Cutting out higher rpm?

I have rode the bike several times this year. Brand new battery. When I got it out today ran fine for ten minutes then the tac headlight running and brake lights went out and bike began to run very poorly in higher Rpms couldn't run above 30 mph. Could this be stator or what? Please help thanks !

Sorry about your trouble, but somebody here help you through.

Its either the stator or the RR more than likely. First off, do the stator wires look like they've gotten hot? Any melting or charring? Its easy to check the voltage at the stator wires with a voltmeter. Check (on AC mode) between each of the legs while the motorcycle is running (disconnect them from the RR). If you've got good voltage there its probably the RR. You can also check the impedance between each leg as well as grounded legs while the engine is off.

I guess there is also the possibility of a bad battery? But if it seems to charge OK thats probably not the problem. Running for about 10 minutes seems about how long it might take to drain it running without the charging system working.

Difficult to start the engine after riding.

Dear Guys,

I am using a kawasaki VN750, US Spec, manufactured in 1997. Really need some advise.

Every time after I rode my VN750 for a while, and after I off the engine, I can't easily start it again. I have to wait for several moment in order to get the engine started. Is this a common problem for VN750? For info, the battery was just replaced on last 2 mths.

Is there any method to mitigate this problem?

Thanks a lot guys.

Yes. Get an AGM battery..... Then look for the post on adjusting the pickup coils.

Think that last one was spam, no?

kinda sounds like it but it seems to straight forward of a question, so just in case it wasn't. get ngk iridium plugs with the agm battery!

Thank you for the help. I do not believe it is the battery or charging system because the bike has been started several times after being rode after the problem, so the battery is staying charged. Where are the wires coming from the stator? I unfortunately had to leave my bike where I attend College and I am back at home. But could please go into further detail as to how to check the voltage of stator and rr? us the rr you referring to like a selinoid or ? sorry not extremely familiar with electrical system and the terms

If the battery is staying charged it is not your stator then. I was under the impression that the battery was dying in the process of riding after 10 minutes.

Someone else will chime in with an idea. Seems like I have read posts of ignition switch problems causing problems like this. Try a few searches on that topic.

Also, do a search for TOC to get a manual in PDF form. This will guide you through testing the stator and what impedance values should be.

Thank you. Yes the battery is staying charge so Rhys good that that means it's not the stator at least. Thanks for the response
