Bike boggs out at idle but revs good

Hey people, it's a 81 maxim 650, it's been sitting for a while so I cleaned the carbs and set the floats, every once and a while when I start it I get it above idle it revs good and then when it goes to idle when I hit the throttle it boggs out and will not run again till I hit it with starting fluid but I got to keep it above idle or else it will stall, it sounds good while trying but no idle, do I have to change the idle jet or is that something I can tune out of it? I'm Wondering if someone else has run into this problem before, looking for some help , thanks

 

what idle speed are you setting it for ?
Idle has to be set when motor is all warmed up.
could be your pilot jets are still dirty the pilots control idle as well as the mixture screws did you remove them and replace the little orings?
Inside your Carbs
are you using the enrichment ( Choke) circuit to start bike? pick up tubes in bowl could be clogged.
did you wet set the floats for the fuel level?

Setting the fuel levels

are all your header pipes getting hot?

 

Agree with XJ550H ...your carbs are not fully cleaned, suspect your fuel enrichment circuit is plugged (choke) you will need to pull carbs and bowls small jut in bowl is most likely plugged up on one or more of the carbs . Are you running stock airbox or Pods mad ? if you have pods there is a possible problem with jetting . Another item is carb synch is off.

 

Are you using the erichment lever when starting, and letting the engine warm up before using the throttle?

 

For the life of me I can not get those two passages clear on the carb bowls, the ones that have that brass tube come into it from the carb itself and sits at the bottom of the bowl, fuel is supposed to flow through their right? I blew air threw there but I'm getting nothing, these carbs were really gummed up

 

Is got stock air box but not hooked up yet, there not the easiest to put on

 

If you have the enricher plungers open, the air will go through if the passages are clear. If the plunger is closed, no air can get through even if the passages are clear.......

 

The brass piece is clean, I'm asking if the two passage ways one the carb bowl are supposed to flow into each other? I can not get air or liquid to flow to either other side of the passage on the carb bowls

 

Mis-understood the question---my bad.

If you can not get anything to flow from the bowl into the well, then the jet at the bottom of the well is clogged/plugged. It MUST be cleared. It is pressed in, so you cannot pull the jet out-- you have to work it with piano wire, fluids, etc....... But you HAVE to clear it

 

If that's the case then all four of mine are clogged, I uploaded pics because pictures say thousand words, in the two pics, they should flow into each other right?

 

Eewwww....definitely clogged. You got your work cut out for you. Fwiw, I have only ever had ONE jet that I couldn't clean out. You'll be able to get it.......

 

OK I got work to do then, hopefully I get them clean, I will let u know, thanks for the info

 

Soak the bowls in Berryman's for about an hour. Follow up with piano wire or guitar string if needed.

 

Or longer...... I've had some that had to stay in a dip for several days before it would finally soften enough to blow out. The biggest challenge is training yourself to NOT rush. Learn that it takes as long as it takes. Do it RIGHT, not necessarily QUICK.

I wouldn't leave float bowls in Berryman's more than a few hours at a time. It will etch and possibly discolor the aluminum. Other carb dips are fine for longer periods of time though.

 

I use the Napa gallon can, not Berryman. The only thing that discolors, so far, has been brass... It gets a red color, then eventually black if left in too long, then Waaay too long. But, it wipes off and the metal can be buffed a bit to bring back most of the brass color.

 

Update, I have two cleaned out, I let them sit over night with carb cleaner down the holes and then blew them out with air in the morning, I have the other two sitting with the carb cleaner now and will try to blow them out tonight, I will keep trying till I get them, might try the Berryman stuff, I'm going to give this one more try, thanks for all the info, appreciated

 

Awesome I got the other two clean, I have soaked them twice today for five hrs at a time today with carb cleaner with no success, then I thought why not boil them, 10 15 min on the stove then while still hot I blew it out, like it never was clogged I should have did that first

 

Have you guys tried an ultrasonic cleaner? I use one on small engine carbs and am always amazed at how much debris comes out of carbs previously "cleaned" with carb cleaner and air.

 

I am making one right now, I'm using a palm sander and a container

 

Waves do not travel around corners. The internal fuel passages have several sharp corners. You will still need to blow throught the passages after a long soak.

 

I have been using the Harbor Freight unit for almost 4 years and it works great. Really cheap with the coupon!
