Scavange (spell check) gas easier/more freely so it draws in more fuel?
If itÂ´s really rich now and you donÂ´t have a K&N filter you can probably get a few ponies more....and open up the airbox

Tubes are 20 quid each mate, Yamaha or factory pro. I would be amazed if yours weren't showing signs of wear. Mine were at 16K. Symptoms are very jerky, on-off throttle from closed & poor mpg.

I think steves right just coincidence if im true it was a little hesitant from closed throttle before bafflectomy

I've heard rumour that they can wear as early as 5,000kms.
I had mine done 2 or 3 years ago and replaced with Factory Pro and I'm sure mine are worn again at 72,000kms. Might try Dynojets next.

factory pro ones should last longer because they are nickle plated

I just changed the tubes & nothing else. Can't see the needles wearing out on standard brass tubes. They say to change float bowl gaskets but if they're not damaged ???

anyone have a part number for emulsion tubes?

No part number sorry but you might find this thread useful when you replace them.

The needle jets or emulsion tubes aren't easy to identify from the parts list either.
