I picked the bike up a couple weeks ago and its runs fine when i start it and its on high idle. After high idle shuts off.. the bike runs like ****. Its almost like its down a cylinder. Any ideas why that might be happening. It ran the other day for while with no problems. Then all of a sudden started having this problem. After high idle is off it sounds like and runs like a moped

 

I know i ask everyone when they have idle problems is the FI light blinking? It could be a number of things. Id look at the simple things first air filter, plugs etc...

 

Possibly a vaccuum problem... make sure all of your hoses are good. Best thing you can do is get a set of gauges and hook them up. Easiest way to eliminate problems on a street bike. Also, do you have an idle cable hooked up directly to your middle throttle body?

 

thats what im going to look into tonight. and i have a spare set of injectors to try tonight as well. one might be clogged or something and thats why its not running all all cylinders.. and no the FI light is not blinking.. thats what i thought of first as well.. thanks for the help man

 

i thought it may be a vacuum problem as well.. wasnt sure if it could be.. but im sure at this point anything is possible.. and no i dont have the idle adjustment hooked up yet.. im goin to put one on soon.. i only have the fuel mixture cable

 

Did you buy your bike this way and it's always been this way or did it just start donig this?

 

i bought the bike cheap knowing that it ran when he parked it but it had sat for a while.. got the the bike to start. and it ran like new. then we shut it off and went back later to start it and it ran like ****.. and hasnt changed since. that kinda makes me think that an injector may be clogged possibly.. once it was started we didnt change anything... i was thinking that maybe there was some **** in the tank that we didnt know about..and it got in and clogged something

 

That's a definite possibility if it sat for a while. How long did it sit before you started it?

 

i would say the guy had it sitting for a least a year and possibly up to two

 

Oh jesus... yea, drain the gas before you do something like that. The bottom layer of gas was probably in ok shape but once the rest of the sediment made it's way into the system that's when your bike became no bueno. Change your injectors, flush everything out, run the highest octane you can and see what happens.

 

i put brand new gas in but i think its very possible that something was in the pump ir the bottom of the tank and made its way to the injectors.. im gonna change them and see how that helps
