today i went riding and bike was running great

i went to install a k-n-n filter and now the bike wont start up

it will idle then die

even when i put the oem filter back in it wont start

i have it on choke all the and its like starving for fuel then dies.

any ides im sure carb clean will be needed thats my guess.

 

I assume that after resinstalling the OEM filter, that you re-closed and sealed up the airbox?
At any rate, if you personally don't know for sure that the carbs are squeaky clean, that is definitely the first place to start with fueling issues, especially if the bike ever spent a good deal of time sitting, and not running.

 

Check your fuel lines for a pinch. Vacuum line to the head cylinder, skinny line that dangles from you tank is also a vacuum breather hose and of course your fuel line from the petcock to the carbs. I recommend breaking out a flashlight and following every millimeter. I can alomst bet it is a pinch in the lines, at least that is what it sounds lines. Runs for a few seconds and dies.

 

hey thanks for all the info to everyone, i found out that i didnt hook upone of the hoses to petcock,the main fuel line was hooked up but not the other skinny hose, also it would help if i turned on the fuel, dohhh. lol

 

It's true, that is a "dohhh" moment , but at least now it's !!

 

Is it necessary for the vacuum lines to be plugged in and the airbox closed up for the bike to run? I'm trying to bring a racer back from the dead; I have a remote gas tank hooked up but no vacuum lines connected and no air box mounted. It kind of runs if I spray starter fluid, but that's it. Is this a similar problem?

 

when i first brought my bike home i had to use ether to get it running cuz it sat for 2 years. after it ran on the ether i just set the gas tank on and hooked up the fuel lines and it fired right up. idled higher than usuall obviously but it does run without the airbox
