Help with 2000 Monster 750

[The Stig]

Are there any Monster experts in Southern Maryland (St Mary's county)?

My 2000 Monster 750 is running rough at low rpm. It is running rich(black smoke/flame), 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.
