Intake and Exhaust on stock trike

[Casper]

I have a 17 and will de cat the header for heat issues, not performance.

i also have a Big Sucker cleaner for later down the road. When that time comes I’ll install the BS air cleaner, mufflers and a tuner.

I would like to see this in writing just because

The Screaming Eagle catalog is pretty specific about air cleaner and exhaust

You must recalibrate the ECM when installing this kit. Failure to properly recalibrate the ECM can result in severe engine damage. (00399b) This is published by HD

I dunno how far they are going to push this since the EPA spanked them pretty hard along with tuners going outside the EPA JMO

What Jack said !

I spoke to a dealer yesterday about changing just the air cleaner assembly (keeping the stock air filter element) to get rid of the big piece of plastic. His explanation was that it can be done without doing any tuning or changing the tuner. He added that there should not be any warranty issues unless the problem came back to that specific part. He said that the Motor CO say what they say is because they want people to do a complete Stage I, not just mufflers or air cleaner assembly. He said that they have had several change out their air cleaner assembly without any issues, but they also prefer the complete Stage I so they stay in line with the mother ship.

I know too that there can be a big difference in money laid out depending on what you do.

I too am staying with stock on my 2017 TGU. The stock pipes are really fairly loud and the engine seems to run great with the stock air cleaner and stock pipes. I did however add the DK Custom Lift Kit and the DK floor board extenders which I consider MUST HAVE items. If I were frequently riding it two up, I would ditch the air shocks in favor of shocks that DK Customs sells. However, with rear tire pressures at about 21lbs, front tire pressure at 38 pounds and air shocks at about 15 pounds, my ride is quite pleasant.

You must not ride Hellinois roads
