Is this extra length going to be a problem?

Was a larger needle jet also included in the Dynojet kit?
Good Luck!

Perhaps an optical illusion :huh: or just my imagination :S , but the Dynojet needle appears physically thicker than the stock needle, whereby the Dynojet needle would result in leaner mid-range fuel mixture than the stock needle.
Was a larger needle jet also included in the Dynojet kit?
Good Luck!
There is a bit of a shadow on the pic. They are the same thickness at the top. Only the needles w/clips and shims and a couple of main jet sizes were in the kit.

Here's a drawing I did of the 550 A/C/D needles for comparison.

Measuring equal distances from the clip position, the respective girths between the two needles could be compared to determine which affords the thinner taper (for richer mixture).
May require a micrometer as opposed to caliper.
Good Luck!
Edit -- Sudco manual shows many different sizes and shapes of jet needles.

To be richer, the taper portion of the jet needle inside opening at top of needle jet must be thinner at any given throttle slide position.
Measuring equal distances from the clip position, the respective girths between the two needles could be compared to determine which affords the thinner taper (for richer mixture).
May require a micrometer as opposed to caliper.
I used a mic. But it's tricky on a tapered diameter. I didn't have an attachement for the mic. to measure with, I had to use the edge of the mic. jaws. Luckily I had a decent Starrett at work.

I struggle to understand the Dynojet kit for the 77-80 KZ1000. It's a "one size fits all" kit - yet you have a signifcant variation in setup on the 1000's - not only the standard and LTD models, but the shaft bike and Z1R - all supposely covered by the same kit. With one KZ1000 I bought, the PO installed a Dynoket kit and it would not run right with the jet kit - I seem to remember the slides had been drilled - I know I ended up swapping the carbs out for a different set to get the thing running well..
I kinda wondered about that application also as the kit I have says it covers 78-80.
I have an e-mail into Dynojet support for more info and am waiting to hear from them.

USA models with needle 16009-1032 5CN17
and jet 16017-1035 AO-4
Canadian models with needle 16009-1013 5CN15
and jet 16017-1011 O-1
Canadian needle appears to have 5 clip positions.
USA needle isn't very clear, but maybe only a single clip position.
Just guessing the Canadian needle might be thinner (richer) and/or jet larger (richer) because of USA's strict EPA regs at the time. But really haven't a clue as to comparison between the two needle sizes or between the two jet sizes.
Perhaps Canada model got a thinner needle and/or a larger jet affording a richer more responsive mid-range.
Wondering whether oem Canadian needle and/or jet might be currently available, as perhaps a better option than the Dynojet needle.
Good Luck!

But, mine's a KZ1000-B4 with a 5CN29 needle. Maybe that's where Dynojet (or me) messed up. Didn't specify the LTD model.
