Hello Bernie, everyone. I was working on an old '78 KZ1000 and ran
into some problems while modifying the engine. Just thought I'd drop
a line to say everything is going well and problems are solved.
First, for anyone wondering what the trouble was. I installed a big
pin crank in the old KZ. This is a street bike so it was important to
have the charging system working. Big pin cranks take a different
style stator & magnet. I just used what I had around in parts
engines. So a '81 Gpz1100 starter gear, magnet & stator & cover fit
right on without any modifying. It was suggested that the new style
regulator/regulator box be used instead of the '78's separate units.
I have to add that the 1978 KZ1000 is a one year only wired bike. The
service manuals do not correctly identify the wires on this model so
be aware. '79 is the first year of the late model stator. Anyway,
once you remove the side plate and look at how the three terminal
plugs are wired, it's very easy to understand how to connect the
three late model "yellow" stator wires. Coming from the reg/rect box,
the black wire is ground, brown is a switched positive, white is
battery & the three yellow's are stator. On the '78 you can use
either blue, white or green terminal plugs. There all wired into each
other from the back side so it's up to you which one to use. One is
going to get left off because your no longer needing to plug in a
separate rectifyer.
All that may read confusing but it's not a problem, anyone needing
more direction just email me at rw218@... or talk with Bernie
and he can put you in contact with me.
Curt Sexton moved to Woodlawn & Harry beside the Kentucky Fried
Chicken. He's almost my neighbor now.
I've also learned the limit of the Dyna S ignition. Speaking with
Curt, I explained the ignition couldn't time the engine correctly. It
was time to move up to a Dyna 2000 so this should fix the "unknown"
timing situation. Bernie you were correct when we last spoke, the
advancer weights are thrown out too early, engine wants to idle too
high. Don't want weights for an advance with big cams.
The 3 inch over swingarm allows for a 6 inch wide rim out back. Now I
just have to solve the problem of the tire sticking out past the
fender... Again, it's a street bike of sorts, have to maintain a tail
light & tag. That rim brings a problem as well, it's a ZX11 rim, that
means a 530 sprocket. I went with a Gpz1100 transmission, had to
order a special sprocket for a 530 chain. It's worth it though, the
1100 output shaft is huge.
Hey, I'll have this bike ridable this summer. It's running as far as
the engine goes. 250 horsepower sounds great.
