Exhaust

[Casey]

Hello all,

I have a sickness which causes me to want to upgrade performance on everything. Cars, computers, etc. My physician has told me that it's incurable.

Anyone ever tried a custom exhaust for their scoot? Such as Leo Vince, etc.?

I'm looking at a Leo Vince exhaust (for Majesty 400) on amazon. http://www.amazon.com/Scooter-Exhaust-YAMAHA-Majesty-2007-2007/dp/B...

I'm wondering if they make a noticeable difference in power. And are they awfully loud? At my age, I've outgrown the need for loud exhaust...  :)

Here is a link to a page that says the system produces a "deeper tuned tone at a reasonable sound level" and than there is an "optional silencer insert as quiet as stock."

My preference is for making scooters quieter.  Caution is warranted when a company sells a muffler for their muffler.

See the review page at Motorcycle Supersore for a few comets.

Thanks Rick--wow it gets good reviews. When I have all my nickels and dimes saved up, I'll probably get one. If it's too loud for me, I'll try the silencer. When I get it on, I'll report back.

Hi Casey...now i havent been a member with this group too long, but modifying small scoots and everything else i have seems to be a bug we share.

although i havent done any substantial mods to my burgman yet ( hell, i only got it yesterday, but gimme some time ) i have done some serious custom work on small scoots ( ho9nda ruckus and metro) in the 50-150 size. that said, it is very likely that adding the exhaust alone to your scoot will in fact lessen its performance. why do i say that ? because these engines are even more sensitive to backpressure and you will in fact lose bottom end torque, or in other words, the abilty to accelerate quickly. there is some wisdom to being "heard" better and of course the right exhaust looks bad-ass, but until you understand that your engine operates most efficiently,power and mileage, when left in stock form. you can add an axhaust OR an intake setup, BUT, if you do both you will you will require some sort of fuel system manager( injected scoots) or jetting (carburated scoots) just to regain the lost power and or add up to 10 %....so all in all, consider your mods for looks only and dont believe the manufactures hype.

now if you really want to make a difference, there is a TON of stuff you can do in the CVT system to launch harder or go faster ( you have to choose one or the other as you cant have both). hit me up if you need some more info on that.

 

good luck in your coping with the mod bug.....your wallet will suffer more than you will !!!

Thanks Gary, everything you've told me jives with what I've been reading on my research. Since my original post, I purchased the J. Costa variator, and got quite a pleasant boost in torque. The scooter definitely has more scoot! :)

I will probably put the Leo Vince on the bike due to my sickness about fiddling with my autos/bikes. If I notice a reduction in performance, I'll go back to stock. I have looked in to fuel system managers, etc, like the Power Commander. I've read that the Power Commander isn't very effective on the Majesty, as something about the Majesty design only allows the PC to do 1 or 2 tweaks, and not the full meal deal. So I'm holding off on it.

Right now I'm enjoying the J. Costa immensely. It's said that it is the single most effective performance boost for these CVT scoots, and I believe it!

Thanks for your reply and info!

I out one on a Bergman 650. No diff in performance or sound. A waste of time and money Plus it. Killed any warranty because it was a third party vendor.

I'm liking it! I knew not to expect a big boost on performance. But I like the appearance and the sound (it's a little throatier). This combined with the J. Costa variator is a good little package! We're not talking about crotch rockets here, but my scooter definitely has a bit more "scoot"!

If anyone is a fan of low end torque, and would like to have a zippy take-off, then you will love the J. Costa. Can't recommend it enough. I believe it is available for most scoots. If anyone is interested, you have to order out of Europe, so if you have difficulty finding it online, message me and I'll link you up.

My bike likes the J. Costa, my brain likes the Leo Vince exhaust!  :)

Hi Casey,

Do you still have the majesty?   I now have one and have that sickness too, but mine is a much milder case.  I would like to change the mirrors so I can see behind me better and would like a taller windshield.  The current one is way to short.  Would like to get the J. Cost variator and would like a throttle control that is less sensitive.  Its a little jerky riding at low speed.  I have installed a top box, new air filters....those things get really really dirty and are quite expensive.  Wish they had ones that could be washed and reused. Getting around 56mpg...probably because I am a little lighter on the throttle ;-).

[Casey]

Hi Roger, congrats on the Majesty! Yes, the mirror extenders are the first thing everyone wants, otherwise, all you get is a nice, clear view of your shoulders.

I think the Majesty is the best large scooter, due to it's appearance and HUGE storage capacity. The J. Costa variator is the single best after market thing you can get for your bike. That torque at the low end is lots of fun! You lose a bit on the high end though, taking a bit longer to go really fast. But we don't go really fast very often, do we? (or maybe it's because I weigh 220--which was one of the main reasons I got a big scoot)

I also got a top case, making this scooter carry more than some cars! (over stated, probably, but still...)

I got a taller Givi windscreen. I commute in the country and boy those filters get dirty fast! No washables yet. I even sent an email to K&N. They make K&N's that fit everything but the majesty. They said there are no plans to make them. I wonder if a guy could buy some K&N's and cut the inner material and put inside your majesty filter frame. It would be a lot of work.

I'm getting around 53. 

The Leo Vince exhaust doesn't do anything but look shiny and give a more manly growl. I wouldn't have gotten it except I ran across one used for very cheap.

Enjoy your scoot! What color is it? I put 7000 miles on mine commuting last summer. It was a fun summer! I was shocked, however, that I wore out my brand new rear tire in one summer!

Hi Casey,

My Majesty is a red 2008.  It had a little over 8000 miles when I bought it and I have put another 1000 miles on it.  Replaced the rear tire at 8900 miles.  Found a Majesty forum that has some interesting information.
