Jardine exhaust... more power?

Hey guys... I have a Jardine pipe getting delivered later today... as well as some black levers, headlight gaurd, and a nice looking kick ash colored air box cover :) I CANNOT wait to get the goods on there. I'll post pictures as soon as I can.

Anyway... so the exhaust description claims "better performance". I've heard that is bogus. I was just wondering how it could be. I jetted my TTR 230 last year... which entails, as you know, opening the air box intake, the exhaust, and jetting the carb. Got me about 5% more horses.

Well.. the Jardine is much more open than the stock exhaust.. so the exhaust will be open. The intake is already pretty wide open on the Buell... and the fuel injection will auto compensate for the change of airflow (instigated by the Jardine Pipe). So... after all is said and done changing the pipe is like jetting the Buell... no? I should get an increase in power correct?

... ... not to mention is should sound MUCH more like a Harley!

Thanks

ohhhh my... think I created a monster! and i couldnt possibly be smiling any wider because of it :)

Just took the Buell for a test drive... omg the sound is incredible... very deep rumble and very loud when you get some. Feel like I'm riding my Sportster that had the Vance and Hines pipes on it... but the Buell sounds much deeper... meaner... angrier... more solid.

Before I put the pipe on I ran to the local Harly dealer to pick up some oil (yeah... you have to take off the oil line to remove the stock pipe)... so while i was there I asked if the bike would need remapped or if any additional work should be done due to installing the Jardine.

The customer "specialist" back in service didn't have a clue. She told me that I would have to bring it in to get a different air filter, remapped, etc etc... $150+ labor. By luck an actual mechanic... a tech... came out to grab something so I asked him.

He said that the bike will be fine with "zero" additional work! No remapping required... the fuel injection brain will auto compensate. Said it might take a few miles for everything to adjust but the bike will be fine and that the Jardine slip-on is a great add-on... that is sounds amazing\mean. He couldn't have been anymore correct :)

My test drive was fine except for a miss here and there and some popping when de-accelerating. But nothing like a real deal backfire. Can't wait to get back on it tomorrow!

Removing the stock pipe was a beast! real pain in the... well... rear. Putting on the Jardine itself was a piece of cake... real nice setup. Bike prob dropped no less than 20 lbs replacing the stock pipe.

pics soon... gotta put on the headlight grill and front faring tomorrow.
 
Hey Hobbit.. thanks, as always, for the chimes.

In regards to the cable that runs from the top of the air box to the stock pipe valve (which isn't there anymore)... For now I have the dangling end ,that went to the pipe, zip strapped to keep it out of the way. I was going to run the bike a bit more and see how things go. If all goes well I was just going to snip the cable midway... leaving it on the airbox and removing the other half.

Think this would be ok?

The directions that came with the Jardine state that it could be left on (hidden somewhere) or removed.
 
one more questions for you Hobbit... what does that cable do?

I am guessing as the bike warms up or as various degrees of power are required the airbox valve will rotate to effect the valve within the exhaust... which would then increase or decrease back pressure as needed... ?

Soooooo having it disconnected (valve no longer present in exhaust) will have no adverse effects on the bike's performance I am guessing?

Seems weird that you could simply do away with something like that... you know?
 
hmmmm... so no valve= more power and more noise... all the time :)

So not having this valve on the bike will not hurt anything mechanically? Hope not... cause ummm.. I don't have this valve on the Jardine

I looked thru the Jardine and it is nothing but a straight pipe with some baffling along the walls.... nice :) You can look straight thru it like a paper towel roll.
 
thanks so much Hobbit.. I appreciate your sharing the knowledge.

I was putsying with that cable to try to hide it... I was worrying about kinking it which wouldn't let the valve on the airbox move freely... not sure if thats important or not but.. I felt like it should be able to move if it wants to.

So.. given your feedback coupled with the directions that accompanied the Jardine stating that the cable could be removed... I removed it completely. I am not a big fan of clutter so if it doesn't need to be there... delete it.. hah.

btw... I dont think I'm going on a limb by saying that I betcha I removed at least 30 lbs of weight taking that stock pipe off... that thing is a hog... and huge.

I think the bike has a bit more angry power... but that could just be in my head given the new ferocious sound.

funny... I thought of getting rid of the Buell to jump back on one of those new Irons... or a Nightster... for the same reasons you stated... its just to fun and EASY to ride like a loon. As ironic as it might sound though I feel much safer on the streets having this kind of power and handling. As you said months ago... you think it... you're there on these Buells.
 
Bikes all done... ready to ride! Gonna go enjoy some of this gorgeous TX weather we're having today.

Congrats on the brand spankin new Fat Bob Hobbit! Noticed you got yourself an '09 and are having fun paying the Harley Tax on it :)
 
Holy!!! Well Hobbit... I guess you are paying some hefty Harley Tax then!... and luvin' every minute of it :)

Hey Hobbit... my bike has quite the series of backfires to it yet... not the ear shattering type as if a bazooka went off or anything just... well... when gearing down and such it will definitely pop. It actually sounds nice, and I think my Sporty sounded like this with the Vance and Hines Pipes sooo..? Anyway... you think thats normal with the Jardine or is the bike still compensating for the new pipe and the pop will eventually go away? I have about 150~ish miles on it with the new pipe... its running great... just the poppin is bothering me tad.

thanks in advance for you help!
 
hah... yes you do miss it :)

Mine sounds exactly like the second clip... got that same pop I'm talking about. It does sound really cool it's just intermittently there will be a rather loud pop mixed with the more regular popping. Guess the thing, as you say, is getting used to the pipe.

thanks once again!
 
the adaptive fuel value on the buell has a specific need to learn buy, its between about 35 and 50 mph between 2500 and 3500rpm on a very constant throttle ie no movement, if you follow this for about a mile it will start to learn a new fuel value to adjust the injection n richen the mixture. if you can meet this it will learn a new fuel value very quickly, like a modern car. the aftermarket mufflers dont really add any power they just shift it around so it will feel stronger up top but will lose some bottom end or a bit of torque something u dont really want on the buell, but all round they r a good cost effective bit extra to have fun with.
