Xciting 500 / Re: Xciting 500 start problem. Stumped.

Here's the update...

New bank angle sensor arrived from Stadium Yamaha.  While I was waiting for delivery, I re-tested the voltage on the original part and discovered that I had previously been testing it incorrectly.  The part was fine.  So I moved on to the next likely culprit, the ignition control unit.  I swung by a local scooter shop, Kymco dealer, to see if they could test it.  No dice.  They had no diagnostics for it.  So I just ordered a new unit, clipped it in, and bingo.

Since I had all the panels off, I picked up some low voltage LED strips for $18 at an auto parts shop, wired them into the headlight and mounted them on the undercarriage (2 - 28" adhesive strips).  They look pretty cool and improve side-view visibility at night.  I may add a third strip to bump it up.  It's easy to get carried away on this sort of thing.

Thanks for the help and suggestions on this board.  I only missed one month and spent $160.  Not too bad.  And thanks to Stadium Yamaha for having the gumption to put their parts catalog online.  Very convenient.

Thanks Hoolander. I'm hopeful this is it but I could have blown the ignition coil and pump relay in the same moment.  Though, I don't know how.  The malfunction began when I lowered the side-stand to kill the engine.  At least I can eliminate this BAS idea.

I've been lucky enough to NOT lay it over so the sensor has never tripped before.  It's an important safety device, in the event of a nasty spill.  The people taking them off their bikes are complaining of losing power during wheelies.  I've had a hell of a time getting the front end up on the xciting, damn near took out a Pier One.

Placed an order 2 days ago.  Estimated delivery July, 14th.  I'll let you know, for sure.

I did manage to remove and open the bank angle sensor.  There's a pac-man shaped magnet that rotates on an axle.  At the top of the sensor is a small circuit chip.  It looks like it's designed so that the magnet will interfere with the circuitry when the sensor is tilted beyond 60 degrees on either side. 

To answer your question, yes.  I've put the sensor back in and tested. No luck.  Same behavior.  There's much discussion about disabling this part amongst the Honda CBR group but I think the Kymco sensor is a totally different part and I'm reluctant to try jumping the wires.  So I suppose the only way to proceed is replacement of the sensor, fingers crossed.

I have all panels off the bike and disconnected and reconnected every connector I can find.  If replacing the BAS doesn't work, then next suspect will be the ignition control unit. 

I'm learning as I go.  I appreciate all of the suggestions I've received.

Update:
There is no voltage reaching the fuel pump and there is no spark.

I verified the side-stand switch is functional and the engine kill switch is functional.  In testing the bank angle sensor, there appears to be a short on the black/blue terminal.  I removed this part and rattled it a bit and remounted. It still tests bad.  The black/white terminal shows 12.83 v while the black/blue shows 0.43 v.

Does anyone know how to bypass the bank angle sensor to verify that this is the faulty part?

The scooter sits in my garage for the Winter months, late November - late February. I've done well to avoid ethanol additives in gas.  I'm near 14,000 miles and have yet to replace the fuel filter, though it appears to be clean.

On replacing the spark plug I found the original to be fine.  Normal wear, not wet.

I'm fairly certain the fuel pump is not receiving power when the key is turned.  I need to verify this with a meter, but when I wired the pump directly with all fuel lines attached it primed for 5 or 6 "clicks" until it was pressurized.

I'm suffering from beautiful weather and a scooter that won't start.  Hoping that someone has some insight on the issue...

My 2007 Xciting 500 (carbureted) was running well the other day.  I stopped the engine by setting the side-stand.  Ten minutes later, I raised the side-stand and attempted to re-start the engine.  The starter cranks and the engine turns over but will not fire.  I behaves as though the side-stand is still down.

Since then I have done the following:
- confirmed my start procedure is correct
- checked all fuses
- filled with 93 octane gas, added sea foam
- replaced spark plug
- tested fuel pump by wiring directly
- boosted battery for faster starter rotation
- temporarily bypassed the side-stand kill switch
- changed oil (I was already dirty and running out of thing to do)

The biggest clue is that when turning the key to the first position, the fuel pump does not prime as it usually does.

Any help on this issue would be entirely appreciated.
