Stock 2007 heritage want to put pipes on. what needs to be done so it won' t damage the engine?


Put the pipes on the engine and then take it to a performance oriented shop that has a dynometer and an exhaust gas analyzer. Have them run the bike up and check the fuel mixture at all RPM ranges. If the mixture needs to be adjusted, they'll know what to do. That's the only thing that should need to be checked.

Good Luck

I took off the factory mufflers on my suzuki m50 that is fuel injected and put straight pipe on it. Drove it for awhile and now it wont run unless the air cleaner is off. How can I adjust it?


There is no adjustment on the fuel injection model unless you put it on a computer and have it remapped.

When you put straight pipes on the bike, you did away with a baffle that was in your stock pipes.
so now there is no back pressure, and your bike is breathing now.
But it can't breath if it can't get the air.
When you remove the air cleaner it breaths.
So you need to purchase a High-Flow air filter.
If you have an airbox, you may need to eliminate that as well, but start with just the high flow fliter first.
When putting on straight pipes and a high flow air filter , you will also need to increase your carburetor main jet size at least 1-2 numbers:example:stock 120 go to 122.
if you don't increase the main jet your bike will run lean and hot.

Once done you'll be able to crack that throttle and the whole neigborhood will here ya.
Loud pipes save lives.

I would like my vtx 1300 to be a little louder. can i drill a small hole in the back of the muffler to make it louder will this work any pros or cons please


Honda mufflers typically have several baffle walls You may need a drill 14 or more inches in length to punch through enough of these walls to make a noticeable difference. Changing the back pressure of the exhaust will also lean the mixture. This may cause a bad hesitation on take off. This will happen if you change the exhaust system also. To correct the hesitation you may need to install a jet kit on a carburetor model (about $100) or install a Power Commander on a fuel injected model (about $400 plus programming). In both cases your fuel economy will go down. Your stock system has a five year warranty, should not blue like an aftermarket pipe (unless you leave the choke on too long), and have a good long service life. Unfortunately there is no easy solution for your problem. Any aftermarket system will be way to loud (especially on the freeway) and drilling may not give you the desired sound you are looking for leaving you angry and frustrated. Consider a different option, One of the best sound options I have heard was a set of stock Harley pipes adapted to a Yamaha Virago 1100. Most Harley riders change out there exhaust systems before they even ride there bikes which should offer a cheap high quality system that can be adapted to your stock headers with common automotive adapter pipes and custom build it yourself supports (a simple modification of your stock pipe support/mounts). By not damaging your stock system you can always put it back on if you do not get the desired effect.

If you have changed the air cleaner intake in any way , or the exhaust system in any way , you probably need to put a Power Commander on the cycle. If you have a Power Commander on the already, you need to hook your motorcycle back up to your computer and try a different map for your CDI box. Fuel injected motorcycles are very precisely made. They do not have the ability to compensate for changes you make to the intake and exhaust. By adding a Power Commander, You get the ability to change the fuel injection/power curve to match the changes made to the stock set up. To fix your bike you have to either put your bike back to stock ,or add (or remap) the Power Commander. If your bike is stock and giving you these issues, take it back to the dealer and have the fuel injection system checked out.

Aftermarket pipes bored out, bike hesitates on take off?


Its a matter of preference. You could put the stock pipes back on and have the bike work as it was designed to work.
If you leave the free flowing pipes on, then to complete the package you need to give more air/fuel and step up the timing curve.First it needs to take in more fuel to allow for the better respiration. Second you need to let the ignition take advantage of the new found fueling. If you set up the motor correctly with a better breathing intake and exhaust and utilize the ignition to take advantage of it then your motor will give you better response, more power and more efficiency ( better mileage/ MPG). In short it is one of the cheapest and most dependable performance upgrades ( best bang for the buck) you can make... if done correctly.

im sure the valves and compression are good. as for changing pipes, the computer will adjust for it to a certain point. bringing everything back to stock will probably increase your power. if you want to keep the pipes and fuel pack, i would buy an after market ignition module as well

If you want the bike to run at top condition YES it is the only way with out putting on even more expensive fuel injectors. Power commanders are made for all bikes, anyone that ever changes there pipes from stock to any aftermarket pipe should buy a power commander and retune bike, plusyou will get all the advertised horsepower from the pipes and increase fuel performance from it. Power commanders are fairly cheap compared toooo you burning out fuel system because it runs to rich or clog it by runig to lean....go with power commander and in about 4 hours it will run great ( thats install and retune time)

Exhaust


I am very pleased with my modifications on my Road King Classic, and to tell you the truth, I have "invested" the months, almost the years, in order to get perfect combination (from my point of view). So, here is my recommendation: 1. Stock pipes 2. Wild Pig Pipes/mufflers/slip ons (1 3/4" baffles - not too loud, 2" baffles - quite loud) 3. Screamin' Eagle Stage One Kit (read as: more air) 4. DFO (Digital Fuel Optimizer) to adjust everything, to "help" all new parts to work in harmony. Adjustment will be done via producer's web site, in co-operation with very kind people from Dobeck Performance Forum. Also, I have to emphasize that I did everything taking into account affordable prices. Hope this helps.
