MM 600 Jetting Question

[jweyand]

Can anyone help me out with some suggestions to jet my '97 MM600? The local dealer says i can buy a jet from him but i need to know exactly what i want and that he won't suggest anything since i'm not paying him the $85/hr to install it. The sled came from MN and runs ok but you can still feel it bogging down. If you back off the throttle and hold it steady for a little while the bogging kind of burns itself out and runs full capacity again.. Jetting it should help right? i live at 9000ft so it's run up to 12000ft.

That should have the smart carbs on it. If it is still stock you will have about 160 mains in there. You could try 150 or even 145 and drop the needle 1/2 if everything is still stock as far as pipes and air box etc...and read your plugs and piston for the right spot.
I have the same sled and I ended up getting some standard carbs. I had nothing but problems with those smart carbs. Some guys have luck with them but I didn't.

Thanks for the tips, it is a smart carb and everything is stock so i'll try a 150 and see what happens.. thanks again

Tell your dealer to K.Y.A. Shame on him for not suggesting the correct jets to you.
They did not used to be such bad people. Must have changed a lot with new owners.
There is a dealer in Cheyenne WY, seams to be a good guy. You might give them a call for help.
