So, I spent all day working on my bud's 05 636. Little things like bleeding brakes, new clutch and brake lever, new air filter, blah blah. The bike ran fine every time it was started no problem all day. As we were finishing up he wanted to take it out for a test run. He started it and it ran fine for about 3 minutes and dies out. We then could not get it to start again. I figured maybe the battery died out since the bike sat for a while. (Mind you that was a long sit for all I know, this is a 2005 with only 989 original miles on the bike). I put a voltmeter on the battery and got a reading of 12.20 volts. Steady reading no jumping around. I figured I'd put it on my 1 amp trickle charge anyhow. The bike used to flash the FI light at me when trying to start and then click as if the battery was low. Now, the FI light does not come on, no clicks and an extremely strong crank. I took the fuel pump out of the tank to be sure it worked and shot fuel out of the metal line which it did just fine. No fix.
Now some background on the bike, he bought it from some backwoods asshole who took the muffler off and has been pretty much running it straight piped for idk how long. I am hoping for his sake it did not kill the engine. I cannot figure out how an 05 has only 989 miles on it. 1000 miles is usually the break in point on these bikes if I remember correctly, so I highly doubt this guy broke it i n properly. I know this could be a number of things that cannot be answered without the bike in front of them, but maybe some past experience with a similar issue may be of help. The kid who owns the bike is going to buy a new battery tomorrow morning to rule that problem out. I am going to go through some of the wiring to see if anything shorted out or maybe a connection got broken. Oh and the battery never died but the clock on the gauge reset itself, now I am thinking it is the ECU
