Anybody recommend the (8) 5/16" drilled holes or the 4 1/2" drilled holes. I noticed a few people had the (8) 5/16" holes and really liked it with no jetting and that is kind of where I am leading! I am out for a little louder exhaust. Nothing extremely loud!

Just duplicate the other guys picture and you'll get a very nice sound. The sound is louder and throaty but not loud enough to get you pulled over

Re: Louder exhaust sound Reply #17 - 04/29/12 at 21:56:50 Drilling a 1/2 hole takes a lot more Ooomph than a 5/16ths, 8 small holes would look better than 4 fat ones, IMO, & you may run into something inside that jams up the bigger bit, we can see a pic of a very successful job. Id do it that way. 4X1/2"= .7854 square inches 8X5/16" = .6136 Or maybe Im not gettin that rite,,

Routy

Could you post the link or url to the posting of the white spacer mod that you did? I looked for it but was not successful. I'd just like to see how it is done so I can eventually do it. Is it all instructions telling you how to do it or is it pictures and instructions. Anyways if you could help me, I'd be a happy camper.

I ended up putting 4 5/16" holes in the end plate baffle and will be adding four more tomorrow after work. Just in the same order as you. I also ordered a powerstar spark plug tonight. Going to try that out also.

Thank you.

Jacob

Jacob,
I really never posted or pictured a how to. I just warned (cautioned) about the 2 little bitty screws that are very tight. Some say you can use a little HF impact driver, but I just used brute force pressure on the driver,....don't let it slip !
Other than that, can I remember ??
You take the tank off (or twist the carb) and take out the 3....or is it 4 screws that hold the cover on top of the slide that contains the needle/white spacer. Then comes those 2 little bitty screws.
If you not scared of carbs, not a problem.

If any of this is not correct,...help !! Shocked

I'm a new owner of a 2005 Suzuki Boulevard S40. I've been lurking for a couple days now, and glad I found you folks. So, stock exhaust on my bike, and I agree it's too quiet...I like the idea of drilling 8 - 5/16" holes in the existing muffler. How deep do I need to drill these holes? Cheers, Dave

I am! Just do it same as Routy in this post. It's only like 1/8" think plate, if that. You'll know when your through. Good luck and hope you like it!

Rejetting is a matter of different conditions and/or opinion. I myself saw no need to rejet.

Yup, I did...so much info that I'm trying to get it all straight. Wink

The re-jetting sounds simple enough that I could do it with breaking anything (I'm pretty handy, but haven't worked much with engines). I'm trying to figure where removing the plug in the carb fits into the picture though, and if re-jetting is still necessary after removing the plug.

Regardless, not planning to do any carb stuff anytime soon unless drilling the exhaust kinda requires it to keep the same torque/HP. I'd rather get some seat time first and get accustomed to the bike and riding. I'm a new rider, and learning a lot of stuff at the moment. Tongue

Cheers,
Dave

If it runs good, ride it. If its a bit lean, you're not going to hurt it, unless you are really horseing it hard,......like WOT on a hot day. Do a S plug read after a good run, if it not white like hot, don't fix it, ride it !

The idle mix screw is just that,....it controls idle to fast idle speeds. It does nothing for running rich/lean at speed.

Other than the louder and a bit deeper sound it gets heads turning. And I mean that in a way that people, and cars notice you more, making it justa bit safer . Which to me is the main advantage of the louder pipes.
