2002 CB600F No Spark

[Biker 1]

A friend just bought a stolen/recovered CB600F, 2002 plate.
It was missing the ignition barrel & had been dumped in a car park close to the scene of the theft.
He installed a new ignition barrel & battery. Bike is in reasonable condition: lights work, instrument cluster seems OK, wiring loom original/not messed with & appears in good condition. Starter motor spins up & sidestand switch seems to work. There is voltage to the coil packs, but no spark at the plugs.
My suspicion is the bank angle sensor, but I don't know much about these: do you need to reset them manually after the bike has been on its side? If so, how is this done? More to the point, where would it be located on this bike??
Hopefully I'm not barking up the wrong tree!

Thoughts??

Is it a bike with HISS?
If it is it could turn into a bit of a ball ache/ expensive.
Just a thought.

That was my thought as well

Not as far as I know - carbed bike, apparently with a regular key....

HISS was a late 90's feature so I'd think there's a real chance the bike has HISS.See here: https://global.honda/innovation/technology/motorcy...

I believe CBF didn't get an immobiliser until 07

It says it's a CB600F not a CBF600, so it should be a Hornet. Still I don't think they got HISS on a 2002 but possibly did in 2003 so worth checking that this 2002 reg bike is an F2 and not an early reg F3. If in doubt, is there a red light flashing on the clocks?

Not sure there's a bank angle sensor on the earlier carb bikes either.

Didn't these have a diode in the ignition as a crude anti-theft device or have I got that wrong?

Best bet would be to get your friend onto one of the very active Hornet Groups on Facebook and get the specific model knowledge from there.

Sorry I can't help more but never had a 600 Hornet, but am on the Facebook Groups.

Thanks all for the replies as ever!
I've looked at forums etc & there's a lot of stuff out there. Mate bought an aftermarket ignition barrel, apparently compatible with this bike, but I'm wondering if the diode is actually in it(???)
I'll make further enquiries over the weekend & report back....

Presumably he got a new set of keys with the barrel? If so then the immobiliser in the bike won't be coded to the chip in the key.

Best bet is to either buy a new CDI and matched keys, or contact a dealer who should be able to program new keys.

My 1999 cbr600 had hiss

I might be wrong, but I've had a few problems with the aftermarket ignition barrels on customers bikes before. They're often wired up to a generic scheme, if you check the function of the pins they frequently don't match up to the wiring diagram for the bike. So for example a barrel might be sold as fitting any ZX9R/ZX7R/ZXR400, except it can't, because they're all wired differently.

When you switch the ignition key to on, are you definitely getting a switched live going to the CDI unit to fire the coils, loom side of the ignition block connector? That'd be my first port of call, if you're not I'd suggest the ignition barrel might be wired up incorrectly.

If so, a quick workaround to test the theory is to put a little jumper wire from the ignition barrel switched live to the correct pin that should be sending power to the coils. If you get spark you've found the problem.

Hope that helps, and also makes sense

Thanks for the replies above.
Update: the bloke has installed a new ignition barrel (aftermarket), which apparently is a direct fit with electrical connector & wiring colours that seem to be correct. He then found a secondhand ECU & swapped that out - still no spark. There is voltage to the packs & all dash lights, warning lamps, indicators etc work as expected.

I thought I'd put it out there again, but I have a feeling he might need to send the bike to someone who actually knows what they're doing.....

Further update: it's definitely an F2 bike, so given the above advice, I assume no HISS
Bloody mystery bike electrics......

irrespective of the power at the coil, is it actually sparking when it's cranking? Does it smell of fuel in the exhaust pipe after a prolonged crank? Are the plugs wet??

if yes, it could be the fuel system or the HT leads are on the wrong plugs.

I had a CB400 of similar vintage and it had a weird vacuum operated petcock. If the petcock vac pipe isn't on the inlet it won't open the fuel flow

It's got 2 coil packs doing 2 spark plugs each, so no HT leads involved. Mate has taken out all 4 plugs including coil packs, & looked for sparks whilst cranking. Nothing. I'm sure it's an electronic issue & I'm usually ok at fault finding, but this time I'm stumped....

I know it's been mentioned before but the situation you describe sounds exactly like the way HISS is designed to work. I think you need to be 100% sure that the bike is or isn't fitted with HISS. If it is fitted with HISS you're currently on a hiding to nothing.

Bike has been confirmed as F2 version - poster above reckons these are non HISS & there are no markings to the contrary on the bike.

I'm not sure which "poster above" you mean as no one seems completely sure. I'd take the VIN to Honda and ask but it's your/your mates call.

^^^ pretty much this.

My old CB400 had H.I.S.S and without the correct key, this is exactly the issue I had. Carb'd bike with zero spark.

Put the correct HISS key in the ignition and bingo, ran like a top

Jesus . It’s not hard to know if it’s hiss or not. If it is it will have a bigger key and plastic hear the lock with hiss written on it.
Probably got an alarm ripped out of it, or the thieves have mucked with something.
I’m in south London with 20+ years of experience if you want it fixed.
