OoPEZoO Posted May 19, 2007 Share Posted May 19, 2007 The guys all headed out for a ride this morning at the MAYhem. Danielle and I decided to head for skyline drive to take in some relaxed rideing and nice views. Well......we made it about 100 yards and something broke. I'm on my way out now to take a closer look, but I was heading for the gas station on the next block and the bike just coughed and shut off. The starter will crank just fine but won't start. I tried to push start it by popping the clutch, but that won't work either. Of course I left my manual at home, and the rest of the guys are out enjoying the country side. If anyone out there can lend a hand or feels like stopping by to watch me scratch my head in the parking lot, I'm at the Hampton Inn 1655 Apple Blossom Drive Winchester, VA 22601 If anyone has any words of wisdom, my phone number is 717-615-7420 -Keith Link to comment
bobbybob Posted May 19, 2007 Share Posted May 19, 2007 I know this is rather obvious, but since you were heading for gas, I assume you need gas. Rather than trust the gauge, go ahead and bring some gas and insure it DOES have sufficient fuel. No warning lights flashing? Link to comment
outpost22 Posted May 19, 2007 Share Posted May 19, 2007 Is it possible that your side stand switch is either in an "open" state, or that the side stand is partially lowered? Check to make sure there IS gas? How about checking the battery ground? Or is it raining and it shorted out your HES? Link to comment
OoPEZoO Posted May 19, 2007 Author Share Posted May 19, 2007 Bike is all fixed.....it was the HES Link to comment
AndyT Posted May 19, 2007 Share Posted May 19, 2007 What did you have to do to fix the HES? How hard a job was it? Inquiring minds want to know? AndyT Link to comment
ChrisNYC Posted May 19, 2007 Share Posted May 19, 2007 Holy crap, we were just talking about the HES last night ... I'm starting to get paranoid that I should carry a spare HES on the bike ... Glad you're back on the road! and it was nice to meet you (two!) ------------------ Chris (aka Tender Vittles ) Little '77 KZ400 in the Big Apple Black '99 RT for Everywhere Else, such as ...

kruuuzn Posted May 19, 2007 Share Posted May 19, 2007 Okay, okay, I'm gonna risk looking foolish here but WHAT is HES? Link to comment
Green RT Posted May 20, 2007 Share Posted May 20, 2007 Okay, okay, I'm gonna risk looking foolish here but WHAT is HES? There are no foolish questions. HES = Hall Effect Sensors. Two magnetic switches located on each side of the front end of the crankshaft. They open when near a piece of metal and close when not (or visa versa). They sense the rotation angle of the crankshaft and transmit that info to the computer which then decides when to fire the plugs. Link to comment
ESokoloff Posted May 20, 2007 Share Posted May 20, 2007 The Hall Effect Sensor provides the Motronic (bikes brain) a crank shaft position for timing. From this input the Motronic provides fuel & spark at the proper times. The sensor does not fail but rather the insulation on the wires harden then crack/disintegrate causing the signal(s) to short out. Rain or a bike wash exacerbating the situation. My understanding is that about the time the 1150's came around, BMW upgraded the wire insulation & this is no longer an issue on these & later models. Edit: Figures some one like Will would pop in & respond faster then I can peck at this keyboard Link to comment
boatzo Posted May 20, 2007 Share Posted May 20, 2007 Thanks for the info on this. I still want to know what OoP did to fix his problem. I just wish I could remember all this good stuff that comes across this board. Link to comment
OoPEZoO Posted May 20, 2007 Author Share Posted May 20, 2007 I'm going to post up a different thread with how I fixed the bike. Mainly for the sake future searches......and also because the couple who helped me (Greg and Candi) need a big thank you for going so far out of the way to help someone they knew for about 5 minutes.
