The only problem with some of the advice here, is that it's a 2002 Blackbird, so it will be fuel injected.

    Check the oil. If there is fuel in the oil, then an injector/s could be stuck open and fuel is flowing into the cylinder by flowing past the rings. Fuel in the oil could also be a ruptured diaphragm in the fuel pressure regulator letting fuel in the vacuum circuit letting it into the manifold. Either problem is not such a big deal. Go onto Youtube and see haw to clean injectors whilst off the vehicle. For the fuel regulator, pull the vacuum line off the side and test for fuel.It will most likely smell gassy, but not always.

Had the same problem with mine, been stood for 1 year. Put a new battery on it everything was fine passed the M.O.T. Waited until the end of the month to tax and it wouldn't start. Plenty of petrol in the tank, wouldn't crank over on the starter, but could hear the fuel pump kicking in. Looking for a fault and kept trying it, checked for loose wires and blown fuses to no avail. Then i noticed fuel light came on checking tank was empty. Wondering where the fuel had gone I found the engine had flooded into the crank. Stripped everything down found the problem was neutral switch was broke. Check this hope it helps you, mine in the 1999 fuel injected model. Cheers Kev :o)

SOURCE: I have a 93 cbr 900 that will turn over but not fire up.

Carberator are gummed up because of improper storage. They will have to be dissassembled to solve this issue... You can test by giving it a wiff of starting fluid, when it fires and shuts down you will know it's because of lack of fuel.

I can't solve this(there are litaraly hundreds of things it could be) BUT I can give you a way to narrow it down a bit.
I'm thinking it may not be running on all cylinders and an easy way to check is to start the bike from cold(do this test in the first few seconds after starting from cold DONT BURN YOURELF),put a bit of spit on your fingers and quickly touch each exhaust header in turn, to see that they are all warming up equally together.This will narrow down if your problem is related to one or more cylinders.
If one or more of the pipes is cold/er than the others then you know which cylinders are causing the problem.
If you find that this is the case- one or more of the headers are cold then.
Remove the spark plugs-Keep in order.Examine the plugs-used plugs tell a story.How do they look?clean?black & sooty?Are they all the same colour?
Re-fit plugs to caps,sit plugs on metal of rocker cover,press starter - cheack for spark on all plugs.DO NOT HOLD OR TOUCH PLUG/CAPS WHILST CRANKING-WARNING - HIGH VOLTAGE- CAN KILL.

I can also suggest a few common problems that bothered the v-stars/viragos.
They were notorious for open circuiting their spark plug caps on either cylinder.Having the coils tested will confirm this. If you have a multi meter let me know & i'll guide you through testing them.

Air leaking at the inlet manifolds-where they bolt to the cylinder-test this by spraying with wd type spray with engine running-if engine revs change-has air leaks(sucking in wd & affecting mixture.)
They even pop the carbies out at the front some times & **** air there.
The inlet manifolds also have hoses & plugs on them(for checking the carbie balance/vacume fuel tap)Check all these for splits & tears-common depending on the condition of the bike/milage/fuel used.
This will not solve your problem but may help you to isolate where your issue lies.

I hope this is somewhat helpful & I'm happy to help if you need after following these suggestions
Kind regards Andrew Porrelli

I hope that this is in some way helpfull.

If it's coming from the overflow, try a new radiator cap first. They do get weak and won't hold the proper pressure. Be sure to check the pressure rating labled on the cap and replace it with one of equal rating. Good luck!

My CBR 1100 XX is not idling but gives instant reaction on throttle with an initial spluttering and it revs very strong but it's not holding idle and the choke makes no difference and the manual idle

Hi, Anonymous and the usual suspects are:
1. Idle speed improperly adjusted.
2. Air fuel mixture screws not properly adjusted.
3. Inlet system air leak.
4. Leaking accelerator pump.
5. Loose low-speed jet.
6. Plugged low-speed jet.
7. Contaminated or plugged low-speed circuit.
8. Enrichner valve/choke not seated or leaking.
9. Multi carburetors out of sync and need to be balanced.

I have a 97 Honda CBR 1100 xx Super Blackbird. What fuel should she be running - leaded or unleaded?

Leaded fuel is not sold anymore. Unleaded is the only choice you have. On a sport bike I might run the higher octane fuel for a little better performance.

1997 Honda CBR 1100 XX. Bike builds idle slowly when cold . right side exhaust is forceful and hot while left side exhaust in minimal and warm only. Changed plugs and made no difference. Seems to idle...

Clay, you have a tiger by the tail. There are a lot of little parts to the carb system. I will try to assist you in the basics without carb removal. This may require a few replies back and forth. Start by turning off the gas then drain the carbs. Now turn on the gas and check to see that fuel flows into each carb. If gas starts flowing out of all the float bowls, now that the gas is back on, then all carbs are getting gas. To drain the carbs just remove the drain screw on the bottom of each carb float bowl. Two carbs have the drain screw on the left, two have it on the right side. Reply with what you find. tombones49_51.gif

bad gas maybe ...try fresh gas then some Seafoam fuel system cleaner... if you can get it running. also it might have a weak battery...trickle charge it four five hours then try again......battery votage after trickle charge should be minimun 13v.

My 81 Honda gl 1100 was not winterized. Installed new battery. Cranking fine. Wants to start. Smell gas, probably flooded.

You should drain your gas, gas line, and carbs.
Try putting in some fresh gas and see if it wil fire up.
If not a carb rebuild is more than likely going to be needed.
