I have a 2006 Kazuma Falcon 250 that I bought new in 2007. When I'm riding it it takes off alright, but as soon as I open the throttle all the way it bogs down and loses power. I've adjusted the mixture screw which hasn't helped. Any suggestions on what migt be causing this?

 

first take off the gas cap and remove all the metal pieces out of the cap. its for rolloversafty. not needed. plug gets stuck in vent hole and gets no air. try that first
after that it requires a jet changes in the carb.

 

Welcome to the forum imac! [img]i/expressions/face-icon-small-smile.gif[/img]

Full throttle isnt controlled by the mixture screw. Is the air filtert installed correctly. Are you still using the stock Chinese spark plug? Has it done this since you got it?

 

they are from the factory very lean. main jet is a 110 you will need a 125. pilet is a 38 you will need a 42.

 

Yes, it's done this since I bought it. Yes, I'm still using the stock spark plug, but I've seen a couple recommendations to change it to an NGK, which I'm going to do. I'll check the air filter as well. Thanks for the response.

 

Thanks for the advice on the jets and gas cap. This is a great forum.

 

when you first start it Im going to guess it pops and is nonresponsive. and the red light is on most the time showing its going to overheat. with the jet changes yo can start and ride no waiting for it to get warm.

 

If anyone still has that email manual will you please foward it to me. I have a Falcon 250 and need to replace the carb and need to know the correct hose placements. Thanks

 

I dont have an email manual. do you just wnt me to tell you where they go. why are you replacing the carb? chang the plug

 

That would be great. I broke the frame on my atv and had to take apart half the engine to have it welded back. I forgot to label the hoses and such off the carb. Please let me know.
