Try pushing the bike and see if they engine will turn over without the starter motor (6th gear is easiest - don't forget about the positive neutral finder).

It's not hard to remove the starter motor if you want to check:
- Remove sprocket cover (and gear lever) on left side of bike
- Remove starter motor cover (on top of gearbox)
- Remove 4 bolts securing starter motor and slide out.

Don't forget the starter motor uses the engine as a ground.

I wouldn't be suprised if the engine has cold siezed if it's been sitting around this long.

take the spark plugs out and put a few drops of oil in each cylinder. wait a while for the oil to soak in then try starting it.

pos neutral finder ....was at

and whats cold siezed
The positive nuetral finder is supposed to stop the shifter from travelling too far and overshooting nuetral when trying to shift out of gear when the bikes not moving.

Cold seized means that the engine parts have stuck together due to remaining stationary for so long.

Have you established whether the engine has seized by trying to push it in gear? If the engine has not seized has the battery enough charge to turn the starter over? If it is neither of these it could be the starter clutch, My bike was sitting a lond time and although it started at first after a while it made a noise but didn't quite kick the engine over, this was the starter clutch. The parts are not expensive ( about £30 ) but you really need to remove thengine and turn it upside down to replace.

Have you tried bump starting it? if that worls and there's plenty of life in your battery it is probably the starter clutch - it's a fault endemic to the 55o's

Did You Check The Coils For Any Cracks.sounds Like A Stupid Question, But I Had A Customer Come In With What Sounds Kinda Like The Same Problem,we Checked The Coils,sure Enough There Was A Very Small Crack In One,just A Shot.THE OTHER TUBE YOUR TALKING ABOUT IS FOR THE EMISSION CONTROL SYSTEM.CONECT FROM ONE TO THE OTHER TO ELIMINATE,WHEN YOU GO TO POD FILTERS,YOUR GOING TO NOTICE WHEN YOU GET IN STRONG CROSSWINDS YOU WILL HAVE TO START TO FEATHER THE THROTTLE BECAUSE YOU WILL BE RUNNING LEAN ON 1 CYLINDER.I ONLY PUT THE PODS ON FOR SHOWS,WHEN I RIDE I PUT THE AIR BOX BACK ON WITH A SINGLE K&N IN THE BOX.THE ORIGINAL BOX WITH A 4 INTO 1 EXHAUST,AND JETS YOU WILL GET THE MOST PERFORMANCE OUT OF IT WITHOUT DOING A BUNCH OF MODS TO IT,JUST MY TWO CENTS,I HAVE 9 KZS OLDEST A 76 KZ440 MAD MAX CLONE,NEWEST 80KZ750.

Mr Stabbed bikes shooting!

Hi,there, well it seems like we both have the same bike, in the same state and in the same country - so where in scotland are you.I live in glasgow but am not originally from there.

The problem with your bike just may be as simple as having the ht leads on the wrong way - have you checked, because mine were actually marked wrong.
I have swithed to individual filters, because they were cheap and the flexible rubbers on it were expensive to repace. The guy had it before me cut through them to get the airbox out, then removed tank and seat, at that point he appears to have left it, for 5 years!!
have you found anywhere that does second hand spares, I may need forks.
Also have you found out what jet size you need to go to and the circlip setting. Any info we can share can only help as i want mine to get it's first mot this nillenium before spring.

I'm near glasgow, and am having trouble getting it together. When I tried to remove the engine to fit the new starter clutch it was transpired the engine fixing bolts where corroded in place as it had been taken for a ride along the beach before being put in storage for 6 years. I had to use a grinder to get it out then pay to have the remainder of the bolts machined out. I am till waiting for some spares - the back brake assembly. I did strip the bike back to the frame a repaint it, I then repainted the tank and side panels a metallic blue. I set up my own warm room in the garage ad although it's the first time I have used spray paint it lokks good. I have an email address for a chap in Leeds who is breaking two 550 ltd's so if you need any spares let me know and I'll give you his email address. I;ll post some pictures when I get it all together.

I know it's not funny about your tank, but it is! :mrgreen:

Thanks for the laugh, hope the two of you can meet up and exchange parts to get your bike running.
