Tuner exhausted replace tuner - Samsung SCX-4300 Monochrome Laser Multifunction Printer

I think replacing the exhaust will help, but it's an air cooled engine - they get fricking HOT! It's a very common issue with Harleys -just as it was with VWs back in the day. Replacing the exhaust will not void the warranty but it's not going to make a noticable difference - it may drop the temp a few degrees, but hot is hot. Your dealer might try to pull that "warranty is void" ****, but don't cave in - they are bluffing. They cannot void the warranty for this. Everyone changes their exhaust. If they persist, contact customer satisfaction and choose a different dealer.

You might look into putting a parade fan on - the bigger, the better. There are several to choose from and they help a great deal.

Also - Kuryakyn makes lexan heat shields which do help.

That is probably because the backup battery is exhausted and flat.
It won't cost much to replace and is usually situated on the tuner panel or near the uProcessor.
Hope that helps.

Take it to another dealer. Dealers usually will not warranty any type of performance work. I find it difficult to see why the exhaust would cause the vibration. Just make sure the exhaust is supported properly to the frame. I would however suspect the race tuner. If the tuner is not adjusted correctly it will cause the engine to run poorly. It may even cause the engine to overheat. I'd suspect the igniton timing. Take it to another dealer or to an aftermarket that has a "good dyno man".

Now, there are two types of dyno-tunes. One, is actually not a dyno tune but more of a dyno run up. Regrettfully, this is what most dealers do. They install a bunch of stuff and then put your bike on the dyno, run it up, and get a print out of the horsepower and torque, that's it. This is simply a run up. The charge us usually about $35 - $50 or so.

Now a true dyno tune is totally different. The run up is just the beginning to establish a baseline. Then changes are made to your race tuner, intake, fuel map, timing settings, and exhaust to get the highest horsepower and torque out of your bike. You are usually charged "X" amount of dollars to begin with and then some much per hour. I've seen a good dyno man work on a bike for several hours changing jetting and such on the bikes and believe me, if the guy does what he's supposed to do, you can feel the difference. Bad part is a "good dyno man" is very hard to find.

Good Luck

just get a hd standalone tuner and hook it up to one of the inputs. way cheaper solution.

There is a procedure for your exhaust system. Its called Diesel Particulate Filter (DPF) Regeneration. Your dealer will have to do this for you. The particulate filter is in the exhaust system. It traps large carbon particulates so they don't get out into the air. The system is designed to take care of itself but does need to be done by someone with a tech2 scanner.

You need to get a race tuner for the bike. When you made changes to the pipes you changed the pressure that the ECM was looking for and that's why the bike is backfiring on deceleration. You need to get a race tuner (Harley's Screaming Eagle Race Tuner, Power Commander V). These tuners will allow you to adjust the ECM settings so that you can control the amount of fuel unburned in the cylinders. My suggestion is to go to www.fuelmotousa.com and look at the power commander (since you like to play with your own stuff).
Also take a look at www.hdforums.com which has a wealth of knowledge on the HD.
Good luck!

What year?
but other wise, throw you on aftermarket air intake,
then put ya on some higher flowing exhaust.
A larger cc throttle body maybe.
Get you a tuner.

(intake in exhaust will add a bit of pep plus some MPG'S!!))

whats wrong with the old tuner? did the connector break? depending on the damage the connector can be replaced to replace the tuner right out i would call a medium difficult level. it invovles removeing the signal board the board with the tuner on it simply unsoldering and replacings care should be taken not damage surface mounted components. at the shop it is possible we repair these tuner which involves opening the can tuner and soldering a new connector to the can of the tuner.

Robert,
Replacing the "F" connector is usually all that's needed unless the tuner board is cracked. You could remove the tuner - send it in for repair and re-install it... It would clearly save a few bucks!
Any shop should be able to do that one easy enough... Around here we charge $40.00 including the part to replace the "F" connector and there are shops that charge even less...
