View Full Version : Bodmin prep, rear wheel?
Just popped the sv on a paddock stand for the first time to give the chain a proper clean and lube and the rear wheel will only spin for around a quarter to a half turn with me spinning it by hand. Surely it should spin freely to a point?
Might be nothing. Any help appreciated

What happens after that?
Does the chain gather at the top, or the wheel lock or what?
It just comes to a stop. I cant hear anything grinding or rubbing, the wheel just feels tight. Maybe lubing the chain might help

Don't panic mines the same, hamfisted spindle tightening, It'll cause you no dramas, take a half turn off the spindle if your worried but I personally would not bother. It will never spin like a push bike wheel it's too heavy and the chain and front sprocket slow it down!
BTW is this you setting up ready for the inevitable I cant come in the morning?

What, you mean if you just try to spin it it stops or if you keep exerting pressure it refuses to move?
Because if it's the former then I think that's pretty normal, easiest way to tell is when you're moving it around in neutral.
Given the GM motto of "Check the simple stuff first" It's not in gear is it?
No when i spin the wheel with my hand and let go the rear wheel stops moving in about a quarter of a turn. I remember my ybr used to spin for something like 6 turns or something haha
@ thunderace What do you mean by spindle :oops:

The round piece of metal that goes through the the swing arm and holds the back wheel on (axle)!
But don't worry your 125 span more freely coz it's lighter wheel, chain, sprockets, brakes etc, It takes more force to spin coz its heavy.
I did try to undo the axle nut to adjust the freeplay but i dont have a socket/spanner big enough ...oopsie.
Now that ive just cleaned and powerhosed the chain it seems to spin about half a turn
More live Jammy mechanical action coming up!

Doesn't sound like a problem to me mate. When you spin that wheel you're spinning against bearings (which are probably old!), chain friction and mass, front sprocket friction, spindle tightness as has been mentioned and your rear brake pads which will be touching. Plus you probably have lilly livered upper body strength!
If you're really concerned you could adjust the chain tension all the way forward, whip the chain off the rear sprocket, remove the rear calliper and then spin it again to check for bearing/tightness only smoothness. But that's way overkill. Don't worry. IT'S FINE!! It's aint broke. DON'T FIX IT!

Dude don't worry. My rear wheel spins by hand until you let go then it stops! Been the same on every bike I've had apart from the baby ones, just lube it up and get packing!

Nice too see you pay attention!:smt040
hahaha Ive just lubed the chain totally and it spins about half a turn once i let go.
Interestingly, after i powerhosed the chain the wheel would spin atleast twice.... maybe its the water making the brake pads glide? But yeah. Im obsessive over things like this but i dont have the time nor willpower to investigate further, either way the bike rides fine.... ive only noticed now its on a paddock haha.
Cheers for last minute advice guys

Like a true prime minister, when quizzed on an issue, I don't formulate my own thoughts. I simply repeat what one of my other more qualified ministers have said. :p
don't power wash a chain, you're driving dirt and crap into the o rings. Should use a rag and wd40/meths and go over the chain repeatedly to clean it.

Or just keep on lubing it and watch the layers of crap build up! Works for me!;)
i'd go to the clinic if i were you then :lol: or choose a different hole :p

The harder you push it the more it will spin. Try pushing it harder, see it spin further and that will relieve your concerns. HTH. Yours truly.....

WD40 is a contentious issue btw Jammy. Many people say it gets behind the o-rings and eats away the grease in the chain. Others say they don't have any problems with it.
So the upshot is, if you're happy to fork out for chain cleaner spray, use that. If you're happy the WD40 people are probably right, use that.
And lastly, ignore everything The Idle Biker says.
Ive always just used chain lube from Hein Gericke. Now im trying this can of 'castrol race lube' for o rings. picked it because the can was red. :D

I'm sure there will be calls of "Erm don't think so" but its all a much of a muchness, the ones that say O-ring safe are just that, and the ones that don't weren't designed to destroy O-rings, its just the ones with O-ring safe are a little easier on the tiny rubber ba**ards, but don't worry too much chain lube is chain lube!
I clean my chain with Paraffin and a rag. Cheap as chips, damages nothing and cleans most things off of most things. Much sustainability

see post 15 too

WD40/Meths both more expensive than Paraffin so considerably less sustainable.
isn't paraffin more flammable?
isn't paraffin more flammable?
Than wd40-Yes
Than sprayed WD40 - No
Than Meths - No
However spontaneous chain combustion is not a common problem
i think this needs to be tested by a government science lab
I spy a vacancy.
Task 1. Cover Jamster's bike in various flammable substances and see which goes whoompf best.

Just trying to settle the concerns of a rather flighty noob, as long as its safe and it makes him feel better what does it matter, cheers btw for chiming in and trying to scare him into panicking about a back end that's fine!
