stuck in first

[captaindonutbikes]

so she is running sweet but and its a very large but

clicked her into first (has been fine when clicking first and neutral) but the gear has got stuck in first.

before i tear her down to sort it out any suggestions ?

really gutted but trying to remain positive.

Probably one of the springs on the change mechanism hidden behind the clutch or if the pedal is floppy the pedal return spring

completely stuck in first no floppyness

I'd try rocking it back an forth with the engine switched off first and see if you can get it to come out.  Next step, take off the cover which goes over the clutch.  At least you can do this with the engine in the frame.  My 350 (same selector and clutch) got stuck in top once and I had to ride it home like that.  When I took the cover off I found that the selector bolt had become loose.  Put it back together and fine thereafter.

If I remember rightly, should you need to split the crankcases, it can be done leaving all the top end, i.e barrels, cylinder head, cam etc in place.

just realized my own stupidity

One down...four up?

Don't keep us in suspense...

Took the clutch case to find the exploded kick start parts loose in the case, thank fully no damage and i was able to get neutral and then all the gears.

and then i lost everything but neutral and second 

to get second i gave it a gentle tap on the selector shaft. but after that no more gears coming through

i believe this is right but could be wrong ( have been many times before!)

It can be hard to get all the gears to engage without the engine running, gears need to turn in order to align with the selector dogs.

Being a luddite, I blame electric starts.  If you had kicked it over to start it you would have been alerted to the problem earlier. 

Thank heavens it didn't go bang.

[captaindonutbikes]

so you think run it to get the gears in ? can't get first at the moment and i think it may we be a selector problem ?

[Bryanj]

spin the clutch shaft and the wheel at the sametime as moving selector drum to try and get gears, with all that fell off there may be selector/gear damage

I've had the bottom crankcase off the engine on one of my 550s in the past, without having to remove the top end. It does seem a shame to have to remove the engine for this but it may well be the only way to be able to sort out the gear selectors.
