For those who may have similar issue: It was the cam/timing or crank Positioning Sensor/revolution number sensor.

For those that may have similar problem: Took it to the Duc Shop, it was the cam/timing sensor.

Group: Is the Revolution Number Sensor (#34 on the wiring schematic), a crank positioning sensor, and a Engine Crank Phase Sensor the same.

I also tried swapping the ecu's around with same results.

I get a constant 11 & 10.7v from plug wires.

Thanks for the replies, Derek: There should be a repeating spark while the engine turns over. There's not. Tried leaving the plug out, attached to plug wire and starting w/ kill switch in run position. Outcome w/ two different types of brand new plugs: No cyclic spark, only one spark after releasing...

Thanks for all the previous suggestion regarding no spark issues. Hoping for current issue suggestions: Bike started, rode for 15 minutes, parked, afterward turned off/on fine. Next Day: No spark, removed relays, replaced relays, started. Next Day: Spark but doesn't start ---- What I've tried: I pul...

I saw on another post that one of the relays controls the injectors, so I used voltmeter to test relay, through prong 86 & 86 I get 85 ohms and on the other I get 108. Is this a potential problem?

? I messed with it today & now I have spark at the plugs (I don't know what fixed it) but no fire. I tried ether in the intake, in the case there is no gas flow, no fire. I'm almost positive I didn't have spark before as I put my finger on the plug (while starting and kill switch on) and no shoc...

Starting to think it's the outside temperature, as Bomber says his would start but the vibration kept his going, but mine will cut-off and cut-on fine.

If I take the fuse out on the two relays & test with voltmeter I have almost 12 volts. Does this mean they are working ok?

Problem occurs again :( Rode it yesterday - went out today to start it and no spark. I fiddled w/ the relays (again, which 'fixed' it last time) and nothing. I noticed a little acidic green stuff around the insertion point of the relay. I'm going to see if auto parts store has something I can spray ...

Thanks for the support & ideas: I pulled the two relays out & spoke to them softly, put them back in their home and the bike fired up in about 1.5 seconds and runs great - I think the new plugs helped too (w/ the start up efficiency). Replaced the fork seals (took me 3 purchases to get the c...

Thanks Nickta - yes, no spark in both plugs. Is (28) Turn Flashing of the schematic (P.79, workshop manual) solely for the turn signals? Found a post very similar to my problem. In the post, the problem is found to be in the relay modules which are on the upper-left-front of the bike. I'll play w/ t...

Hey paso; I thought about that (it may be a faulty kill switch), but the fuel pump cycles and it doesn't cycle w/ the kill switch in the off position. So, no - it wasn't in the off position. I don't know if this helps or not, but some added info: I use a little starting fluid to try & start it -...

Hey guys: Spring here; fired the bike up about 4 days ago, ran fine. Tried this morning and there's no spark at the plugs (new). I checked the fuses in the modules on the top left front of the bike (I don't know what it's called), checked the fuses near the brain, checked the solenoid, all good; fue...
