Maxim X needs a new home

I am so tired of working on this bike. I have rebuilt the carbs following the directions in the church of clean. Bike starts right up, idles great after the carb adjustment and sync. Accelerates great.....but at 55-60 cruising speed, I get missing type action, like it's running out of fuel. Twist the throttle and it catches up and accelerates fine again. Anybody got any ideas...other than I obviously don't know what I'm doing.

Jamey, I had what sounds like a similar issue and it turned out to be a clogged gas cap vent; it's worth checking. The cap may be clean on the outside but very dirty on the inside...

To diagnose this Jamey do a plug chop right when it's acting up. Ride it for several seconds while it's missing and then hit the kill switch and look at your plugs. Dry and/or white and it's lack of fuel, normal and you have ignition issues (TCI).

Don't give up yet, you haven't brought the full attention of the forum to bear on it yet.

Also when my 550 was running lean it was doing this around 45-55mph, I had low fuel levels and two clogged pilot circuits.

 

I don't think ignition is the culprit here. Bike was running fine until it sat for a while. I went to start it one day and gas is pouring out the overflows. pulled carbs and cleaned, put back & it ran great. This happened several times over this past year so I bought the rebuild kits and installed. My guess is I don't have the floats set correctly so the carbs need to get pulled again, what a pain! This bike is on it's way out of my fleet, whole or in pieces. I just don't have the time or interest to keep working on this.

 

Your guess sounds correct, it sounds like a float level issue.

 

I recently had a similar problem. If setting the floats works, great if not and gas still flows out, you carb floats maybe saturated.

 

So Jamey, any updates?
