KEEP YOUR AIR FILTER FRESH
« on: November 05, 2009, 01:37:43 AM »
Some years ago I took my B12 with standard Ivan mods, out to New Mexico, from New York.

As I went through the center of the country and into Kansas, the bike started running a little notchy, sort of missing at low throttle opening. I checked the air filter... LOOKED clean enough.... then subsequently took the carbs off at a motel near Colorado... they looked pretty clean.

Took them off AGAIN into the mountains, this time to move the needles a notch.. maybe the thin air ??

Nope. Into Santa Fe in  the middle of a nightime, frightening thunder storm, and in the morning the bike would hardly start. Belched out some black smoke. I limped it over to the local Zook dealer, who had no idea and suggested I needed heavy motor work. I gritted my teeth and took the bike north.

Finally, around northern Colorado, I swapped the air filter for a new one, even though the old one just didn't appear DIRTY, just a little GRAY.

BAM! The bike suddenly ran like a raped-ape...... and the rest of the trrip was a smooth gas.

Change your air filter!!

Words to live by, China Greg !!! The stock bikes are set up to run sooooo leaned out that as soon as there is a small restriction caused by a dirty filter....all kinds of nastiness starts to happen, as you so clearly posted......and air filters are NOT that expensive....even the factory ones. Do your Bandit a favour....change the filter NOW......
(or next spring, if you live in the snow belt).
