Winter Repair/Maintenance/Money Pitting

What's everyone doing with their old gals this winter?

Mine needed new cams, followers/rockers, the hardness worn off. Obviously valve adjustment, carb sync, new chain and sprockets (actually bought those in the summer).









Adding a little CF for looks





Should get her back up and galloping properly again! :)

Nice job. She'll be ready to go when the weather breaks.

Most certainly will be!
Having the shop check out oil pressure make sure those cams where actually getting good amounts of oil.
Other details too. I repaired the front fender i have a bit of repair to do on the lower but that can wait till spring. I have a donor fairing to cut up.
Very happy the way this old gal is shaping up.
Unfortunately in Canada it's a few more months of dreaming...

Wow, those cam lobes look nasty.
Looks like you'll have a few months to use all those snowmobiles.

I bought the bike last spring, A couple bike dealers in there but I'm the 8th owner, its a bit of rescue mission but love love how stock overall the bike was. Partly neglected but OEM. I can work with that, for this machine.
Its turning out amazing. It's a keeper I'll have lots of money into it, probably never ever sell it. Truthfully I want more of the same. J model restoration when the L is done.

I started out that way too. I had a 1992 J model and thought a K would complete the collection. That's where it all started....,

I still have yet to get a chance to look at my bike, but if it did wear through a valve adjustment in a year, I think I might be in the same boat for a new cam, rocker assembly valve train replacement.

This winter ( I work on my bike outside) I'll be doing valve adjustment, carb synch, and replace the front brake lever. Maybe brake pads, other than that, bike should be good to go.

I started with a leak down test and valve adjustment. Found what we we found... You never know until you turn over some rocks!

I worked for a dealership in the 90's. Kawasaki had an issue with cam lobe pitting on 1993 models mostly but it overlapped into 1994 models. The most I'd heard about were the ZX11's. Obviously the 7's were susceptible to it too.

That's good information... I'll actually probably keep my eyes peeled for another set of cams then.
My understanding is K/L/M all the same cams.
I'll be interested to know if any shit is caught in the pick ups. Might have run them a bit dry? But I've heard these bikes are hard on cams. Small price to pay for such pretty green track weapons. Just have to stock up on cams.

Well Spearzy, here are the pics of the cam wear on mine. They don't look as rough as far as the gouges, but the color has me worried.

They certainly don't look as bad as mine. Mine where pitting and scratching.
Like other members have said they look not too bad. Something to look at next interval for valve adjustment, something to keep an eye on.
If it's a j model it might not have the soft cam problem like on the L.

Spearzy, I hear ya.that's great to hear as well. I get a little paranoid from time to time when things shift with the bike.

If you get a chance, take some pics of the old cams and maybe put them up for future reference.
As far as winter work goes, I have a slew of things I could do to bring the bike up to pa, they're is just a lot of little things, you know? Replace oil of course, valve lash, carbs are emptied and clean, replace all radiator hoses, new oil pan, water pump gaskets.....things to keep me busy.

I just pulled the trigger on some Dunlop Q3's, I'm excited.
I'm going to attack the brakes next year, they are stock but in good shape this year. Love the idea of new lines, maybe different calipers up front.

Oh I have some ugly cam picks for all to see. I'm not the best photographer but this is worn out K/L/M camshafts.
Funny the bike ran fine, I discovered this as I payed for a full inspection and leak down test to see where I'm at with the bike.
Leak down was ok, which is why I'm fixing not replacing the motor. I'm assuming numbers are a result of ring wear but I may redo the leak down test after a good run when the motor is back together.
cyl 1 8%
cyl 2 5%
cyl 3 4%
cyl 4 10%

I'm also assuming rings as my exhaust has a hint of blue in it. Might be stuck rings the bike sat for a bit.

Oh check this out, a gentleman I found on facebook from Spain just hand made 2 very unique seat cowls for my L model. I suspect they will look perfect for a J model so I ordered the second as a gift for a friend.
check out those indentations! Looks more like a M tail to me. :)

Dropped $200 canadian on primer, paint, clear from colorrite. I also have an extra M number plate reproduction from RDDecals to match my current number plate design on my tail. I'm painting these both blue.

(pictured they are about 90% completed)





These are in the mail and look sick. I'll take pictures and do a seperate thread later and give you guys the contact.
Shipped for both I payed around 125 euros to Canada. Seems fair.

Wow. When cams go, they go. My cams had me worried becuase they had obviously shiny wear marks, but those marks became like a gun metal grey in the center of the wear.

Those have the look of imbedded metal. Man. Thanks Spearzy for the pics.

You were saying that k/L/M models cams are interchangable?
