1994 cbr 900rr fireblade troubles ...

Hello, I recently acquired a 94 cbr900rr off of Craigslist that "Only needs a stator and battery".

The bike was dropped off at night and at a glance, looked great! So, I threw it on a trickle charger and waited. Next day I went to fire it up and it just cranks ... No fire.

Closer inspection I saw every fairing piece is cracked ... So currently naked thinking it would give me more room to work on it.

I'm getting to the point I'm pretty stumped. Any help would be greatly appreciated.

3 basic questions to ask:

Does it have gas? Is gas getting to the motor? Does it have spark?

Yes it has fuel, petcock is broken so not exactly sure what position it's in, I smell fuel and I've tried starting fluid in carbs ... So yes to fuel to motor.

Having a difficult time getting to the spark plug boots to remove and check for spark. It did puff out a flame a little bit ago while I was turning it over, so I'm guessing there is spark ... it has acted like it's backfiring a couple times, but mostly just cranking.

I checked firing order ... facing handlebars from rear of bike, left to right on engine 1,2,3,4 (labeled on valve cover) and coil on left side position towards seat is 2 above that is 3. On right side, closer to seat is 1 and upper is 4.

Choke up (but it slides in by itself, so I have to hold it). Trans in neutral. Have had kickstand down and up (no change) and clutch in and out (no change).

There's a rubber cover on the choke knob mounting bracket. Under it is a black plastic nut that you can tighten a little to get the choke to hold. Don't overdo it.

Might be that one of the cutout switches is misbehaving. You might try bypassing the kickstand switch. Also, have you checked fuses yet?

Checked fuses at the fuse box on the front of the bike. Haven't seen any other fuses ... there are a couple I saw for the power source on hid units ... are there other fuse locations?

I've stripped the bike of all it's fairing bits to allow for better access.

I'm uncertain of how long sinc ethos last ran ... the Craigslist seller has been less than forthcoming with Info. Other than he swears it runs.

Have you pulled the plugs to see if they are wet?

Do you hear the fuel pump when you first turn it on? Sounds like the plug wires are in the right order. Not starting with starting fluid would seem to imply that there is not good spark. You really need to determine if the plugs are sparking consistently before you bother with anything else. That said, I bet the carb passages are full of gunk too.

My inclination would be to pull and clean the carbs, replace the plugs, check the stator and replace if necessary, and also check all the cutout switches and relays and also the R/R.

Hey there guys, quick update ... motobiker stopped in today and helped me do some checking ... fuel pump works (but does not come on with key), carbs seemed to be ok ... fuel drained out was looking good, he said it seems to be getting into a flooding situation. We were going to pull plugs to check spark, but neither of us had the correct spark plug wrench.

I'm just getting home so I'll be looking on Amazon prime for a tool kit for this bike ... as soon as i can get plugs out, ill update on spark.

Going to get new plugs while I'm at it ... Any recommendations as to brand, temp etc?

Thanks for all the questions and input. I've never had to do any real work on any of my bikes ... the information and processes are great. I'm already learning much about this bike. Can't wait to have it up and running.

Buy or download a Factory Service Manual. It will be invaluable and answer many of your questions. Can't go wrong with NGK or Nippondenso plugs Manufacturers recommended heat range. I'm actually running some E3's in my bike now.

I'd suggest pulling plugs one at a time, checking spark at each one and putting it back in before changing any of them out. I spend my days helping people with troubleshooting electronics. There is often a desire to "swap such and such part out while I'm in there checking things". This usually leads to the device still not working and a now more complicated puzzle to figure out. Test all the original plugs first before you change any of them. Then if one is not sparking, go back and swap in a fresh plug on that one cylinder and check for spark again. If it's still not sparking you know it's not the plug and you can begin to investigate the wires and coils.

If I was a gambling man I'd go long odds on this one and bet that it ends up being gunky carbs even though you smell fuel. But you have to make sure you have spark before you check anything else.

I might have a plug socket that will fit. I have done the plugs on my CBR600F, so I must have a socket in the tool chest that got them out. Don't know if the 900 uses the same style plug, but it's quite possible.

If your pump is working when jumpered but not functioning when key is on check your fuel cut relay... Notorious for problems.

Also do a fuel flow test to make sure the pump seals aren't starting to go.

Chances are that's all that's wrong with it.

Those relays tend to be spendy

I don't recall the fuel pump on my 93 cbr900 or 96 vfr750 priming with key on. You had to be actively cranking or the engine had to be running for the fuel pump to be running.

Carb clean/rebuild. It's been sitting and the carb O-rings are probably the 22yr old originals and need replacing
