Well, i started with the simple things, checked fuses and checked for obvious wiring issues, checked for obvious loose wiring around the battery and fuse area, i unplugged all of my "bolt-ons" (TRE, Servo Buddy, Power commander V) moved from there to checking the kill switch and the side stand switch. someone had led me to the idea that fuel delivery might have been the problem so i pulled out the fuel pump and tore it down, cleaned it up really well. I don't feel that that is the issue however because if the pump wasn't pumping enough fuel or if the pickup screen was getting dirty, i do not believe that "CHEC" would appear on the dash. I pulled it apart and cleaned it anyway seeing as i needed some sort of accomplishment in my repairs lol
I did find where someone had duct taped a wire together at the ECM plug, it ended up being the ECM ground, i repaired that i and then searched for more similar "repairs" to fix. i have found multiple questionable wiring issues that i repaired on the spot such as a wire that looked like it might have been pinched for some time, loose plugs under the tank, i did search wiring from the nose to the ECM and along the way i opened up any spots that looked like they might have butt-connectors or plugs and checked them all for good, tight connections.
I checked the connections at the ECM, they were clean and tights, it doesnt look as this bike has seen weather hardly at all ever when im digging into it. all plugs have been clean, no corrosion, no bent pins, i replaced the sidestand relay/blinker flasher (this did fix my hyperflash from the LED's)
Yesterday, i did have a little more time to mess with it while acting up than i usually do.. i was on the side of a somewhat busier back road so i left the key on for lights while i waited for it to cool down, it seems that as it cools down, after about 5 or 6 minutes.. if your squatting next to the bike, you can hear the bike prime the fuel, the dash will go back to showing the temp rather than "CHEC" and then the FI light will come back on again, and after 15 to 20 seconds it'll do it again and again gradually cycling faster and faster. The bike wont start at this point, just crank... or if it does start, it will only run for 10-30 seconds and die.
Sorry about rambling on, I'm just trying to cover everything... Also, next i was going to start messing with the CKP sensor, I've read through some troubleshooting in the manual but it doesn't tell me anything else about it. (part #, location, replacement info) and I haven't had much luck finding one online. Any ideas on where i can find one?
Thanks again everyone for all the help!
