One Compersion Then Clink :(

Just a note to go with sudoxe's second pic, if you hold a ratchet like that you never be able to tighten or loosen anything.

Tone of the post with the bold text and all, I agree with what you're saying though.

He's taken the plugs out which means there's no compression there to push against, it should roll forwards in any gear with the plugs out.

Didn't realise that, cheers for putting some useful information my way!

I was only getting at the way you were saying things, not what ya gotta say, it just got my back up a bit as I don't like being talked down to.

If it's mechanical then it's probably something really basic like the starter clutch mech locking. I once had a GPZ500 in for repair that locked up like this, and it was a broken magnet on the alternator locking the engine solid. It'd turn one way but if you turned it the correct way it locked up.

Good luck with it fella, and don't let it spoil your Christmas.

Sorry - end of a long day with the usual Christmas eve rush probs. I didn't conciously mean to talk down to anyone.. It's a problem when you've been raising a shed load of kids though I'll make a new year resolution about it.


I have been where Big_G is and I would have a worm in my brain about it.. Lozzo is right though; forget about it until you get time to have a proper look - or leave it to a garage? Hopefully it is a simple repair.

Cool ejohnh, lets put this down to Christmas then!

Have a good one.

Keeping my fingers crossed that its a cheap and easy fix for ya G.

have had a look to day as have been at work no work on but have to be there

any way. It was good as had 3 people helping me and all work shop tools at disposal along with cnc work shop .

Some one on here got it right

was all down to the starter motor engagment mech. So am off at crack of dawn tomorrow to get new starter motor. Boys at work seem to think it wont be hard to cnc a new starter motor clutch ( blanced etc )

please see engine manual section 3-84

Will be up at the crack of dawn and devote my day togetting it back togeather.
