yamaha 03 rx1 fuel prob please help

[tntsmallmotor]

I have a 2003 Yamaha rx1. carb has been cleaned 3 times, new plugs, fresh fuel, idles great, but has a bog mid to high rpm..or if u punch it from a idle she bogs... but if u hit choke motor takes off till it floods.. so is fuel problem for sure.. what am I missing... jets are clean...

Fuelpump?
Look @ memranes and clogged or leak on vacuum hose.

is it fine once it gets past that or does it keep bogging the more throttle you give it.

air box not conected properly ???

boots to carbs can look like they are on but cause similar probs, buddies been thru almost everything a RX1 can give ...

reseating all 4 boots isnt easy and is best with 2 guys ...

let us know ...

Have the Carbs been sync'd since the cleaning? They run like **** if the vacuum is off on each carb.
