Default Just In Need Of Some Input

I changed the R/R about 4 months back because it didnt crank and that fixed the problem.
About 2 months ago, a new problem, this time it cranked but wouldnt turn so I ordered a new stator. Upon trying to change the stator, I opened up the wrong side and had to order a new clutch gasket. So finally, I installed the new clutch gasket, installed a new stator, even soldered the wires to the stator as what the manufacturer recommended and still it would crank but no turn. Checked the CPS resistance, its good. Checked battery voltage, good. So now Im thinking spark plugs?

You 2 cents are appreciated.

Oh man... The bike does not need a stator to run as long as it has a strong battery. It won't run long, but it doesn't need it. Sorry you just tossed a fist full of money down the drain.

Now on to your problem. You only need four things to make a motor run"
Fuel, air, ignition, and compression.

Fuel:
do you have gas in the tank? is the pump priming when you turn the key on?

Air:
is your filter clean? this is a minor issue, because it would have to be wrecked to not start. It will run poorly, but should normally start. Check it anyway.

Ignition:
Do you have a spark on all three cylinders?

"Yes I do!" Are the plugs good?

"No I don't". Figure out why. Check the connections, check the fall switch, check TuneECU for error codes. Is your kick stand safety switch working? Is the clutch safety switch working?

It's normally something very simple.

Thanks very much for your reply. I figured probably wasted money by getting the stator once it didnt start after installation. I'll check those other things you mentioned and see if I can narrow it down some more.

The fuel pump does make that noise when I turn the key so Im guessing its not that. Gas is in tank also.
Up next sill be the spark plugs. How do you reckon I check spark?

Thanks again.

You have a few ways to test for spark. The fastest way, but not the safest, nor most accurate: Pull the plug out pop it back into the plug receptacle (the boot you pulled off to get to the plug). Hold the plug end about 2mm off the top of the head bolt. With the bike in neutral, and the clutch leaver held in (use tape, zip tie, or a friend) crank the motor. If you see a spark jump to the motor, it is working.

You can also buy inexpensive testers at Harbor Freight, or most any auto store. Follow the instructions.

Good luck.

Since you'll be yanking plugs anyway, try to start it before pulling them, then check to see if they are wet. If they're dry, it indicates that no fuel is going into the cylinders.

Ok will do. Hopefully by Monday ill get to do everything. I'm thinking just go ahead and buy spark plugs and replace them to rule that out.

Good call madmel. I would disassemble everything first though. By the time you got everything off it could dry out otherwise. Leave the plugs, but reconnect the tank with the air box off.

Of course, cranking for 20 seconds with your nose in the tail would inform of gas delivery too, but could not tell you if only one injector is malfunctioning.

I would just because you are getting into it, but remember to check for spark on each one.

Good luck.
WARNING: buy the inexpensive tester. A friend of mine checked a plug by removing it from engine, and grounding to the head. When he turned the engine over compression forced gas out of the sparkplug hole onto him. The plug proved to be good, because it sparked, igniting the gas coming out of the sparkplug hole and setting my friend on fire. He was burnt pretty bad before we could get the fire extinguished. Freak accident but still. If you use this method, stand well to the side while checking to see the spark.
