I decided to take off both wheels at home and then to go to a tyre shop to fit new hoops.
I did so and while pushing hard to fit back tyre, the bike fell.
I had to quickly fit back wheel in order to lift it.
So the bike stayed lying for some 15 mins.
Then I wanted to test drive it and realised that something is really wrong with brake of rear wheel.
When I apply the brake, the lever is very stiff and actually the bike doesn't brake.
After some 1-2 secs of stiffness and lots of horror, the lever works somewhat.
I suspect air went into the brake fluid system what do you think please send any input that can help

i dont think air in the system would make the lever hard      are you sure its not a bent lever    also have you fitted the wheel spacer on the rear wheel correctly?

I checked spacer . it's placed as shown in service booklet.
Similar stiffness I faced when in the past I had misplaced bearing wheels of front wheel.

I'm not sure, but isn't there an issue somewhere with something (maybe the spacer) being shown fitted wrongly in the service book???
Anyone know what I'm referring to??
Parent - By aware Date 03-11-2012 18:46 Edited 03-11-2012 18:48
Shouldn't the wide base side face the drive belt side?

Booklet states "collar toward the inside"...
Parent - - By jeb Date 03-11-2012 20:37
are the rear brake pads in correctly
Parent - - By aware Date 04-11-2012 11:46
I spent 6 hours today with no luck.
I refitted wheel, put new pads, bleeded the brakes twice
It's ok until 5 kmh. Then it is stiff and it doesn't work.
When bike is slowing below 5 kmh it's working again
I HATE THIS BIKE NOW SOOOO MUCH
Parent - By jeb Date 04-11-2012 11:55
when the bike is below 5kph the variator freewheels so it maybe something to do with that or the automatic clutch.   so maybe worth a look at it.

Sorry I can't help, but that's
Got to be a clue..Ybe linked to the bike not being able to rev with the seat belt sensor broken, but if yu push it above 5kmh you can drive off. ?

I have problem when applying the brake of the rear wheel.
Please read history above.
To me it seems the wheel isn't fitted properly.

I made the following picture because
1) I see some increase of the diameter of the axle at the left end of it (yellow arrow)
2) I had lots of muck there (red arrow)

Are these normal ????
Parent - - By aware Date 04-11-2012 15:50 Edited 04-11-2012 20:06
Something is wrong
Really wrong
But what ???????????

BTW while rolling, the bike also makes a rattling sound that I can't understand where it comes from
I spinned both wheels at standstil and there seems NOT to be there any rattling sound

I think I know what you mean by stiff(maybe!) Could the abs be cutting in early.That would only be incorrect wheel spacing(the tophat spacer has flange inboard) or incorrect abs sensor air gap? Clutching at straws a bit here(as always!),but what are you trying to say in these pics?
Parent - By C1200 Date 05-11-2012 00:01
theres nothing wrong with that shaft!
Parent - - By C1200 Date 04-11-2012 23:44 Edited 05-11-2012 09:10
The stiffness is the resistance of the lever you get,when it feels like it isnt working properly when the abs cuts in maybe..you did not fit the front bearings correctly as per your other post, which altered the airgap,and I strongly suspect that inadvertantly you have incorrectly fitted the rear wheel somehow as well?.Also the black metal bracket should fit right up against the alloy hub carrier,cant see why yours has a step in it for some reason? Unless its the angle of the photograph.It looks like the bush has been pressed in somehow??
Parent - - By aware Date 05-11-2012 09:15
C1 200 you were spot on!
You focused my attention at the ABS sensor.
The gap was bigger.
Now why this happened who knows.
I had already a spacer there because my abs sensor was touching the grill.
The gap after reassembly was bigger now.
I could see it big enough but I couldn't locate my filler gauges.
You made me focus there. I put a thinner spacer and ok!
Now only I have a very soft lever going very deep most probably because I overbleeded the brake.
This forum ROCKS

Parent - - By purple hat Date 07-11-2012 13:14
Brilliant stuff Allan. :)
Parent - - By C1200 Date 07-11-2012 14:20 Edited 07-11-2012 18:13
Just a lucky guess Pam..Btw your poor old bike has suffered  from LPS syndrome already aka London parking syndrome  Im afraid to read just now on forum
Parent - - By purple hat Date 07-11-2012 16:40
Do you mean the Jade which was Imin's bike?  Apollo 13 bought it via myself as I was the one doing the selling of both bikes.  
Still got the VN800 all wrapped up cosy for winter. :)
Parent - By C1200 Date 07-11-2012 18:12
oh yes it must be that one then
Parent - - By C1200 Date 06-11-2012 09:33
By the way what happened in the end to the flooded engine al?
Parent - By aware Date 06-11-2012 13:50
flooded bike is 150 kms far from my main home.
I didn't touch it yet.
last time I remember it asthmatic.
when I play with it I will keep you posted
