exhaust plate exactly like the stock one, so when wof comes i will screw on my plate and it will be back to stock sound levels.
the first time you ride after cutting some of the exhaust out, it may backfire.
if it does it will only backfire once. i had mine backfire as i hopped off at school, and thought 5hit i ruined it, but i found out, via research , that its normal and wont happen again.
let me know how u go
cheers

i recommend cutting out just around the baffle, you dont want to cut out the width of the exhaust....it would be too loud for w.o.f. unless you make a stock plate to chuck back on, like i did. i dont have a welder so i didnt cut all the exhaust out, so i have something to screw my plate on to.
:sweatdrop

[stanleychung]

would you be kind enough to take a photo of what the final result looks like? Just out of curiosity. Thanks

[la 102]

ok ill try get around to it in this week sometime.
quite busy at school with exams coming out my ears.
will be putting photos on asap though.

[Irontusk]

Shit, what I would've done to have a bike in school.. especially a noisy VL250 (the only bikes I ever saw at school were a few GNs and an FXR(?)150), I was stuck in a car though.
Yeah a photo or some indication of sound would be awesome.

[la 102]

i worked a year for it...all weekend every weekend. =[]
ill get photos tonight or 2morrow night hopefully.

[la 102]

sorry lost my camera =[
there is a photo attached, it shows the template i used,
it is dark outside so cant take pic of the exhaust.
will get round to it hopefully.
very basic, just cut out template and bolt in. then remove and chisel around the baffle, put back on to silence it.
yes, i was worried about back pressure and stuff, but i took the risk and absolutely nothing was wrong with it. sound gains, and faster at higher revs.
:apint:

[re_animate]

I'm getting my first bike soon, thinking of an intruder. I'm not too fussed with what i'll be riding over the course of my learners but i would like it to be bad ass :P

and preferably, sound like a 600cc haha

So what's all this debaffling your bike. Could someone explain this to me in noob talk?

Refer to this for a good way to modify your exhaust without failing WOF the moment they start the bike

Baffles are the packing and "maze" work inside a muffler that reduces the noise coming out of the exhaust, as well as adjust airflow out of the engine.

Different bikes have different styles of baffles, and baffles range in designs and adjust ability.

The type of baffle they are talking about, that is common a lot of bikes, is one that has a plate that seals the end of the muffler. The plate has a small outlet tube in the center, that runs into the muffler and often has a reducer followed by a channel. Those mufflers also tend to have a labyrinth of plates further back in the muffler as well.

Ive got a vl250 which had been debaffled by previous owner (bike had only done 4000km) when I bought it) and it sounds great. Certainly stands out over the stock muff... Get heaps of people asking what cc rating the bike is coz of sound and previous owner took off the 250 sticker.

I started riding on a 2006 Hyosung GV250, which is very similar to the Suzuki Intruder 250 (Hyosung made Suzukis under license for some years). The baffle plate on the GV250 was pop rivetted on, couple of minutes with a drill and a magnetic ended screwdriver to retrieve the rivets from inside the muffler and she had the sweetest sounding exhaust. I've just sold her (moved up to a Suzuki M50) and the new owner doesn't want the baffles refitted.

Now, de-baffling the M50, that's what I want to know how to do. The factory fit exhausts do too good a job of keeping her quiet.

I modded the baffle of the Venox and gawd, it sounds like a sexy beast now!:Punk:

[Jerry74]

I debaffled my old M50 yes it did make a great sound performance was slightly better.

Or you could save your $$$$$$$ and buy a larger cc bike and fit Yoshis even better!!!!!

Do you get to Pukekohe often? I did mine, takes 10 minutes, I've got the hole saws.

You can look up the video on youtube as well.

[Jerry74]

There are heaps of how to vids on youtube.

Drill slowly and use a cutting oil to keep metal cool.

Proven method. If I can make a 250 parallel twin sound better than a stock m50, then try it on a m50

I've got a thread in Bike and Product Reviews on the new bike and I'm loving her!

They had 151 bikes at the Easter Egg Run in Tauranga this weekend. The day started rather shitty which must've keep some people away, but cleared up into one of those beautiful blue sky Bay of Plenty days. Saw a few Boulevard M series, one was an M109R in the same colour as mine which had been converted to a trike.

I had a fantastic day, went on the run in the morning, had a lunch date with the wife, then popped over to Katikati and back just to stretch the muscles. All in all, a wonderful time.

Here's what a standard Kymco Venox sounds like:

:devil2: Definitely does not sounds like a 250 now! :Punk: Oh yeah!

Sorry to bump this thread again, but ive just got my 2007 intruder 250, and want to debaffle it. Ive already drilled half a dozen holes in the end plate of the exhaust, which did make it louder. One thing i dont understand is the whole making of a stock loooking plat to "bolt back on" if need be. How do you bolt it back in if youve cut it all out to start with ?

Hey, that sounds quite good mate :niceone:
Here's my poor quality debaffled 250 http://www.youtube.com/watch?v=H_iagwT6yMM&feature=plcp I need a real camera.

A CBR400RR Spada [from description]? Unusual beast... What's happened to it since?

I finished it, fresh paint, cam chain tensioners etc, was mint. New owner did something to the fairing mounts and headlight mounts, painted the engine matt black and generally fucked it up IMO. Somehow ruined it and then it was sold on again, I think after 154(or 7?) thousand KM the engine got a bit sad. Tis a shame the guy who got it from me ruined it, was an excellent wee thing and I regret selling it

[secki]

So back to the intruder 250, can anyone help me with debaffling? It seems near impossible as the rear plate is fixed, ive drilled holes in it, and also around the small pipe sticking out of it but am at a loss as what to do now?

Long pointed bar/big hammer.
Done.

You could try cutting off the pipe that sticks out?

Anyway, overdoing it could result in you having to re-tune your engine. If you're happy enough with what you've done so far, leave it be. When I had the baffles on the Venox modified, I'd originally wanted one pipe done only, as I didn't want it too loud. Peter from Custom Chambers said "I'm gonna have to take them both off anyway, and if you find later on that it's not loud enough and come back, that's double the money you'll pay for the same result!"

So hesitatingly, I said OK and he modded both baffles [with quite some effort to get the baffles out in the first place]. As it turned out, they were too loud - to me - even if they sounded like sex on two wheels. On the motorway, it sounds like I'm riding a Spitfire with a Merlin engine (http://www.youtube.com/watch?v=fNJ8rIEPLOo). But they should (just) pass WOF and I've whacked it a bit to get it a little quieter, so that it sounds like foreplay on two wheels now - good enough for me. LOL

I still have my debaffled VL250 muffler (I bought a secondhand pipe to debaffle, so I could swap my original back on when it came time to trade the bike in for an M50, did the same with that bike and still have those pipes too from when I traded that in) It's all in excellent condition except for some burning to the chrome on top of the muffler chamber (the father/son I bought it off forked out for a new muffler because of it, it never bothered me though, not particularly noticable and not noticable at a lot of angles). If anyone is interested in buying it send me a PM or just reply here, that way you can keep the value up if you trade the bike at a dealer.

I also have a spare tank (1 very small stone chip) and a spare front guard that I picked up from my dealer, has a graze on one of the front corners, I had plans to do some sort of paintwork to them but never got around to it.

And from memory it did sound a lot better, it was a few years back though.
