Wont start The bike is turning over it just doesnt start...Problem started happening last week. After messing with the reserve tank (flicked it on the off) the bike started and I was able to make it home. Today it is doing the same thing just wont spark...any ideas or commonalities with these bikes?

i could not find a schematic of a 96 cbr400rr, so guessing this bike is not from the USA. however, there should be a master fuse near the battery on the positive side mounted to the battery box somewhere. i would check this fuse first to see if its burned out.

also, is battery fully charged? might have to top charge the battery to get good juice if its old (>3 years) and been sitting for a bit.

good luck.

If you tried to start the engine for any length of time, the plug would be damp and smell of petrol because fuel was being drawn into the combustion chamber. Without spark to ingnite the mixture, it would cause the plug to become damp. I am assuming you fitted the correct spark plug and that it is gapped correctly.

I don't mean this to sound foolish, but I would suggest you make certain the emergency kill switch has not been accidentally switched off. Also, if you have a sidestand safety interlock that prevents the engine being started while the side stand is down, flip up the sidestand and try again to start it.

Additionally, to make sure the plug wire is securely fitted to the plug. It is possible that the inside of the plug wire cap has gathered moisture and may need to be wiped dry.

If none of the above suggestions solve the problem, remove the plug then reconnect it to the plug wire and hold it near the cylinder - but not near the plug hole in the cylinder head (fuel vapors) - while pressing the starter . You should see an obvious spark. No spark likely means the coil is faulty.

Hi,

Oil from the breather is an indicator of compression bypassing the rings. This causes sump compression.
Cause of the problem is worn rings.
You need to conduct a compression test, if the compression is low then rings are probably the cause of the bike not starting.

Remove and clean the carbs. Also clean the water trap on the petcock, (gas valve), if your bike has a water trap. Remember to balance and sync the carbs after installing.
