X-flow on Yamaha R1 carbs

[freddy686868]

I have R1's in my standard 2ltr pinto and the jets are 1.8 so 1.6 for your engine sounds about right. The best and only thing to do is get them set up properly on a dyno (or rolling road as you guys call it).

People who have issues with bike carbs are 99% because they tuned them themselves or are not using a fuel pump from the same bike the carbs came from.

Good luck

we are using a facet solid state fuel pump and have had no issues but we use a very small swirl pot to hold the fuel above the carbs and the rest is returned to the tank, so the pressure of the pump is 4-5.5psi but most of the rpressure goes back to the tank straight away.

I have just heard of more than a few issues with incorrect fuel pressure etc..

If yours works for you that's awesome.

Cheers,

yeah as you say it is people trying to do it at home on the botch without a pros help, bogg bors and a rolling road setion.

[Matt75]

Correct, and then they bag out bike carbs. Same goes for most things though...

[n20mrp]

Won't let me upload, but under the main trumpet there are three holes/jets. Which is air correction
Left has a removable jet brass, upper is very small looks to be plugged and right has a brass insert with a very small hole
