2006 SJ...Yamaha changed carbs?

[enzo]

My buddy picked up an 06 SJ in December. He just put on a B-pipe and was unable to get it to run clean on top. I asked if he did the included jetting and set the mixture screws correctly. He said he could not find the mixture screws!! So i pulled his hood and sure enough, there are no mixture screws on the 06 carbs! I looked and the casting is there where they should be but its like they just did not drill holes for the screw needles at all. I guess these carbs are 2006 EPA compliant and have no adjustments.
Can he send these carbs off and have them drilled out and modfied? Or is he going to have to buy new carbs?

Thanks

Same problem with the 05's. Those are brass plugs with some black paint over them. I drilled and tapped the plugs then yanked them out with a dent puller. I later sent them to jetskisolutions.com and had the channels cut down, screws extended, and knobs added. You could pick up a set of older 38's for about the same cost w/ no downtime but I like the JSS knobs :biggrin:

crap......just looked at my carbs on my 04 and there are no screws on it either. how is someone suppose to tune these carbs if they dont put mixture adjustment screws on them. almost would seem that they dont want us tampering with these things.

i did a little research and there are suppose to be caps over the adjustment screws. they are a pain to get out since they are brass but the screws are underneath. let us know what happens.

Yeah the 04's, 05's, and 06's have the tamper proof plugs. They were really easy to remove. Mount the carbs on some nails on your work bench, drill, tap, pull. Some folks say they don't even use a dent puller. Pics linked above ^
