Fouling plugs and backfiring. Runs much better at high RPM's. I realize that the problem is likley worn needle jets after reading through forums. I am just looking for a little direction on what to do exactly. I haven't messed with carbs much and am concerned with messing something up. I have a Haynes manual, but still am lost.,Hi, I have a 98 M750 that I have had for 8 years and it has done 110,000Klm (68,000 miles) when it had done about 20,000Klm it was doing the same thing as yours fouling plugs and running rough at low speeds, so I took it to a good dyno tuner and he found the bottom end rich and the top enp end lean, resetted the floats and rejetted all good again. So just find a good dyno tuner. Let me know how it is going after the tune up.,,,

Rough low idle and black smoke


Bad carb or fuel injection issues- the system is fuel rich (black smoke) and also fuel rich system can make the idle low. Many things can cause this but thses are just a few.

Hi, Anonymous it should be noted that the "AIR FUEL" mixture screw adjustment "ONLY" manages your idle and has no effect on any other circuit also any intake leaks must be repaired before the A/F adjustment procedure can be performed otherwise you will never obtain a proper idle and you will waste a lot of time chasing the impossible. The A/F mixture screw's purpose is to fine tune the fuel charge entering the combustion chamber. The following applies to both 2 and 4 stroke engines:
1. The mixture screw may be sealed at the factory with a Welch Plug please review the following video for removal.
https://www.youtube.com/watch?v=wAXcksgvDkM
2. The mixture screw manages a range of 3 complete 360-degree counterclockwise turns from the bottom/closed position.
3. The mixture screw should have a spring and o-ring for tension and sealing integrity.
4. Turn the mixture screw clockwise until it gently bottoms out, this makes the fuel charge very lean and the engine should not idle if it does then the pilot/idle jet is too big and needs to be replaced with the next size smaller.
5. Turn the mixture screw 1 and 1/2 turns counterclockwise to establish a baseline for starting the engine.
6. To fine-tune the idle circuit, adjust the mixture screw 1/4 turn in or out to achieve maximum idle RPM, wait 15 seconds between each adjustment for the idle to settle.
7. Never go past 3 full turns out this will make the fuel charge rich, foul plugs, and produce black smoke out of the exhaust, if the engine RPM keeps increasing past 3 turns the pilot/idle jet is too small and needs to be replaced with the next size larger.
8. After achieving maximum idle back out the mixture screw another 1/8 of a turn then adjust the throttle cable idle stop screw to 950-1050 RPM.
9. This procedure works great on 99% of all engines, for the 1% that demand a more robust throttle response on aftermarket monster fuel delivery systems additional tweaking outside the box may be necessary.

Running rich, poor idle, cuts out easily at low


It is not from water in the gas, something else is causing the problem, but I don't know what, yet. Does your bike have the new CAN wiring? Little thin wires running all over the place or the old style fat wires? If it is new style, you shouldn't have a problem with it getting wet, but the old style had 2 junction boxes up front behind the headlight, that doesn't like rain. It could have been enough to make it run lousy. Check it out and clean it if you have to. The next thing to check is the coils, the only other thing that can short out. Your bike is basically waterproof, so the washing might just be coincidence. check all the wires on the bike and under the seat, just to make sure nothing wiggled loose. Did any lights on the dash come on? Hope this helps. 2002 S4,,,99 750 monster
