RC dash, do you need it?

I am sure someone knows... But why not just unplug it and find out?

Why are you wanting to get rid of the dash?

Well, my bike dosent have any spark, the tach signal per the manual is supose to be 10v peak, im getting 5v from the dash, the service manual dosent label the the connector at the dash, so im not sure which wire does what? I was thinking that if the oil pressure indicator circuite in the dash is not working right, maybe it would effect the ecu somehow.
I know the ecu is good, i tried it the other day in a friends RC, it worked.
Very strange problem, no spark, cam/ipg has signal going to the ecu, converter is good, bike will prime like normal, and injectors will pre-fire for start-up, there are no fault codes, tried shorting out the (2) kick/clutch inputs to the ecu. tried looking for bad grounds with my DVM.
still no spark.

no dash needed

If you mean the speed-o as the "dash" i can personally testify that I have a 2000 and it does start without anything resembling the dash. I am afraid the cooling system won't work so I only run it for a very short time.

You mean the fans right? I'm going to be starting my bike without the instrument cluster very soon so that is good to know.

Ok, nice. Thanks guys for the info..

Ok, i think i figured it out, the bike for some reason never gave a code when the bike died, and whenever i was working on it i cranked the engine over for less than 10 seconds "with no plugs" and with no codes being present. Well, I heard that the bike in some cases needs to crank over for more than 10 seconds to give a code. I cranked it for 13 seconds and a CODE 18 CAME UP "CAM SENSOR", also from what i gather these cam sensors that are on the RC51's are also used on Honda Accord automatic transmissions as speed sensors, PN-28810-P7Z-004. $70 from the local Honda dealer/Parts dept.

If they are common part they can probably be had from napa/o'reily or any other auto parts store. Trans sensors are normally a stocking item and would be cheaper than from a stealership

No you dont need the dash. Running with out it will not affect the cooling system and it will not set any codes. The only problem you may have is you wont know what temp the bike is running at or if you did have any codes unless you added a temp gauge and a MIL light.

Thanks for all the help guys, i did replace the cam sensor with a new one from the Honda dealer with the code being reported again. I poped off the valve cover and found the intake cam cap was broken in 2 places, and the cam was advanced 3 teeth, so all the electronics was fine, it was the cam position signal that was not right, not the electronics.
