I haven't tried anything but the Autolite 4162's. They replaced the original NGK's at my first plug change. They're Dale Walker's favorite plug for the B12, so that's good enough for me. They're about as cheap as the Champions and a couple of us local Banditos have convinced our local NAPA to stock them. (Other area auto parts stores can have them in a day, too.)

Yep I've heard they are the ticket for the B12's with the airbox/carb mods... What is your take on big bo's problem? Kinda hard to help a bandit brother if they aren't doing their own work! It just makes a good mechanics job harder who ever that maybe! I have been in that situation..

Well, it's kind of puzzling how he was getting better than normal mpg then all of the sudden things went into the tiolet - big time! Something had to have changed to make it do that. Timing is fixed, so I doubt that's it. It sounds like the carbs have been checked and everything's copecetic there. He's not complaining about any power loss, so that seems to eliminate mechanical troubles like a cam chain that's jumped a tooth, poor compression, etc. It's a real head scratcher from here, which is why I hadn't posted any troubleshooting tips - I just don't have anything to add.

I guess if it were my bike, I'd start with the basics and start checking everything. Make sure the cams are timed right, valves adjusted right, the timing components are all where they should be, the plugs looks good, compression is up to spec, air filter(s) clean, and so on...

When the milage went to crap I replaced the aircleaner. It had a small amount of oil on it. Sence then I have just dealt with the problem.

I ordered plugs today. Will be in Wed. I run Molbil 1, Ivans jet kit and Scorpion pipe. I installed a Busa shock also.Some of the pair system is disconnected. Caps on the carbs. The whole system has not been disconnected.

Tomorrow I will install the new Autolite 4162 plugs.

Well I put the Autolite 4162 plugs in the Bandit today. It sure starts faster.
Seems to pull harder also. I only got to put 4 miles on her today. I will try and put 50 or more miles on her tomorrow.

The factory NGK`s did not look bad.

Put 16 miles on the Bandit today. No long miles because of WW&F, work, weather and family. The milage seems to be the same. At 10-12 miles I loose one bar on the fuel gauge. Lowered the rpm to 1200. Throttle seems crisper.

This winter 05 / 06 I didn't ride the bandit much at all. When I filled it up with gas I was getting 38mpg, normally it should be 42 / 43mpg. Well, I ran a tank out in one sitting and it was back to 43mpg. I'm wondering if gas evaporates from the bandit while it sits? Or maybe it was just that I rode it running short errands and had a lot of "choke" time in start ups?

My mileage has never been anything to brag about. I still have my track gearing on now.(15/51) Havn't been able to get it out much anyhow this time of yr. But I'll be changing my tires and gearing back to my48rear for normal driving. And I just oredered a 16 tooth counter to run w/ my 48 wich should bring me close to stock gearing. I'm hoping this helps my mileage.
As far as the plugs, I've noticed the cross reference charts are not right on the $. I've run the Autolites and NGKs. If I go by the chart my NGKs read hotter. Where as the A.L.s ran rich.
100 miles and I need gas!Hoping with the taller gearing(and maybe a little wrist cotrol) I can get 130 mile out of a tank.

Since the tank is vented, it certainly can evaporate! Also, consider that as gas sits it starts losing octane. If it's less than a month, it won't drop enough to be noticeable, but after that, it starts dropping. So, if you're out running around on old gas, your mpg drop could be effected by that as well as evaporation.

My 30k miles 1999 1200s with a high level race can, big hole in air box , K&N + dynajetted carbs and rolling road tune did 54mpg (UK gallons) from W,Yorks round the Lakes and back 90% A roads.
And about 39mpg to work and back 20mile round trip.

I determined at the end of last season, that my rig got 19 mpg city/21 mpg highway.. just slightly better than my GMC Safari.. I need a scooter to save on gas costs ...

54,000 km, 950 lb rig, 44/15 gearing, Stage 3 HS carburetion, '90 GSXR intake cam, timing advancer, and absolutely no common sense at the right wrist.
