Chip in

I’m doing this site for the love of doing it.

However…. If you found anything in here especially helpful, please consider helping me out by chipping in for one of the following types of fluids that I use often on my KZ750 Twin…?  (These are all quick-pay type links to Paypal)

One quart of Shell Rotella T ($5.99);  The crankcase holds about 4000cc… which means I need about 4 quarts each oil change… which is around every 1500 miles… which is about once a year for each of my 2 twins. Help keep me lubed!

One gallon of gas ($1.99);  A gallon of gas will get me to work and back, so you’d be helping me get a day of motorcycling in, as well as keeping me employed…

One small can of SeaFoam ($8.99);  If you know anything about me, you know I’m a SeaFoam zealot.  It gets and keeps my carbs cleaned, and I’ll go through a few cans each season.  Can’t be without it!

And hey… Thanks!

    I need to locate a stator for my 1980 KZ750 LTD (G).

    Any suggestions? Thanks, Bob

    @ Bob

    Of course there’s always ebay, a junkyard, or join a forum and post in the wanted sections…

    If you have one in-hand already that is bad and you want a rebuilt one, make sure you check out my stator item here…

    I hope that helps…

    I’ve just bought a 1978 kz750b3 with less than 9000 miles. There is no apparent trouble with the starter clutch yet. I’m wondering if there is something that can be done pre-emptively that can prolong the life of the starter clutch, for example, removing the three allen bolts and retorquing to spec with blue (red?) loctite. As it’s a new bike to me, I expect I can cultivate the habit of trying kick starting before resorting to electric, thus also prolonging the life of the starter clutch. Any other ideas? How about, since it would be torn down for the retorquing above, pre-emptively replacing pins, springs, and rollers (i.e. the $25 kit I’ve found online)?

    thank you,

    @ james –

    Actually James, after my experiences with my starter clutches, if I were you, I’d do exactly that… Open it up, check the bolts to see if they are backing out, and if you are so inclined (as you mention), re-install with LocTite (probably blue).

    As for replacing the pins, springs, and rollers… It might not be a bad idea if you have $25 lying around that you need to spend, but I have heard in the past that some folks have had perfectly fine starter clutch parts, but the contact area on the starter sprocket (that grabs against the starter clutch) gets bumpy, causing odd behavior. You might just want to open it up and see.

    But then remember, once you open it, you’ll need a cover gasket (you can make one), rotor puller (bolt or rear axle), a rotor holder, etc., etc…

    I have been offered a 1979 KZ750 Twin with 250 original miles. What would this bike bring on e-bay-

    @Bob –

    Sounds like a museum piece!

    Seriously though, nobody can predict eBay prices. It has to do with how well you do the listing, the buyers at the moment, etc. The 750 twin is having a surging market as of late, but still it’s often less popular than other similar models like the XS650…

    But if yours has such low miles and is very clean, who knows?

    Good luck though!

    Hi, great site. Some good reading. I have just purchased a 76 z750 B1 here in the UK. I was thinking about upgrading the front brakes to double discs. Do you know what models I could look to for parts?

    @ James –

    There’s a post right here on another page with a few tips…

    I hope that gets you started…

    Hi All

    I was a member of the old forum and went by the name of “Bruster”. I have 2 ’77 750Bs and a ’78 parts bike. I Know a fair amount about these bikes. I had not been on for a very long time and I just now discovered that the old forum was no longer in existence.
    Anyway, I am back to working on the KZs and will hang out here for information and share my experience if I can be helpful…
