View Full Version : Adjusting the fuel pressure
06-15-2003, 07:01 AM
I was wondering if there is any other way to measure and adjust the fuel pressure in our bikes besides using the evoluzione products.
If there is an alternative way does it differ between earlier models ('99-like mine) and newer ones???

Dont think so dude. All the mille-s use the sam fuel press regulator, and then ya got to cut and modify with Kens deal. Ists an easy an inexpensive process though.

Hi Mille Ryan
I know that evoluzione's product is what I need but when reading the fitting instructions I realized that I need to drill a hole on the bottom of the air box...is this the case???

ya you gotta drill the hole, but u can also seal up around it easily if it s a concern. It comes with a plug cap to put over the hole but mine came out and I lost it :eek: Been running mine for onevr 2 years now, works great.

My only problem is that I have replaced the original air kit with the carbon one made by Renegade. I have no problem drilling a hole in the carbon plate but it can be really tricky!
Anyway thank you for your advice...I will probably give it a go.

the reason for cutting the hole in the air box is to allow easier adjustment - otherwise you just remove the air box to make adjustments.

I thought that the hole was drilled in order to keep the fuel pressure modifier in place...I am a little bit confused now!
Why do I need to remove the airbox in order to adjust the fuel pressure???

the adjustment screw is on top of the regulator. once you initially set it, you may not need to readjust but if you do, the airbox would be in the way.

Thanks for the advice Ken,
I am planning to fit the 54 TB's package and I need to know all the details before I go through with this mod. I knoiw that I will have to check the fuel pressure and probably adjust it...
I have heard that the optimal pressure will have to be 48psi...correct???
By the way what to expect (performance wise...)???
