2003 YAMAHA RAPTOR 660R Carburetor problem

[amelia slabbert]

Hi I have a YAMAHA RAPTOR 660R 2003

I have taken of my Air filter and sprayed in my air inlet some carberator cleaner while starting it. That causes some problems. It struggles to start now. Please look at my attachedment video. 

What can I do now.?

It may be getting too  much air,  running too  lean to  start  .. Try  replacing the air filter  and other stock inlet air components and see it if starts and runs much better. Some quads  need the  air filter installed to  run  properly. Several  members have run into that  problem  before.

Thank you, but if it is not the air filter is there any other errors it also may caused?

As a general rule, spraying carb cleaner through the carb into the engine does no good. The carb cleaner goes directly into the engine without cleaning the passages in the carburator. If you suspect the carb is dirty, you can either remove it and clean or try a gas treatment such as Seafoam or Mechanic in a Bottle.

Thanks I'll try that.

you definitely need the filter and inlet tubes connected, the carburetor needs the vacuum created by the restriction of air from air filter to work properly.
