Rear wheel spinning in neutral

HamSambo

Had the bike on the center stand and it was in neutral with the engine ticking over. The rear wheel was spinning at around 2mph. It stopped easily when i put my boot against it and the tickover didn't change.
What in the name of god lads?


Edit: Sorry for making a balls of the thread title

This is normal, it happens in cars that are jacked up off the ground too. I think its the spinning of the input shaft from the engine transferring through the gearbox oil and causing the output shaft to turn slowly. It shouldn't happen if the bike is up to operating temperature though afaik!

They all do that, it's just a touch of hydrodynamic effect through the gearbox.

Handy for oiling the chain without the need to stick the bike in gear.

My SV chain doesnt move at all when on a paddock stand and in neutral.

Thanks for the replies.
Delighted to know its not something terminal

reckon its a good sign - little/low resistance in the final drive

Be very careful messing with the chain while in gear, it may end badly

Watched a lad the other day with a ZX-10 on a paddock stand and was proceeding to let the chain clean itself while he held the rag and WD-40 to the rear sprocket. I had to go outside.
He claims to know bikes, but I know stupid when I see it too

Yeah. If it didn't spin, I'd be worrying that the rear brake was dragging.

Sticky caliper???

goodlad

No idea man. Haven't a clue how to check something like that.
Sure I should be seeing a few of the lads tomorrow and will ask then to throw an eye on it

Get the bike up on a centre stand or paddock stand, slacken the chain off all the way and take it off the rear sprocket. The rear wheel should spin freely by hand with very little drag, if the brake isn't binding.

goodlad

Man, i have never even adjusted my own chain.. haha!
Its in for a service real soon so i will mention it then.

Holy cow. You need to check chain and tyres weekly not yearly. A bike isn't a car and isn't forgiving of mechanical ignorance, and mistakes can easily cost life, limb or skin grafts.

goodlad

Ah i check it weekly when im giving the chain a scrub and i check the tyres pressures nall. I do just nip into my local place and he tightens up the chain for me when needed. Sure i dont even own the tools i would need to adjust it :P

Its not that its ignore. Its just that i dont do it myself.

Not trying to be preachy but as already mentioned, they are far more involved than cars. If you don't have a decent socket and spanner set, I'd consider amending the santy list. It's not that you have to do it yourself but I can assure you if you had the tools to perform basic adjustments, you would. It's just good practice. Having total familiarity with your bike and it's consumables makes the riding experience very different too.

I did that
Luckily, and i stress that phrase, the chain was near its end of life so was a bit slack. Also it was a 125, so it was a light chain. Thank fully i listened to you guys on the forum and went small bike first, they're more forgiving in so so many ways.

Wow, did your fingers actually go through the rear sprocket??
:eek:

Lucky man. Must have been very loose to do no damage
