I emailed them a couple years ago about he 2 into 1, and they said "no rejet necessary".....that said I just looked at the RHB site and there is absolutely no mention of (it was a selling point at the time - that rejetting was unnecessary) rejetting at all yeah or nay.......also when you put in your order for a set of pipes they show a jet kit as a suggested item......so I am thinking they are not promoting or not endorsing the "no need to rejet" philosophy anymore.rixemailfl said:Correct me if I'm wrong...
He's talking about the Roadhouse 2 into 1 system. Not just slip ons.
If he's replacing the whole system, especially with a 2 into 1 setup, he will definitely need to rejet. The 2 to 1 setups do a MUCH better job of scavenging exhaust from the cylinders!
If he was only doing slip ons he could get by without the rejet.
The air screw adjustments only affect the idle circuit. You can adjust that correctly for the new pipes, but it's the Mid-range (new tapered needle)jet and main jet that will burn a bike up if running too lean for too long....might run great though....so don't be fooled by how it runs. Some bikes running lean enough to do damage run like scalded cats.carolina sabre said:I've been told that rejetting is for performance purposes on most bikes. you can make your bike run fine by adjusting the air/ gas mixture. If this is true then I will NOT rejet when I put my HK's on I just ordered. My bike gets me from 0 to oh [email protected]% fast enough right now. Having said that, If I put my pipes on and I can't get it to run right with the screw adjustments.... well then I will rejet.
If the exhaust system you put on has less backpressure than stock, you should rejet.carolina sabre said:I've been told that rejetting is for performance purposes on most bikes. you can make your bike run fine by adjusting the air/ gas mixture.
