My son has a 1994 sl650 and has problems with it bogging down and he says it takes forever to plane out. I noticed the rear cylinder spark plug is not discolored at all (but it's wet) and the other two are normal. The rear carb also sprays a mist upwards when you hit the throttle. I'm open for any suggestions.....

Re: Need help!
I would check the reed valves sounds like one may have a crack, pull the intake off and inspect them -
Re: Need help!
Thanks jbfinn for the info, but are you talking about the diaphragm asm. when you refer to the reed valve?Comment

Re: Need help!
The reed valves are between the intake manifold and the case. You have at least one bad one - replace them all. You need to remove the carbs and intake manifold.SBT Tech Support is here to help with your problems.

Re: Need help!
are you sure the back carb is good? My center carb was bad (stiff diaphragms) and I had a wet (blue oily) plug.Comment
