Where are the idle mixture screws on a 82 Maxim 750 and how do you lean it in or out Thanks?
On these carbs the adjustment screws are located on the top of the carbs, towards the front of the bike if they are still on. They are right behind where the choke goes into the body. On some models of this carb they plugged the holes for the adjustment screws with a little plug of aluminum. If they are plugged, drill a small hole into the center of the plug (very carefully of course) and screw in a small screws that bites well into the hole. Then take a hammer or pliers and pull on the screw until the plug pops out.... Now you should see your screws... beware on a bike this old these screws may be seized and if they are at all don't force them. The screws are brass and break easily. If they break or get stuck fully closed the carb is trash. Believe me on this, I have ruined a set before! The tighter you turn the screws, the leaner your mixture. Also, let it be know that you bike uses a second form of carburation through what is call the Yamaha Induction Control System YICS as is printed all over your bike. This YICS system is basically a chamber on the engine body that mixes all the mixtures of the four carbs together before going into the engine... the purpose is for consistent fuel mixture to all for cylinders and thus better fuel efficiency and smoother performance. All this is great, but it makes individually tuning the carbs almost impossible without plugging off the chamber with a YICS tool. You can still by these online or you can find some neat links to make one. After you plug off the chamber, hooks some vaccuum gauges up to your vaccuum nipples on your inake boots and then tune away... just go for consistency. Good Luck!
