Oh-Oh - shavings advice needed

PostAuthor: Pika1960 » Wed Dec 18, 2019 11:32 pm

Bike metal.jpg


87 Virago 1100, 57000km. My first bike in 40 years. This bike has been somebody's baby - looks pretty mint. I'm only the third owner. Bought it last winter, and rode happily all summer, until first oil change after 4000km.

Just a bit of metal dust on the magnet, but also a couple of particles. Crap.

The long Canadian winter is underway, and I can get into the engine, but I'm hoping there's some advice about where to look, or where to look first before splitting the engine. Or where especially to look inside the engine.

Or better yet, it's just a bit of crap the clutch throws out, and don't sweat it.

All advice gratefully listened to.

Just a bit of crap, don't sweat it.

99.999% sure it's the usual debris from the starter gears chewing itself up. (Yes this even happens on Gen2-starters)

I agree, just keep an eye on it when you change the oil, :yup:
If you want to see some metal sludge take the forks apart. I rebuilt mine five years ago and flushed them well and new seals. Just saw the right one leaking last week and after disassembly jeez smells bad and lots of silver. Guess that's what winter is for.

Thanks for the great news!

And yes, i have fork oil on the bench, waiting for attention. And the swingarm needs lubrication. And a new rear tire. And maybe even replacement for all hoses.

So i do get to mess around. But I'm glad not to be too much into the engine.

I am pretty sure this debris is from some gears between the starter motor and the primary. The gear with the original part number 5A8-15517-00 is discontinued because this issue and now it is sold as 3LP-W1551-00-00. I had to change mine because this gear wasn't engaging the primary anymore. When this happens, you can't start the bike: the starter motor runs continuously without a reason. Anyway, what causes this debris is the this gear grinding the primary in fail attempts to start the engine.
