Hey guys recently ive had a problem with my 600RR, I bought it rode it for about 500 miles from the point of sale to home, rode it in town for about 30 miles, after which bike started cutting off. First time it cut off I push started it and made it home, second time it was jerking between what seemed like closed throttle and open throttle, next it wouldn't start at all like a dead battery but the next day it started fine I rode it to work, when I left work it cut off leaving the parking lot after which id would start for a couple of seconds and die. I suspected rectifier which I changed, next I went to the dealer which told me it was the ecu, I also replaced the ecu and nothing, it wont even start now. I just checked today and it has no spark, what could cause this? Ive been working on my own bikes for over 10 years and im stomped by this issue. Also could you guys show me the links to the kickstand bypass and BAS bypass for the 2010 I can only seem to find them for the earlier models.

Thank you in advance!

Main issues to look at Fuel pump ( does it prime when you turn the key on or not )
If not it can be BAS sensor , Fuel pump relay , Kill switch , blow fuse

The battery (condition ) get it load tested to see if it can hold a charge or not weak battery can cause all kinds of issues just because the lights work does not mean its a healthy battery

Fuel pump primes, I believe im getting fuel down the cylinders, I know that I am not getting spark because I took one coil out and put a spark plug in it with no spark coming out of it when grounded.

Battery was low from sitting but ill try again tonight with fresh battery. I also have never heard of the coils going bad, not suddenly and for sure not all together.

Get the battery fully charged then load test it hopefully it will pass the test when attempting to start the bike take the head lights fuse to avoid giving away battery juce & start the bike
Do not roll on and off the throttle as that will foul the plugs hold the throttle wide open yes wide open that will not foul the plugs & usually that process works with hard to start bikes

The bas or kickstand wouldnt be at fault since my fuel pump is still priming correct?
That is correct you know its not a fuel issue , battery issue ( possible ) elecrtical issue ( possible) as well the battery is easy to detect charge it them load test it if it passes then its electrical some where probably in your connections that is why the shop maunal is a must have tool in your case as there is too much to go over just take one thing at a time i got faith you will find out the culprit and get the bike started

Could it be the crank position sensor?
Very possible there was a couple of trouble shooting threads that were fixed due connection issues of cranck position sesnor wibbly dealt with that before from what i remember pm him he got the knowledge to help you out and won't mind sharing it link to his profile http://www.600rr.net/vb/member.php?u=101473

I looked through Wibbly's started threads but found nothing about bike problems. Another question while im at work and thoughts of fixing my bike are rushing through my mind, could it be flooded, what would be the start up procedure for that, since ive started it so many times with no success it could be a possibility.

Wibbly did not post a trouble shooting thread on the contrary he shared his valuable knowledge in a bunch of them & that is where i got the info i mentioned . As far as flooded spark plugs you can simply remove them from the bike clean them then reinstall them i have also had luck just letting the bike sit for a few hours before attempting the restarting process for some odd reason the RR is not a bike that likes to sit unused for a while
