Does a 4 into 1 pipe sound better?

[Coopz]

The current pipe on my bike is a custom, I think I know who made it so I'm hoping he hasn't retired yet as I'd love him to fabricate one for the other side (I have a 4-2 collector).

[MickyJB]

Mine has the FE Yoshimura muffler, I like the sound, subdued unless your revving it out and then it sounds sweet 😁

Micky, tri oval on yours👍End baffle out, so nice.

What part of 'I Like' didn't you understand?   

If I want noise I ride the XJR1300 .. twin Delklevics makes it sound angry.  😁😁

If you can tell the difference between a 4 into 1 and a 4 into 2, you're not going fast enough!

[grog]

Micky, very crap answer. Ill ignore it this time.

[MickyJB]

So you didn't get my sense of humour ...    :frustrated

I had a 2001 red/black Xjr SP with dual Remus pipes, it sounded awesome but man that thing drank fuel...

My XJR consistently gets better fuel economy than my GSX1400. I think the Suzi is running a bit rich ... what's the go to fix for that.  ??

Well, apart from the obvious plugs & air cleaner, the oil temp sensor.  If the sensor is sending erroneous messages to the ecu saying the oil is still cold / cool, the ecu runs a richer starting / warm up mixture.   Could be that, there have been a few gone bad & reported on here.   

What sort of usage are you getting? Standard running 14 will give anywhere between 6.7L/100k to 5.5L/100k  depends on yer wrist action . . .

Mid to low 6's .. if you look at the screenshot the figure of 9 was a fill up after doing the tank breather hole mod.

New plugs and air filter, Oil & Filter due in another 2000k. Bikes goes superbly, and I don't know much about fuel injection whether fuel amount can be adjusted 🤷�♂️

I think only the later models are normally flashed and remapped on the ECU, but as the 14's ECU is quite basic it's not that common.  I'm not a huge fan of PowerCommanders as they only do basic fueling, but I have one on my 14 that was mapped on a dyno with a full system and can't fault it.  It pulls smooth and strong across a very wide range and isn't awful on fuel.

Sumting Wong.. My XJ was the carby version and it averages a thirsty 10 litres per 100k. I had to constantly flick the petcock to reserve at 180k range. I get around 300k+ out of a 1400 fill-up.

My XJR is 2002 and carby also. Consistently in the mid 5's and it's not ridden slow

Fuel injection can be adjusted on all years. Equipment and methods vary.

Before adjusting the EFI-controller many other things should be considered, checked, and necessary/desired action taken. Makes no sense to fiddle with the controller when something is amiss.

There are a great many things affecting fuel consumption. First is how you ride. I have done as little as 5.1 liter on a leisurely long ride and over 8 liter on madness runs. Riding short distances increases consumption. The colder the weather the higher, the warmer the lower.

Fuel quality is another one. Got ethanol in it? The more of it the higher the consumption.

4.64 vs. 9.19 liter on consecutive days  What was different? Maybe your fingers slipped when entering the values? Filled tank at very different levels? Never seen values like that before.
