Bought a Lexx Exhaust. Installed and now the bike is backfiring or popping like 2 milliseconds after letting off throttle.
I put stock exhaust back on and all seems fine. No popping or back firing.
It seems I need to figure out if this is considered back firing or popping as the issues for each are separate and the trouble shooting is a bit different?
I am thinking it is an issue with a leak in the header possibly? Or is the bike running rich now? Adjusting the idle RPM screw doesn't seem to help anything.
Stock bike with crank case delete and emissions block off delete. Air box is not opened up and has stock jetting. Checked air filter and it is on with a very good seal. Checked air box to carb connection and it is a also a good seal. The exhaust has the spark arrestor installed.
When I installed the exhaust I never put the clamp on that clamps the header and exhaust piece together that is utilized on the stock header/exhuast. The exhaust piece is different and smaller and sit further back but appeared a good enough seal.
Video of the problem below.
Some help from fellow Honda X owners is muchly appreciated. I really want to ride with this new exhaust but not if I have issues like this.
