got up this morning have not started bike for over a week. now took off my grip lock on break lever. then went to roll bike back but would not move forward or back? started up sounded good but into gear it would just stop running. breaks are not staying on and no objects under wheels. gear leaver looks o.k and moves o.k got me puzzeld. last time i used the bike and parked it up it was fine.

Does it stay on with the clutch on?
Is it more of a stall or does it just stop, like stand down cut off?

no if i hold clutch in or out and put into gear it just cuts out, no stall. also wheels don't wont to roll foward or back with motor off.

does it have a stand down cut off switch?
also what gear does it say it's in?

What is a grip lock? Is that like a brake lever lock that keeps the front brakes on? Perhaps the brakes have siezed on if they have been held on for a week?

You had your grip lock on the brake .. have the brakes got stuck on?

Seized brakes won't make the engine cutout. My pick is the bike is in gear, which is why it won't roll, coupled with a faulty sidestand switch, which is why the engine cuts out.

yes stand cut off switch, i just tried with stand up and stays on in gear but shuts off when put stand back down. but still doesint wont to roll back or foward.

breaks are o.k as break lights only shine bright when i put break on.

bike shows neutral light is on when not in gear also only cut off when put into gear.

I would say that the bike is still in gear.

The clutch has locked up when it's been engaged and sitting for a long time. There's a real easy way of disengaging it but it's a bit rough. If you're not keen on roughness, look away now.

Get the bike in neutral and running. Pull the clutch lever in and release it a few times with the bike running and the engine oil good and hot (running a long time). Then, with the front AND rear brakes firmly (and I mean real firmly) on, knock the bike into gear with the clutch lever in (disengaged). The hot oil will help to free it but you may have to perform this a couple of times with quite a high rev level to free the clutch. It sounds particularly nasty when the bike crunchs into gear but it should free up after a couple of times and Bob' your uncle.

Let me get this straight...
You use a clamp of some sort to hold the front brake on when parked up? You remove this, start the bike, click it into gear, the engine cuts out and the bike won't freely roll?
Try these actions - in neutral, pivot the bike on it's sidestand to lift the wheel you use the brake clamp off the ground. Does the wheel spin freely? No? Then that brake is seized on and it might take a bit of brute force to break the seal of the pads against the disc. If the wheel does spin ok, then your rolling problem is because the bike is in gear.
With the engine going, raise the sidestand before putting into gear. Still cuts out? Then you have a faulty killswitch on the side stand OR seized clutch plates like Jimmy says.

try going up thorugh all the gears then back down while just standing still. you should hear it go though the gears.

correct. but bike will cut out when clicked into gear with clutch held in. but wont cutt off with stand up in gear.

Is there any movement forwards or backwards from the bike at all? If it's in gear it should rock slightly back and forward, if it's rock solid it'll probably be the brakes still locked on. The brake light switch is at the lever, so if the pistons in your calipers are seized on the brake light switch will still function as per usual. Prop the bike up on it's sidestand and give the front and rear wheels a spin, are both of them moving freely?

Right! That is a seized brake causing your rolling issue.

Still could have several causes tho.
1. Pads are simply stuck to the disc, This used to happen with some Brembo discs I had on my bike, if it was allowed to sit after being wet. A sharp shove broke the seal and all was well, except for the mark left on the disc by the pads making the brakes a bit jerky until it scrubbed off.
2. You have a problem with the pistons not retracting in the caliper. Get them serviced.

The bike should cut out if your sidestand is down and you put in into gear, it's a safety feature (I remember blasting around a left hander in the 90's on a 84 GSX750 with the stand down. Stayed upright but pretty much lost my lunch).

That's what I was thinking from the get go. The lever will probably feel different, the light switch will still operate the same, but the brakes will be locked on, no doubt caused by old brakes and the brake lever clamp (I have one of these, they are very good but probably not recommended for long periods).

heres my ansew for what ive learnt on here. too much freaken gunk around side stand switch i'll have to clean it. also front break siezed on as my daughter cant spin front wheel. i got holidays kids for one week me on my own next =]. how i unsieze the break tho?

Nasty
8th July 2010, 11:06
Bit of CRC cloth and a toothbrush for the gunk ... not to sure about the brake ... but I think last time it happened to me I checked the calipers and was able to do something with them and they had seized (I think that is what happened - was long ago)

For a quick fix you could give them a slight tap with a rubber mallet, but I'd recommend that you take them off and service them yourself if competent or take them to a brake specialist. Seals are probably on their way out and the pistons and bores may want a clean up as well.

If you can't even spin the front wheel, it'll be a shit of a job. You need to throw the grip lock in the rubbish first off. Then remove and disassemble the brake calipers, cleaning the pistons and reassembling with new seals. New pads makes sense at the same time.

With all due respect however, this is a job best left to a professional unless you're confident on the tools as brakes are the last thing you can afford to make a fuck up on.

GENTLY!!!! tap the caliper with a small hammer. GENTLY!!!
This should make the pistons retract.
Take your bike to the shop for a brake service.

Ditto. The OP doesn't sound very confident with things mechanical. Also, if the pads are well stuck, he'll never get them off the discs to start with.

cheers buddy your onto it with your bikes. your method worked even tho i did close my eyes. i reved bike and let clutch mostly out fast and after 3 times breaks unseized now and for the side stand i start the bike with it up not down and all is sweet. also big thanks to botney honda as john said to do the same thing. chhers all to use as well. will give as many reputation as i can.

You're welcome. Now take that bike in for a brake service. Now, you hear!!

Just as an aside, some bikes will not go through the gearbox when stationary, Kawasaki call it a positive neutral finder. It will get first, but not second.

Re the brakes binding, sometimes just pushing the bike will make them unlock. Found leaving a grip lock on the front brake for a period of time would cause it.

Who infered that a grip lock was a good idea? Get a disk lock if you want to stop the wheel turning....

It was more to see if the gearbox was still working than actually going through all the gears to see if there was a clutch problem, which there was and white trash told him how to fix it.

Nope. Siezed front brake, due to use of a grip clamp.
