If the starter is turning, that rules out the interlocks on the clutch & sidestand.
Next step is fuel: turn the petcock to PRIME, wait 15-20 seconds, then back to ON. Sometimes a hot run will evaporate all the fuel out of the carb bowls after you park the bike; switching the petcock to PRI temporarily will refill them. If this works, great, if not, then we need to go on (I do the PRI trick first because it doesn't require removing any parts from the bike).
If the plugs are firing (arsenic's advice and the next obvious step), then reinstall them. If they're not firing reliably, replace them. Katana's are harder on plugs than most bikes and all cars. While you are in there, it's time to check the fuel and vacuum lines to the petcock and at the carbs -- make sure they're not kinked nor cracked.
Try firing it up again. Still no joy? Time to pull out the air filter and check it, as well as clean & check the inside of the airbox (which should be basically clean or coated only with a very light coat of oil). Make sure the drain tube for the airbox is installed correctly as well & plugged off.
Try it again... Still no joy?
Well, then it's down to suspect quality fuel or water in the carbs -- drain the carbs, refill them from a known-good fresh fuel source and try it again.
well, no spark which, I figured was the problem, could be many, many things. Start at the plugs and eork your way to the CDI.
- check the ohm resistance at the coils
- check the ohm resistance at the signal generator
- check the harness for breaks between the generator and CDI
- check the CDI
If you don't have one, your gonna need a manual, you can download one for free here.
+1, that aint right, there's a problem some where and if you had no spark then spark, that could point in the direction of the CDI, intermittent failures are a common thing when a CDI is going out.
I'm guessing that he didn't test spark the right way (just a suspicion -- no insult intended), not grounding the plug properly... While it could be the CDi, unless the CDi was physically damaged or static-damaged, it's very unlikely to be the culprit.
Yes I didnt do something right so I started over with you guys advice. And now my kat is purring again. Thanks guys. You did your country a good deed and helped a soldier. Thanks guys. So with it wanting to die on me what is that?
Its the KatScout! Scoutin' for over 6 years! Scouts OUT!
does it still want to die on you? Turn the idle up to were it's supposed to be. Left side of the carbs, when your sitting on the bike put you left hand down and it's right there. It's a Phillips head screw that meant to be turned by hand. If that doesn't help, you have some dirty carbs. Blocked pilot circuit, tear them apart, if your confident in your mechanical abilities, and clean every passage with carb cleaner and compressed air.
