battery

I have a 1977 kz1000 LTD. Ever since I bored the motor and put heavy duty valve springs in it, the bike is hard to crank over. I was wondering if anyone new of a battery with higher than normal cold cranking amps that would fit in my bike? Thanks

NOTE: Verify/confirm/Measure existing battery dimensions before buying any new one....

maybe you need to get a 9 watt honda CBF 900 or honda CBF 1100 starter......usually starts high compression engines

Or you can convert it to a 24V start system. You can get Lithium Iron batteries that will allow you to fit two into the space formally occupied by the stock battery.

My engine, 1982 GPz1100 with 1135cc high comp MTC pistons, porting, performance valve job with heavier springs had a real hard time turning over also. It would turn over really slow when cold but once it was warmed up it started normal, weird. My solution was to use the starter from a 1982 Honda CB900F, it is .8kw instead of the Kawasaki's .6kw. That helped a lot but it still cranked over slow at least for me when cold. I ended putting in a "Ballistic Fabrication" 8 cell Lithium Ion battery, which I believe is 210 amps. This helped even more. The bike still cranks slower than normal when cold but at least it doesn't sound like the battery is about to die. Even when the temps are low the engine will start without issue now. I have had this setup for about 2 years now and am very happy with it.

Will not turn the engine over....10.25 10 1 comp 1170 cc......took starter out and ran it with a battery....the starter spins strong but starts to squeal after a second.....also the shaft has a lot of play side to side. Bad starter I’m guessing What do you guys think?

Took the starter apart.....the bushing on the drive end is cracked

For a stronger starter motor, read this:

Using a Honda Mitsuba SM-220 Starter in the Kz (copied from the KZ rider website)

The CB F's used 2 different starters. Look for the one marked .8kw. They also have one that is .7kw. This owner noticed a difference when he installed his. He read that you can remove the outer housing, and rotate it. this will re-align the outer power terminal, to a better location. if you don’t do this, you will need to grind some metal from the chain cover to gain clearance. Also install a heavier gauge wire to the starter , I’d recommend 6 AWG(American Wire Gauge) welding cable with the correct terminal ends to match the treaded studs for the solenoid and starter motor. Don’t forget the cable from the battery to the solenoid.

The stock KZ starter is .6kw in size

Thanks MFolks, Just ordered the rebuild kit before I read your post....If that doesn't work out I'll give the Honda starter a shot.

Got a the Honda starter MFolks recommended (SM 220 12 volt 0.8 KW) on ebay...hell of a difference.....Turns over like the plugs are missing....I'm sure the new battery doesn't hurt, but its a hell of a difference.

Same thing here. Got a z1100 a3 shaftie with a wiseco 1170 kit.
My starter barely turns the motor over even with a full charge.

Spotted one of those Honda starters on eBay and its in the post.
I take it the outer cover is easy enough to realign so that it drops in - and the starter motor cover bolts line up?

I don't really get the 24v mod or the lithium alternative but that first post battery looks pretty good.
Great tip, thanks!!!
