So my b12 just decided it wants to get 25 miles less to a tank and I'm not sure why now I know its running rich and I'm thinking I fouled the plugs but I don't think it would just happen that fast so does anybody else have any clues before I dive in cuz it is my only mode of transport at the moment

anybody? i know there are a ton of b12s and b12 lovers here somebody help me out lol

I would give it sync and replace the plugs

That's the plan but I'm just confused with it happening in one tank I've never seen that happen it's always been gradual and it seems like it's still running top notch just rich and maybe takes a little longer to warm up

I don't know about bandit carbs but that's weird happening in 1 tank and running rich. Might want to open them up check the emulsion tubes jets and float height.

Did you fill it with 89 by accident and not 93? I could see that killing the gas Mileage possibly. The sudden running rich is weird.

I never run 93 lol though it does do a little better on mileage power is about the same and it doesn't knock plus it's only 9.5/1 and only ever sees 10000 rpm at most but usually is very low so I wouldn't think it would make a big difference

id try the plugs. air filter and carb synch. also change of season can change runabilty

 

[81cm400c]

Looks like that's what I'm doing hopefully it fixes it pulling those carbs out I'd a pain lol

Not sure about yours, but my B12 had pod filters and it absolutely loved cooler weather. It definitely had more seat of the pants power when the temperatures dropped. That, combined with my penchant for wheelies usually netted me worse mileage in the fall than in the summer.

 

[81cm400c]

I gotta say it does feel a bit stronger up top since the weather cooled off and I've been trying to get better at wheelies do it's in the air any chance I get lol but I stopped and toffee like a sensible human being for a whole tank but same result

i love winter with my tuning setup and pods, except when i lose traction even in triple digits under wot with warm tires. i wish i had a bandit that extra pork keeps the bike stable!

a boilers peak is the colder weather.
