2009 nytro mcx 240 upgrading to 270 questions

[topdog]

Looking for information on upgrading a mcx 240 nytro to 270hp
anyone have pictures or source to locate the plumbing/ routing etc. Tried searching forums and mcx website w no luck.
I just sent my mcx ecu to Prince George Yamaha for 270 remap.
I have a high flow external spare pump from my past mcx 310 apex
I will have to pick up a fuel regulator still.
Apreciate any info, thanks

think you have it nailed pretty close. Flash, fuel reg, and pump. You also have to adjust your wastegate and possibly some clutching depending on what you have.

Finally found a diagram on configuration. Would anyone know the malpassi fuel regulater part # or where I could get one? Thanks!

A tunnel dump exhaust would be good if you don't already have it.

Are you leaving the stock fuel pump in the tank and adding a second or deleting the stocker? My Powderlites/Boost it setup deletes the stock one. It runs great but occasionally vapour locks and we need to take a time out. I'm not sure if running both pumps would help or even if it's a good idea.
