CBR issues

[racenrub]

Having a hard time getting a salvage bike to fire up, it's an 06 cbr600 looks like it was just the plastics that total'd it out. I've replaced the gas, checked over all the wiring and fuses and haven't found a problem that sticks out. The starter turns it over just fine when i have the charger on it's junk battery, but it just dosn't want to fire. Have any ideas for me? ............................Anyone know any good suspension starting points for a 180lb rider also.  Please and thank you.

Check the tip-over switch

[racenrub]

forgive the question here....but, is there actually a switch or just have to check wiring. Also this is on the left lower side of the bike correct also i just thought of it that i don't hear the fuel pump go when i turn the key on......i'm a motocrosser in a sportbike world.

The sensor is in the nose, just in front/below the gauges, between the head lights.  It should be plugged in (3 wire plug) and there's an arrow on it to make sure it's facing the correct way (round side down).  A little info on it here, as well as how to mount it directly to the stock fairing stay:  http://www.cbr600rr.com/forum/index.php/topic,19651.0.html

Also if you're not hearing you're fuel pump kick on with the key, also check the pump relay & the kill switch too.

As far as suspension - trash the stock shock & have the forks re-sprung for you're weight.  Stock springs on the 05/06 are good for about a 140lb rider...

That Dead battery isn't helping things either!

Side stand switches too.  All interrelated...

I was thinking about this and wanted to toss this out there: with the bikes I've had if the kick stand switch was causing the problem it wouldn't even allow the engine to turn over (for example on my 1st race bike I had my bypass for this switch fail while I was in a race and the bike completely died and wouldn't turn over the starter as a result), isn't that the same situation with a tip-over switch? Both of those devices are electronic disconnects so I figured they completely inhibited the ability of the bike to even engage the starter, unlike a mechanical device which could prohibit some unique feature of the engines operating system from functioning without effecting electronics. 

As for the problem I would 1st determine if it's fuel or electronics related, I would definately check and see if all your spark plugs are firing.

On my 2005 cbr the sidestand switch wouldn't let the bike turn over (but only if it was in gear) so in this case I think we can rule it out.  The bank angle sensor just kills the fuel so the bike will still crank.  Based on the report that fuel pump is not priming it is most likely the bank angle sensor or a fuse/relay in the pump circuit.  The bank angle sensor can be removed for trouble shooting purposes with a jumper wire shorted across the two outside wires IIRC.  Should be red/white to brown, been too long to remember the color code for sure, either way make sure you don't short to green/ground because you'll blow a fuse.  The key here sounds like the pump.  When you turn the switch on you should hear it prime while the gauges initialize.  Once you get that resolved I'd bet it will fire.

By the sounds of what jason has been telling me i'm bout 99% positive it'll b the TOS for the simple fact that it's missing due to the crash that made it a salvage bike    Plus i have no gauges at the moment so i guess i'll be buying both and see what happens then. thanks for everyones input

The bike will start without gauges and you can bypass the sensor.

sounds like you got it licked then. let us know if the problems continue... between Jason and myself we should be able to help you pretty well.

gauge is only useful to monitor oil pressure and temperature indicators.  That said I run the bike w/o gauge connected.

I'd highly recommend NOT to by pass the TOS unless you are planning to keep the bike rubber side down all the time.  It never happens to most of the people around here. If you lay the bike down and throttle gets stuck open , you will have to kiss your motor goodbye.

Also , make sure TOS is positioned vertically. I.e not tilted in any direction.

Pull the junk battery out and check it's resting voltage first thing, I doubt it's that given the fuel pump doesn't prime but lez check the silly stuff first hehe

Next thing to check is the interlocks (as suggested above) the tip over switch is normally located in the nose cone in nestled between the headlights (Bank Angle Sensor if you have the factory manual) and the bike will crank but not start if memory serves (as the fuel pump is disabled)  BAS is a half round and square black plastic sensor - find it, and if you don't have the upper fairing on the bike this is the most likely culprit (if you have the upper take the headlights out and in the top middle is the BAS which can be remounted to the fairing stay if you drill and tap 2 holes on the fangs that look like HOnda intended them for that use on the front of the fairing stay.

If that's not it I would point you at the engine kill switch next - get out the multi meter and check out the switch.

Kickstand interlock will only kill the bike in gear not neutral and there isn't a clutch interlock on a 03-06 cbr so as long as you are trying to start the bike in neutral it shouldn't be that

My bet is on a missing BAS tho

One other thought as I jsut caught hte rest of the post (lol) 600rr.net has a thread somewhere (I can't find it atm) on bypassing the BAS
