Bike cuts out under load?

Turn the switch on to PRI and leave it for 5 min, see if the level stays at the same height. Is the height the same as the top of the float bowl.

The fuel line will go to the carb/s, vac line will go to the intake betweent he carb and cylinder head, probably on the front cylinder.

How high was it in relation to the carb? I would say it should be around 11-13mm below the top of the float bowl, if the level keeps getting higher, then you have a leaking needle/seat in the carb, if the level is too low, your floats are set wrong.

It's a bit hard to see over teh interwebs

Lol so where is the float bowl? I'm not sure how high it needs to be

iraq.. think its code name for a WMD

2 joints should get it high enough..

Did it change when you turned it to PRI?

Did it change when you turned it to PRI?

Closed it off and took the hose off, it's been sitting for about 3 min and the level hasn't changed

I tightened the bolt back up and tried to start it, it wouldn't start

hasn't moved in pri, it's been 7 min

should my bike be on when i test out the float level?

The level wont change if youve turned the drain off.

Sounds flooded now. Open the throttle wide open and dont use the choke. Be ready to close the throttle as it will rev hard.

Then try what I said again. Leave the drain open and turn on to PRI. Leave it and see if it rises.

Cool, got my bike outside, got it running, turned it off, got it inside, put the hose on the carb, drained it, sucked on the hose to get it going, let it sit for 2 min, then switched it to pri and let it sit for about 5 min and it hasn't moved

float bowl issues would be seen when starting the bike and while its running. the float bowl would flood over night and cause issues for early morning starts, i would have thought. a flooded floatbowl while running would cause issues while hes riding anytime, not just under load. a flooded bowl should still start with the throttle fully open, unless its just dumping fuel in the intake.

it's low on power, black plugs, guzzling more gas than usual and cuts out after loading the engine with an uphill run where a 20min wait will allow it to restart. replacing the plugs helped and choke doesnt work. dont worry about the choke, different engines need different amount of choke, maybe yours only needs it when FROZEN.

i only know of one thing that would cause all these issues, spark issues.
i'd be pointing towards the coils, bad leads, magneto (or pick up sensor) or control box.
coil, pick up or control box could be over heating due to the highier rpm your doing while going up a hill.
might have a lose wire or connection
since its not starting all all for 20min, i'd forget about the coil or leads having issues, for now. it should pretend to start on 1 cylinder.
id test for spark the next time it dies. take a old plug with you. as soon as it dies, unplug a lead, plug in the old spark plug, hold it agianst some bare metal (like the engine) with some pliers (so you dont get shocked) and check to see if there is spark. do the same for the other cylinder.

That's a fair point, but why is the plug temp still in range if it's weak spark?
The chokes could be stuck or leaking anyway, I've had split rubbers in my chokes, fuckin' annoying

20min wait will allow it to restart

sort of, letting it sit allows me to ride again but only for a brief period of time.
Like this morning on the highway, I had just gotten to the top of a hill at 100 when it cut out. I sat there for 20min, started it and rode down the hill. at the bottom it died. let it sit and repeated the process till i got home. - but it tends to die on hills mostly.

My bike has no temp gauges so i don't really know what's up.
The control box is under the seat, i'll give it a check for loose cables tomorrow.

i'll take it for a ride tomorrow and test the sparks out
