I have an 03 grizz,the problem is that it wont run properly.It idles fine but if i go from idle to full throttle it stalls out.But if i slowly bring the revs up it works fine.Any ideas?

 

It could be a number of things. I used to leave my gas on and ended up having a corroded needle. It acted in a similar fashen as you stated and got where it wouldn't even run. I would leave the gas on through the week and ride on weekends. I turn it off now and have had no further probs.

 

Ya sounds like a carb problem, might need to throw on a new spark plug, clean out the carb change fuel filter and get some fresh go juice in there.

 

i checked the carb,everythings clean and ajusted properly.i changed the spark plug.its in the shop right now and the mechanic called me and said the carb is fine, hes thinks it might be electrical.He dosent get it and i dont get it im stumped.

 

This motor doesnt have a tps, so im wondering why he thinks its electrical. The computer on the grizzz has no idea about thottle position, im stumped as to why he thinks it electrical too.

Sounds to me, like the air lid is off, or some other reason for big leanness, or the main jet is partially blocked, or the diaphram on the carb is ripped, or intalled pinched.

Let us know what he finds.
