Bike stops when put into gear? Won't roll foward or back?

[BoristheBiter]

o.k but i tried to accelerate forward in gear but no movement like break is on.

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

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.

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

yess just did that and gears change sweet as can hear them and feel it.

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.

o.k will try this later with eyes closed.

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]

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)

[onearmedbandit]

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.

[Nasty]

Brake service is essential .. your life relies on them working when you need them!!

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.
