Today, after got really frustrated can't spend my day doing some quiet studying for impending CA exam, because I have to look after my daughter (The Baby sitter who supposed to look after her, is MIA, so no one to after her !!!). Instead, in the late after, I decided to work on my B250.
I Just want to change the oil and clean out the air filter (I end up washing the air filter because the near by suzuki dealer somehow don't have B250's air filters... so have to find some time to look for one in the part of the Melbournian city). OIl is absolutely dirty, so I am glad i changed the oil. Took off the air filter and it is full of black muck. Decide to wash it in warm water and let it dry in the sun.
Now tried assemble the other things back first, because I can't occupy my in-law garage too long, so I decided to assemble everything back, minus the air filter (Still in the drying process).
Now I am trying to start it, it is fine, I let it run a little while, just to ensure the engine oil settles in.... but then, the bike starts to cough and choke, sounds like running out of juice...... and it finally died....... Tried to start it again, nothing. The engine seems to be turning, but no ignition.... Keep on trying to start it until the battery is out of juice...... Try bump start, still don't work...... What is going on !!! Help ??

Your bike was tuned with the air filter in, not out. Once the filter was out of the box, it went full lean causing the symptoms you see now.
Replace the filter and charge your battery, you should be fine.

Check to make sure your vacuum line is on your petcock. Also check to make sure your petcock is in the on position. You could've been running off fuel in the float bowls.

:clap:

The vacuum line is definely in and I checked the line three time as well, as there are fuel in the vacuum line. When I start it, the tacho barely move at all, there are sound of engine turning, but no ignition.
I will try put the air filter back in again like TomacGTi, maybe that will help abit..... BUt then, I got a Bucks nite today, starting 11am, so the rest of teh day will be wasted (As in drinking !)
Will report back to you guys to see how it goes.......
-
fuel in the vacum line???? :yikes: change the plugs or atleast pull one out and see if you have spark
-
As Jay noted, you should NOT have fuel in the vacuum line? Maybe you meant the fuel supply line?
Anyway, you can also pull out one the carb drain screws to see if you have fuel in the float bowls.
From you description, it certainly sounds like no fuel to the carbs...
-
Fuel in vacuum hose: hole in diaphram meaning your petcock is pretty much toast.
Set the thing to prime in order to run it and cap off the vacuum spigots in both the petcock and #1 carb. If your petcock is the same as a B4 then if you remove the screw towards the top of the petcock and rotate the knob past, fuel will flow.
Good luck!

This would be OK if your carbs are up to spec oring wise and float needle wise...If not then you will flood the cylinders or always run rich on some cylinders or maybe get fuel in your oil...we all have done it but the proper way to fix it is to get a Pingle fuel valve or get a rebuild kit for it...which again is probably a common part used on a bunch of fuel valves...that Suzuki uses. :motorsmile:

Some updates .....
Sorry, not the vacuum line that has fuel, but the fuel line has fuel. I tried draining the carb, and there are definitely fuel in carb (Except 2nd carb from left, since the screw is frozen tight).
I will need the weekend to take off the tank again and check for sparks...... and wetness on spark to be sure the fuel did get to the engine.
Damn it !!! its Summer here, and I can't ride to work !! damn damn damn !!!
PS - anyone know how to loose a frozen screw, where the socket is also ruine by previous owner?
-
Vice grips and PB blaster. Always loosens the hardest stuck bolts. You'll probably need a new screw though.

Thanks Delimus.... I think the problem going to be reach to that bolt. Hope this PB Blaster will work the same to penetrate through the carb drain bolt at 2nd carb chamber...... Since its raining today, looks like no fixing bike tonite for me....

I use a automatic :stickpoke: center punch :trustme::yikes: just on the very end of stuck screws :banghead: couple easy pushes and the screw comes out :motorsmile: also works great on hem pesky brake cylinder cap screws :bigok:

With all the time dinking around trying to get to that screw out,you'd be ahead of the game just pulling the carb bank,pulling the bowls off and cleaning them out correctly........... :thumb:

I want to !!! Two problem....
1. Not living at own place atm, at in-law's... and the Father in-law is a prick of a person, so can't really use his garage.....
2. :yikes: Too scare to pull it out, as never done them before........ and will need to wait till I move to my new place THEN I can take the bike off for a few weeks to do work on it.... meanwhile, I still need to get the bike up and running to ride to new place (without get a trailer to toll it there)
Anyway, status update......
- Spark plug is dirty, cleaned it out and definitely spark coming otu (accidentally zapped myself).
- The spark is wet, so presume there is fuel in teh engine.......
- Notice the 1st plug connects to the spark is abit loose.... I needed to use screw driver to push it down to hear the double "Click" sound when connecting the plug socket to teh plug...... possible cause of no start......
Anyway, Batteries are fully charged now.. will try install back to teh bike and try start again.....
-
I would suggest new plugs :thumb:, and your loose plug cap to spark plugs is surely not the cause of your no start :trustme: if you have spark and fuel :motorsmile: you either need new plugs :thumb:, your wires are crossed to which plug they go to :yikes:or your getting to much fuel :annoy:...
-
if you have spark and fuel, you either need new plugs,your wires are crossed to which plug they go to or your getting too much fuel.
If the wires are crossed,this might help......

New Update of the Dilema........
New Spark plugs been added and tried starting again...
Result: Full of cranking sound, and no tacho movement, and a few backfire ..... Sounds like too much fuel now after so much cranking .... How do we fix the problem with too much fuel ? I checked the wiring, it is definitely like 97af's picture, so it is not the wiring......
This coming weekend, I'm moving to the newly "Rented from the bank" house of mine, so if I don't fix this, I have to load the bike onto the truck, so I can continue troubleshoot it....

Do you have spark on all plugs...pull them all out put plugs in caps ground on motor crank look for spark... no tac maybe check the power wires that plug into the coils maybe one is loose it is common

Some good info here:

Why not just pee on a electric fence :stickpoke:
Jay,one of the best tech tips yet but............. :rofl:
I don't pee on other people's properties :stickpoke:
The most helpful tip of the thread. :thanks:

lol :motorsmile:

The leads from the coils to the caps look right.... mixing them up WILL result in some pretty spectacular backfires, though...

When I replace all of the spark plug, I have plug the new spark in the cap and test spark against the side of the engine, and there are definitely have sparks coming out.....
After I changed the spark inti the engine, there are two cap is abit hard to click in, so I did ensure they are plugged in (Unless they still not plugged in properly........)
My father in law has checked it as well, and he couldn't work out why either.....
I have to check the coil side of it though, maybe that is the cause, as the cable is abit tight around there. If this still doesn't work, I would have to wait for sometime next week, as I have to move house on this coming saturday (Finally have my own workspaces !). I rented a 4 ton truck, so I can get all my furniture in, as well as my bike onto it to be shipped down (The misses is wondering why do I need a 4 ton truck when we don't really have that much furniture):P haahaaa ...... :trustme:
Further work
