I dont have starting fluid but i sprayed a bit of wd40 in there as someone told me that would start it it still didnt start. The starter motor works fine everything turns inside. The fuel and oil are new and everything has been cleaned. The engine has been rebuilt. Is it possible if my stator was damaged it could cause the bike to not start

Hello i swapped the carbs over and still wont star but this time i now have no spark i am sure it is something to do with the alternator/stator

i'm no expert (in anything)

But the stator/alternator is only useful because it takes the spinning engine, some magnets and some wire and makes it into electricity that it can pass back to the battery to charge it up. (I think that's pretty much how it works... might be some magic involved too)

As such - i don't know a faulty stator - or even no stator would stop your engine from running...

You need fuel, air and a spark. All at the right time.
If one of them's missing - you won't get a running bike. Don't stress about the stator until it's running and then the battery goes flat.

Check fuel is getting to carb. check carb. check spark. Then worry about timing... that's where i'd be looking

Fit the correct powerband. Your machine has obviously been fitted with a red one. You need a pink headed one. Turn it on and run it up and down gently for a few minutes. Increase your revs gradually, and you will come to a great result.

Hello the tool for the flywheel removal was the wrong one so got to get them to send right one out. I used starter fluid today and it was still turning and the odd time it would try to start for half a second if that any advice

So after blaming the stator for not producing a spark, you're removing the fly wheel?

In that case, I'm out of ideas as to what it could be Confused

Searches thread for "meter".

Not found.

Keep guessing, OP. If you throw another few hundred quid of random parts at it, might get lucky.

Whatever you do, do not invest £5 or ten minutes in actually diagnosing your problems. Where's the fun in that?

I only guessed it my be the stator as im running out of things it could be. I also dont know a massive about bikes and just wanted some help

Stop guessing.

Spend £5 on a multimeter.

Invest 10 minutes in watching YouTube vidoes on how to use it.

You can now follow one of the many, many, many guides on Google it diagnosing motorcycle electrical problems.

I have a multi meter and know how to use it

I know its not electrical faults as they have just recently been on a previous bike

zark · Trackday Trickster Joined: 18 Dec 2013 Karma :

So the components may not be faulty... What about the connections and wires joining them together? A meter will help here
