CBR 600 cutting out

[Guest]

i was riding today and my bike just died on me thought it was battery its showing 12.65 volts but when i got it started again it was showing 11.2 volts could this be the regulator i need to change it kept dieing when i opened the throttle can anyone help please thank you

Definitely something on the charging system.

Reg/rec would be the first thing to check, then alternator, then (as we found out the costly way ) all the wiring and connections between the three.

Take the plug off the reg/rec and check AC voltage across all the pairs of incoming wires from the reg/rec when the bike's running. If there's power getting that far it's reg/rec or the wires/connections there.

After buying 2 reg/recs and pricing up an entire wiring loom for cat's R6 we found out it was the white connector block that plugs into the reg/rec, an entire £1.50 piece

also check continuity on the red from the reg rec plug to the battery ( probably to/from the main fuse/starter relay..check your wiring diagrams if you have a manual), clean and grease the terminals in the plugs...if the ac output from the generator is fine , and everything above the reg rec is ok, then its probably the unit itself

A mod on my Blade is to add another earth wire from the reg/rec connector block directly to the battery negative terminal.

Do it with the positive too

With the bike been a Honda its more then likely the reg rec that's gone test it first though and check wiring

ive now got the regulator fitted but still have the problem managed to get it started but when I touch the throttle it just dies do you think I should change the alternator not sure what to do now ?

time to do some testing!

have you got a multimeter? and whats your location? someone could be close by to help

[Tango]

Fuel Starvation?......is the fuel tap OK?......do you have a fuel filter in-line....and is it OK? Plenty of fuel in the tank?

[littlecat]

check the wiring, charge the battery, and made sure there not a fuelling problem.

if you havnt got one , buy a multimeter, saves a shit load of expense replacing parts that arent knackered

[Tango]

A couple of quid on a simple multimeter can save you pounds......

Surely its got to be a fuel problem as the only thing that alters when you open the throttle is the demand for fuel?...It doesnt alter the spark etc?

If this were a normaly aspirated engine, eg carbs, then it would be the symptom of a blocked jet...

it alters the load which in turn will kill a weak spark if the battery isnt charging the battery voltage could be too low to allow any load on the engine

[acting_strange]

It still sounds like a pilot jet or a pipe off allowing too much air into the mixture...

[Fozzie]

It does sound like that

But as the voltage reading is off (given mine reads 13v when charging, anything over 14.5 or below 12v and its knackered).

CBR600's have a know reg/rec fault. Always worth swapping it for an aftermarket one anyway.

[oslin06]

check for an air leak i.e. vacuum pipe off or split rubbers on the carbs or the rubber blanks missing on the top of the carbs.

Thanks for all the advice it turned out to be the connector on the fuel pump that went i cut the connector off and put new one on its working sweet now thanks again

[Tango]

Glad you got it sorted out mate.......I thought it sounded like fuelling of some description......
