CBR wont start!

[Str8 Jacket]

Yeah I need it i think, new bike is going to be black, with a bigger engine than my mini and very loud.......no more clues, hopefully see yah tomorrow night though if its going!

owwww be like that then!

Rides seem to still be going but my headlights suck more than a mosquito and I cant even see 2 metres up the road so sadly I wont be there.

Haha, fair enough, Im meant to go and get a new front tyre and brake pads for it tomorrow, but dependant on if i can get it going.

Check your leads anyway cause they may have been knocked. You holding your tongue the right way?

Have you got your air feed from the tank in?

There appears not to be an air feed from the tank, there is only the tap, and the pipe exiting the bottom into the drain hose.

Have you checked your tyre pressure?

have you tried reseting your router?

booyah!!!!! :

[skelstar]

Do you think your new bike will have the petrol stored in a tank?

Advice: dont buy the new bike until you sell your old one. You loose all motivation to sell the old one. I should know .

[COP_B8]

Yes it will be in the tank, its a jappa.

Is it getting the gas to all 4 cylinders? You haven't accidentally knocked something out of place with all that vigorous polishing or when putting the tank back on? Spark?

[Macktheknife]

Start simple, check fuel to all cylinders and then spark to all. this will often sort it out or lead you to the problem. After that check timing and lead conections. Let me know if you still dont get a winner.

[COP_B8]

How would I check fuel to every cylinder, spark is a bit more trickier, the leads are located out of reach, i have jiggled them to make sure they are on, spent the afternoon CRC'ing and cleaning everything and making sure that all electrical connections were on, still not going though.

One thought was the fuel pump but there is plenty of fuel in the line after it so it must be doing its thing.

My guess is that by this stage your problem will be a flat battery. The batteries on those 400's never had much grunt. I found with my NC 23, if it didn't start in the first couple of seconds on the starter, it wouldn't start at all (i.e. using the starter for 10 seconds at a time would only drain the battery super fast). Also found that depending on the age of the battery, the battery didn't have enough power to spin the engine up and provide sparks at the same time. The engine would catch just after releasing the starter switch.

It also sounds like you've well and truely flooded the engine. My suggestion would be to try bump starting it with all the lights etc. turned off. (And charge up the battery if you can)

Note: Checking for fuel - look at the bottom of each carb & you'll see a nipple with a bleed screw. Stick a bit of hosing over the nipple (to stop petrol pissing everywhere) & open bleed screw. If petrol comes out, you're probably getting fuel to that cylinder. Repeat for each carb. With the bleed screw still open on one of the carbs, make sure the fuel pump is still working & fuel is getting delivered to the carbs, by turning on the ignition. Should hear the fuel pump clicking away & more fuel shoukd get pumped out.

My 2c.

Yes there is fuel in every cylinder and spark in all of them.

Coil, leads and check the CDI

Have you tried cursing loudly? Threatened it? Kicked the tyres? Have you considered torturing it until it gives iin?
If all else fails, try making an offering to the Gods of motorcycling...

Sorry, no idea mate...
