This 1994 M900 Monster is shown with Corbin seat, stock mufflers, K&N Stage II carb kit, K&N open airbox and filter, Bitubo steering damper, ClearView windshield, misc. carbon fibre bits, RKA tank/saddle bags, and Traveler's Club duffel bag. I rode and tent camped all over East Tennessee, western North Carolina, southeastern Kentucky, and north Georgia. Around 2006 I sold this bike to a fellow in South Carolina. I hope he has a much fun with it as I did.
Which plugs do you use in your carburetted M900? I'm used NGK DPR7EA-9 with a 0.7 mm gap and 89 octane fuel. The plugs occasionally foul in stop-and-go traffic, so I carry a brass brush to clean off the carbon. After one or two cleanings, I replace the plugs with new. I believe this fouling is due to an over-rich mixture at low RPM and/or low voltage to the coils at low RPMs.

I tried the NGK DCPR8EIX Iridium plugs. They worked OK for about the first 100 miles, but then the rear plug sooted up and started misfiring. I got the same results with a wider than normal gap and with a spec gap.
TiresI used to run Dunlop 205s but now I'm trying Michelin Pilots to see if I get longer wear.
Dave Mordecai recommended this modification to me, and it works well on my 1994 M900 with 38mm Mikuni BDST carbs. To eliminate the abrupt throttle cut-off when decelerating and to make the throttle modulate better off idle, disable Mikuni's Coasting Enrichener Circuit in the carb. (Note: read the entire carb section of the M900 shop manual -- these carbs are complex.)
The stock bars cocked my wrists at a bad angle and were uncomfortable on longer rides. I installed Flanders Harley XR750 style bars. Flanders also supplied me with longer steel braided brake and clutch lines and a longer throttle cable. Juan and the folks at Flanders were very helpful. These bars are much more comfortable. One problem I have discovered is that it was necessary to file down the small dimple on the light switch and starter switch that fits into the small locating holes drilled into the stock bars. Don't overtighten the starter switch or it will stay "ON."
To reduce vibration, I inserted a bicycle innertube through the handlebars, then filled it with sand in the middle section and lead shot on the outer sections. Tie off the ends of the innertube and tuck them back in the bars. This lowers the natural frequency of the bars.

Cold Weather Riding Tips
Oil Cooler Shield -- So your engine oil will get up to temperature, cover your oil cooler when it is below 60° F. I cut a cover out of a Guinness Stout can using a pair of scissors.
Full Fuel Tank -- To keep condensation out of your fuel, top off your tank at the end of every ride. Close the petcock as you near home to empty the float bowls.
Fully Charged Battery -- Protect your battery by keeping it fully charged with a battery tender. I use Superior Electronics Accu-Charger. This seems obvious, but repeated starting in cold weather can run your battery down. Also my M900 alternator has trouble keeping the battery up when idling or at low speed.
Long Underwear -- Wear polyester or other synthetic long underwear that doesn't absorb water. This should fit close to the skin, so avoid a tee shirt.
NASA Space Socks -- These socks are woven with aluminum thread to reflect heat back to your feet. They are available for cheap from various outfits such as Sportsman's Guide. Wear heavy socks on top of the Space Socks.
Waterproof Insulated Gloves -- I found a pair at Wal-mart for about $7 that work great. The waterproof shell keeps the wind from penetrating. If necessary, get some NASA Space Glove Liners (see Space Socks above).
Scarf -- Wear a fleece scarf to seal out the wind around your neck. This has a huge effect on keeping you warm.
Jogging Pants -- To protect your legs from wind and rain, get some cheap jogging pants with a Nylon or other synthetic water proof/resistant shell to wear over your jeans or leathers. Mine are Reeboks for about $8 at a discount store. I've also seen them at Wal-Mart.
