taking apart and cleaning carbs

I am having some issues issues with my carbs that is making my bike unrideable. The bike was working fine until a yesterday, when the engine could not stay on without any throttle. The bike would even stall if I attempted to use some/all choke. Of course, I played around with the idle screw to make up for this but now the engine seems to stick at high RPM if I give it any throttle (vacuum leak?).

I would like to take out the carbs and take it apart. My goal is to clean up any problems remove any gunk on the jets. If I do decide to go this route, is there any way that I can take apart the carbs and put it back together without replacing anything such as gaskets?

yes you can  :cheers:

ust be VERY careful 1. not to loose the tiny o-ring in the cap 2. Not to tear the bowl gaskets 3. dont get carb cleaner on the gaskets... Clean em well and re-assemble  :thumb:

What year is the bike ... and when you say it wont stay running ... what exactly is it doing/sounding like.

Your problem probably is in the intake manifold, not the carbs.

Cool.

Tne bike is a 97.

Funny you say that because I just replaced the gaskets on the manifold! this afternoon I wonder if old, died up gaskets would cause me any problems. I should have checked for a vacuum leak but I cannot get this bike started today!

The bike was running fine until Friday afternoon when it just would not want to stay on while idling. I noticed this when approaching an intersection and the bike stalled and I had trouble starting it...I had to give it a ton of throttle while spinning the starter motor to get it going. Even then, I had to give it some throttle to keep it from stalling again which was challenging to me during the rushhour traffic on Friday.

I tried driving the bike a bit yesterday and it sounded horrible....like it was running on one cylinder. I pulled the plugs yesterday and the left one was black and wet while the right side was dry and running a little lean (whitish/brown).  It did eventually run on 2 cylinders but it was sluggish and I couldn't maintain anything over 3-4k RPM.

I have the carbs off now and I am taking them apart. I have no idea the size of my jets and I was wondering if there is any way to identify the size of them by any markers on it. I have doubts the previous owner(s) keep it stock...

Dr.Sparkie

could be a stuck float valve causing the one carb to drown in gas.

anyways, when taking apart your carbs, use a tray or pan, and two bowls. put all the parts from one carb in one bowl, the other and the other, and never remove the carbs from the tray.

Put some pics up and I'll tell you what they are, and see if you can read numbers off them ...
stock on a 97 is 122.5 mains, 37.5 pilots 5DH bla bla needles ... no multi groove needles.
Put up pics as to what come out. I'll identify it in a sec.
Cool.
