Yeah, I've come across a lot of videos where people show what they've done. However, it was a challenge to find someone actually performing the act from start to finish. Thank you. The second video posted makes the pipes sound real nice. However, that's a bit much for me to do personally.

@Summer: I've got a bi-metal hole saw. That should be good, right?

 

[sh3r0y]

I did the hole saw mod on my '03. Took like 10 minutes. There are 2 layers of metal you have to saw through and the second one is about 1/4" further in than the first.

Did you rejet after?

I just bought my 1100 and it came with an extra set of stock pipes. Think I will be experimenting on those soon. I had a coworker that doesn't own a bike comment yesterday about how quiet my bike was.

I agree with all who told you to deal with the tires above all else!!!

As for the air intake: In my opinion the Hypercharger adds some cosmetic appeal, but does little to nothing in terms of performance. Rejetting will be dependent upon the pipes you choose. If you're looking for improved performance, PODs is the way to go.

As for pipes: I spent countless hours of study comparing sound clips, listening to actual pipes on bikes in real time, and discussing them with other riders. I was looking for a deep throaty rumble rather than something that resembled a screaming chain saw or weed wacker. I went with the Samson Ripsaws with standard baffles and was not disappointed.

Let's face it: Modifications are a matter of personal preference. I know guys who have thrown thousands of dollars worth of stuff at their bikes in search of that allusive outcome they seek. Their garages are full of stuff that didn't produce the outcome they were seeking. Others have done their homework prior to purchasing and installing aftermarket products, and are pleased with the outcomes of their choices.

Finally, a closing comment, just a thought to consider: We're talking about an 1100 here. It's nice to try to wring every watt of power that you can out of the machine, but it does have finite limitations due to its size. If one is planning substantial expenditures to improve performance, it might be prudent to simply upgrade to a larger bike.

Agreed. Tires have been ordered and will be getting replaced in a week or two. I still haven't taken the bike out of hibernation. The weather in Canada just blows!

I too have spent quite a bit of my time listening to pipes, etc. I guess I was comparing this to the awesome explosive sounds my Harley 883 Sportster with Screaming Eagle pipes used to make. Sigh. I too have been told on many an occasion that it's "nice and quiet".. UGH!

I think i'm going to just drill out the baffles and suck it up on this one the cheaper route. What's the worse that could happen

I have ordered a new K&N filter for it though. That should be a good replacement to my paper crap and wake the bike up a bit.

My plan is to move up to a larger bike in the next 3/4 years anyways.

I have time this tuesday to do this so i'll document it properly and make a video for everyone to see.

Wish moi luck !!

When I did the exhaust mod I also modified the stock air box http://www.altsale.com/airmod.htm At that time I rejetted also. Surprised you have not been out yet. Down here in the banana belt of Ontario I've been out riding for 3 weeks. If you have questions on either sent me a PM.

 

[sh3r0y]

Sorry, should have explained why. My bike was out getting painted and a friend and I are going to put it back together this weekend. Plus, my front tire was ordered from the States with someone bringing it for me. I didn't want to go out without getting it changed. I'll go for short rides next week though. Very excited.

 

[Sick Mick]

Michael pretty much hit the nail on the head. Just one last note...keep in mind that any modifications you make, you will never recoup the money back out of them when you go to sell.....at best you'll get maybe 25% of what you paid.

But....if like me, you like to change things often.....the 1100 is a perfect bike to choose because you can find everything used and pretty cheap. I generally change the total look of my bike every year...so it's really not a matter of things not working out....it's a matter of being bored with the look and wanting a change without having to drop another $5000+ on another used bike.

In the last 6-7 years, the look of motorcycles has changed from the ugly fat rear tire drag stretched look...to the old school hard tail skinny tire lane splitter...and all points in between. It's nice to be able to keep up a bit on the different looks.

before another "did you re-jet" question..

ANY TIME You increase air either going in, OR leaving the engine, you WILL have to Re-Jet to have a properly running bike! The bike is set from the factory to have a restrictive intake, and an equally restrictive exhaust and is jetted accordingly. Once you start changing these in and out values, you need to adjust fuel in to make the bike run correctly. Will it run without being re-jetted? Sure, but you will be running lean, burning plugs, heating up the engine un-necessarliy and popping and back firing.

 

[nick57]

i have a question if you only add performance pipes should you rejet to larger mains.because mains only come on at half to wot.and how often do people go that fast

 

[SThomas]

mains only come on at half to wot.and how often do people go that fast

This confuses me on many levels.

I do often send my 1100 through the throttle range just to be reminded its still alive! Arent we above half throttle on the freeway?
That said, you also need to tune for start up and idle. Bikes running too rich dont like to be started when warm, bikes running too lean dont like to be started when cold

 

[nick57]

i think were only between quarter and half.i dont know maybe im wrong if when passing we go to wot we need the extra fuel to run smooth

i have the idea that if you dont increase the amount of air going in you dont have to rejet

Jetting is a function of the balance between air-in and exhaust pressure out. If you keep air-in constant but reduce exhaust pressure out, you have upset that balance and should rejet.

Your comment brings to mind this fellow with whom I ride who has quite an inventory of slightly used pipes in his garage. He was never happy with the sound that his bike made inspite of all the money he threw at it in the form of new pipes. I finally figured out that he was trying to make his bike sound like a Harley. I then suggested in jest that if this was his desired outcome, why not simply buy a Harley. Next thing I knew, he had a Harley Road King with Screamin' Eagle pipes on it. Hope he's happy.

On a related note: My ideal has always been a Liner, but I never could bring myself to take the plunge. I've put considerable time, effort, and money into personalizing my 1100 to get it just the way I want it. Now this spring my dealer offered me what I consider to be a fantastic deal on a trade up to a Liner. After some tedious and painful consideration and discussions with my wife, I've come to the conclusion that I'll stay with the 1100. It would cost me thousands to personalize the Liner to my satisfaction, and at the age of 70+ and being of relatively feeble health, how much enjoyment of it do I realistically have left in me?

Apologies for the hijack.

Absolutely! think of your intake/exhaust system as a straw. If there is a kink in the straw, it's going to slow down the air moving through no matter if it's at the front or the back as you blow through it. Put a hole in the straw in the right place and you'll draw in air along with fluid. Your bike is just like that straw. It's just a big air pump. It runs on air...like 14:1 to fuel. The game is to have all those holes exactly the right size to hit that ratio.

On any bike there are 3 major points of restriction, the intake, valves and exhaust. Changing any of those restrictions will change that ratio. That's why we adjust the carb to accomodate the new changes. Any change will effect that ratio, even external things like elevation and humidity have their effects.

We are fortunate to have these things all figured out on the 1100 with hundreds of documented test runs and experiments. It's also important to know that if you really want your bike to be tuned properly, you'll need to go find the nearest dyno and do some runs to see where you are at. There is no other way to be "right on" due to all the environmental changes. But...you can usually get it darn close with the proven jetting charts out there.

IMO, if you don't think you can handle tuning your carbs after every change you make......you probably should be letting somebody else do it all for you. There is absolutely nothing wrong with that.

Difficult to post after Sick Mick's advice, I've referenced his posts in several mods I've made to my bikes. I had Dunlop 880's on a 1300 V Star Tourer, they were good tires, good cornering capabilities so I felt secure on them.

For the mods I made to a 2007 V Star 1100, I installed Cobra 2-into-1 exhaust and upgraded the intake to K&N high performance filters, and rejetted at the same time. The performance change was significant, and I was very pleased with the sound when competing with cage vehicles on the freeway.
