Hi, Ironhorsedave if you have a CKP sensor it needs compression to send the correct signal to the ICM/ECM, make sure both spark plugs are in heads and use a grounded third plug to check for spark or hold spark plug cable close to spark plug in the head. If still not getting spark the usual suspects are:
1. Fouled spark plugs.
2. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Loose connection at ignition coil or plug between ignition sensor and module.
4. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose.
5. Faulty ignition coil or ignition / electronic module
6. Failed CKP, CMP, or BAS sensor.
7. Faulty ignition switch.
8. Security alarm failing to disarm needs reset

. The relay is attached to relay connector located to the right of
the battery underneath the seat.
Pull relay from relay block.
. Connect positive battery lead to the 86 terminal.
. Connect negative battery lead to the 85 terminal to
energize relay.
. Check for continuity between the 30 and 87 terminals.
A good relay shows continuity (continuity tester
lamp “on” or a zero ohm reading on the ohmmeter).

SOURCE: 2002 buell blast is running rough - missing - backfiring

Wow, my 2002 blast is doing the same thing, or at least it was untill it blew a hole through the exhaust and quit running all together. Time for a sportster.

If your bikw is backfiring it means that the timing is off. When an engine backfires it means that the exhaust valves are opening too soon. when that happens they are partially or all the way open when the air/ fuel mix is ignited in the cylinder. Check the wiring leaving the flasher relay to make sure that there are no breaks. Sometimes there is also a seperate fuse that runs inline with the relay to protect it so make sure that if there is a seperate fuse that it is ok. The relay part number that I came accross is ZZ38170. When i searched for your vehicle it said that it was a 4 prong flasher and this came up many times.

How do I cure vapor lock?


If you're getting vapor lock, the bike will die after a few miles, and not restart for several minutes.
If the bike dies, immediately remove the gas cap and see if the bike will restart right away.
You could also ride it without the gas cap (try it on a tank that's 1/4-1/2 full, NOT fully full, because of gas splash) and see if it doesn't die after a few miles.

More likely to be your ignition coils. They heat up and expand this can cause an open circuit which will close up again when it has cooled down. Although, a bad charging system may cause this problem. Check the battery voltage with engine switched off ( approx 12 volts) and with the engine running (approx 14 volts) If you are getting 14 volts then your battery is dead, if you aren't, then your charging system has a fault.

I have an 05 with the same problem. Sounds like your STVA went out. Do you still have your butterflies wired open? I know how to repair the stva fixed mine, and saved hundreds....if your still on this post email me so we can get our bikes fixed. also check your kick stand sensor! This can malfunction and cause same stalling problems.

97 gsxr dies during short rides and wont restart for 8-25 minutes


Check the fuel filter and petcock screen in the bottom of the tank. If either is dirty it will cause what you describe.

Instrument Cluster needles stuck -- Electrical Problems


Needles stuck indicative of instrument cluster complete failure. Cause unknown. This is second instrument cluster that has failed on this bike, first one failed at about 3000 miles, twenty-two months ago. This "new" one died in mid May 2008. Received word from Ducati North America that they will accept the warranty claim for the toasted instrument cluster!!! Am still concerned about cause...this is second instrument cluster for this S2R800. Seems to be an issue prevalent on some of these late model Monsters. Will update more after instrument cluster gets in and replaced by Bloodworth Ducati in Nashville.
