How common is it for stators to go out?

Hi everyone, newbie here. My dad and me are thinking about getting a Vulcan 700/750. our last old bike was a Honda CX 500 that was interesting to say the least.

Ive some stuff on here about stator issues and was wondering how common it is to need to replace the stator? Ive read on here it seems like a pain if it does need replacing, and after the CX500 which needed it replaced we do not want to go through that again.

thanks for any info

Every bike will need a stator replace at one time or another.
How you take care of the bike and what extras you add to the bike.
You hear about them here because this is where people talk about problems.
There are many good bikes that go for a long time before you need to replace stators.
Heat is the enemy of them, they are oil cooled so cleen oil is also good.

As it's been said before (this is a common "newbie" topic), there really aren't that many stator issues given how many bikes were produced. This bike was produced for 20 years and electrics are almost always the most common failure on any bike or car (but replacing an alternator on a car is easy... it's not on a bike)- keep an eye on the charging system, replace the battery with a maintenance free one - relocate the regulator/ rectifier (not nescessary but reccomended) and you'll be fine.

I think the reason stator failure is such a hot topic here is because it's such a pain in the ass to replace it (so I've read). I will say that stator failures seemed to be statistically more prevalent on the suzuki GS series bikes (my previous ride) than they seem to be here - just going by the number of threads on each forum vs. bikes produced - completely non scientific.

Exactly as stated above, this is the sounding post of problems and fixes so don't over react to the amount of issues you read about here. With about 2000 members, most of which find this forum when there is a problem they're seeking help with, it would be easy to think these bikes are not dependable. They are, and keeping an eye on electrical on any bike is just something you have to do. Replacing a stator on this bike is a pain, but not having to do a valve lash job every 6000 or how ever many miles certainly makes up for it in my humble opinion! My previous two KZ's with inline 4's I had to do a valve shim job on. While it's not a hard job, it certainly isn't something I enjoyed! My buddy just did a valve adjustment on his ninja and his best friends ninja. Lots of plastic had to be removed to get to that on those bikes. But, it's normal maintenance and should be done periodically. On my KZ1000, it would have been pretty easy to do a stator job, but I never had to. They all have advantages on one hand and dissadvantages on the other hand.

As the others have said it is a small problem.

Some of it depends on when the bike was built too. I have seen many posts that indicate that the older the bike is the better the quality was when the bike was made.

For example I have a 88 with over 41K miles. At least 5000 were put on by me. I don't have a mainentance free battery and the Regulator/Rectifier is still in the factory position.

As far as I can tell the R/R and stator are still the factory parts.

In fact the only problem I have was voltage leak from years of corrosion. Fixed that with a can of tuner cleaner (see vulcan verses).

These are solid bikes. I would definetly reccomend getting it.

Stator replacement at 17,000 miles and again at 27,000 miles. Voltage regulator/rectifier was replaced each time also. Currently the bike has 30,000 and the third stator is holding up. I used Electrex products for both times.

I have not verified this but a catastrophic failure like an internal short in R/R could possibly fry the stator. Adding fuses to the stator leads will prevent that but will do nothing to prevent slow cooking of stator due to normal wear. My current stator is fused but I have yet to blow a single fuse.
