2008 R6 Won't Start
Hi All, Long story.
I had a crash in Feb at the track and am reassembling my R6.
Finally got it to a state where I could start it about 1 month ago. It started and ran well for about 15mins. Put it away and started fitting up the fairings etc over the next few weeks.
Got them fitted up roughly 2 weeks later. This time after I started the number 4 cylinder was not running. So I pulled the spark plugs and coils. I figured maybe the number 4 was fouled. I replaced all the spark plugs anyway and she still only ran on 3 cylinders. The removed plugs didn't look too bad.
So then I pulled the number 3 & 4 coils gave them both a good clean with electrical cleaner and and tested their resistance. Both tested the same. I swapped them around and reinstalled to see if the problem would move to #3 cylinder. This time when I went to start the bike I got power the dash lit up, fuel pump primed, fuel rail primed. When I hit the starter there was a very short turn of the starter motor then nothing. So then I pulled everything apart again and double checked all connections from the coils right down back to tank connections. Everything you touch to get into the coils and plugs from the tank side.
I thought maybe my Speedcell wasn't working as it is one of the 2.5ah ones. So I put in the Yuasa spec battery from my MV (which is the same spec as the R6). Same thing. Dash lights up, fuel rail and pump primes, hit the starter I can hear current being drawn but not starter motor action.
I have checked and the only error fault from the on board diag was the lean angle sensor, which I reset. The bike had been running fine with that fault on the when I started it 1 month ago and when on 3 cylinders. I cleared it anyway. That faul has not come back and no other faults are evident.
Can some one give me some pointers for a suitable list of actions?
I'm busy with work and family for a week now, but when I get back to it I'm going to start with:
Cut off relay
I think I have checked everything I have touched to change the plugs. But I'm humble enough to admit I may have pucked something. So any help from the experienced spanners on here would be appreciated.
