I need some help with making the change over to true duals, I have a stock 05 FLHT with aftermarket slip-ons, I was thinking of adding some true-duals but was wondering if a bunch of crap needs to be done to the carb just to add the duals???
I really just want simple to let the front and back cylinders to blow out the gasses more evenly to release back-pressure some along with a small bit of engine heat...I was going to also install them myself to stay away from the STEALER....If anyone has any info to help me decide......please by all means tell me....I just don't want the duals to turn out to be more trouble than it might be worth.....Thanks all.......

 

yes, you'll have to tune the carbs for the change in the exhaust.

Also, realize that by reducing the back pressure, you will give up some torque. This in turn will impact the power of the bike on when you start out from a stop light.

As someone who has gone to TD's, I don't notice it much, but some people here on the forum feel it's a huge deal and won't ever go to them unless they have bored out the motor.

I don't know that I would consider going to TD's a pain. A lot of people have done it. So it's not like you have to do a lot to figure out what changes need to be made for tuning the carbs. I'm sure there are kits with complete directions for doing this sort of thing out at very low cost.

 

I didn’t notice much lose of torque but a huge lose in heat. My 06 with true duals has less heat on the rider then the 09 I rode with the new under frame rear cylinder exhaust.

 

If you have stage 1 breather kit and bike was rejeted properly, All I had to do is add alittle fuel with the air fuel mixture screw. Duals lean your bike out a touch.

 

I have a SG with motor work and went to true duals. Less heat and a lot more noise, really hard to get more hp and torque. Just went to Rinehart 2 into 1 and never going back. The power is great, good HD sound. I would stay with slip-ons unless you have extra money you want to spend.

 

Thanks for all the info everyone.....I think I am going to stay with the slip-on's and spend the $ on something else.....Like maybe a nice, easy (install) new stereo for the FLHT.....Any ideas on a stereo that is good lemme know....Thanks again everyone...

 

If all you do is add true duals you should not have to re-jet your carb. There won't be much increase in power but it will be louder. Contrary to popular belief you don't lose power with true duals (another old wives tale). If you want to get everything you can out of the stock motor change the air filter, add an adjustable ignition, and re-jet the carb. It'll really make you smile the next time you twist the throttle.

 

Maybe a little of the subject, but I have a 2006 Road King Custom with Rinehart True Duals. Love them, but how do you guys tighten the most inner nut to connect the pipe to the head.

Special Tool?

 

I used a swival and an extension on my torque wrench.

 

I used a smaller socket set.. One that had thinner walls that I could get on the nut.
