Hello!, I am brand new to this forum and need some help!. I got a used grizz 600 last year and it was bogging when I gave it throttle, and after running a bit would stall out when giving it throttle even after adjusting the choke lever. So I pulled the carb out and thoroughly cleaned it with help from some youtube videos (I've cleaned and rebuilt carbs for other things before like my gensets and yard equipment etc. so have some experience, just never messed with a Mikuni carb as complex as this one before). Now after putting it back in, it fires up great but then it idles quite high and seems to slowly increase in RPM's and never settles back down to a gentle rumble like it did before. I took the seat off and I put my hand over the air intake on the airbox that has the opening right under the gas tank, and when I almost fully cover it with my hand with just a little bit of space between my fingers it then idles down to where it did before where it would allow me to put it into gear etc. Without my hand over the airbox intake it revs right up again!. I am somewhat mechanically inclined but just never messed with a carb like this before and I am not sure what adjustment's I need to make to get the idle back down to where it was before. Do I need to adjust the throttle cable/throttle lever at the handle bars?, or the small screw underneath on the carb (I have it backed out 3 1/2 turns per Yamaha spec)?, or do I need to fiddle with the choke cable?. Not really sure what to do to lower the idle speed. I also matched the specs inside the carb to Yamaha's specs for the main jet etc., so I'm hoping it's something outside that I can easily adjust without having to completely pull the carb out again. I'm sure I could fiddle with it long enough and eventually figure it out, but I figured asking some pro's would save me a ton of hassle!. Any help is VERY much appreciated!.
