Yeaaaayyy Z-1 Ebterprises!!


I have purchased a few items form Z-1 Enterprises, I am always impressed.

With some apprehension i purchased a new wiring harness, the price was ahh well not cheap. I however am a big fan of Snap on tools, Starrett tools, and anything of high quality.
High Quality is always worth the money.

This harness is really nice, so if you are thinking of buying one I thought I would post a picture of it. All the connectors are good quality, and there are even grommets where they should be. The instrument light bulbs are even installed in their sockets!!!

I also purchased a new tank form them a couple years ago, very nice as well. Handlebar switches, also very nice.

Picture is worth a thousand words..

TK, nice work. I'm a fan.. one thought, kZ's are'nt known as being hard on stators, but..they are an item which can fail without provication. simple age makes me think fresh would be insurance if going the distance. luck G

Do you know what the RAL number for the silver you had it powder coated is? It looks really nice!

Thanks !!

Pictures do not serve the powder coating justice.

I can make a phone call and see exactly what they used.

Basically it is one coat of silver, plus a coat of clear. From a distance it just looks like shiny bare metal, up close it is very glossy, just what Stoppee and I were looking for, brighten it up without too much bling.

The Stator, oh crap, Congress (my wife) will need to be petioned for another expenditure. Oh well just another contract cost overrunB)

I actually had a sudden failure of a stator once. Dropped the Eddie Lawson replica, and poof no chargie no chargie. That was a bad day. Fortunately it was the only damage.

I am running the new wirng harness through the frame today, if one of you would post some pictures of the stock routing it would sure help.

Thanks again for the compliments......

Stoppee, brang the elite scooter down here so I can put some .50 cal holes in it for decoration:lol:

Ted, thanks for the link to this forum. I can't resist a good bike forum. I'm on forums for GSX-R's, Blandits, thumpers and now KZ's. Your bike is coming along really nicely. I love the updates. I'll keep checking in here. The Mighty 160 (named the Hulk) goes to the dyno on Sat. I'm pretty excited and terrified to to see if it (1) makes any power and (2) survives. I sold a titanium pipe for my GSX-R so now I can put siding on the shop and start on the new paint booth. I can't wait for some good weather to get the KZ out and get it running for the year. Cheers.

Had a lotta help on this project, Stoppee, 341, the "Wizard". A fella that does the Baja 1000 on an XR suggested using a dirt bike rear brake to reduce weight.

Genious..those dam dirt bikers..

So we ordered a brand new CR450R rear brake caliper, and master cylinder.

The master cylinder has its own resevoir for fluid, so its a cleaner set-up, no tube and plastic bucket hanging out there.

The stuff looks like jewelry. I had the rotor machined to the diameter, and thickness of the stock CR rotor, and presto..about a third the wieght!!

Nice project.:lol: :lol:

I really liked that CR450 master cylinder, a really nice clean solution. That one will be stored in my hard drive for future use. :P

I really like your bike! You replied in a post I started for my project. I am installing a zrx rear end on my KZ1000 also.
I am wondering what chain and sprockets you are running.
What kinds of clearance or alignment issues did you encounter?

Hey thanks..

I sketched out (digital sketch), the fixture I built to center the rear wheel to the front.

After centering the wheel, I laid a long straightedge across the rear sprocket. Examining the clerance between the straightedge, and the flange of the countershaft, we came up with a 5/8" off set for the countershaft.

The rear sprocket, was ordered from sprocket specialties.

www.sprocketspecialists.com/

They are a smaller company, and have great customer service. I talked to the tech on the phone. Sprocket specialties made a ZRX sprocket with .050" removed from the wheel side of the sprocket. This is much easier than machining the carrier, and only cost ablout 20 bucks extra.

The spacing on the oppsite side from swingarm to the flange on the wheel to center the rear wheel was 1.330".

As I posted on another thread, the Japanese were using a very large tolerance, to center the neck on the steering head. It is very important that you align your bike, because they are all a little different.

Oh yea..

1 additional note well 2.

1. I am using a 180/55 Dulop sportmax tire it has a thinner profile for chain clearance.

2. Sprocket specialties encouraged me to use a 520 chain.

I should have listened. the 630 chain just clears the frame, but if it stsrts to smack around, it would have hit the frame, so i had to cut some clearance into the frame. Then put a plate over the cut section for strength. The 520 set-up would be much easier.

The "Scooter"..

Until 2008 facts about the scooter were mainly "Classified".

I can reveal a few Unclassified facts at this time. The scooter was developed under a Defense Contract on or about the year 2003.

The mission history is still protected; for the most part.

The scooter was a pit bike for Stoppee, and 341 racing in the WMRRA series in the Pacific Northwest. Unlike most pitbikes, it was not pimped out with long travel suspension, or an expensive paint job. Mission focused we like to say.

Developed at a super secure "Skunk Works" location, the top speed and horsepower figures are protected and cannot be published. The cardboard/fuzzycloth/fiberglass front fairing is inpervious to radar, IED blasts, birdstrikes, and some say even bulletproof, developed through months of wind tunnell and battlefield testing.

As it cruised around the pits weekend to weekend, a few smaller minded people made fun of it's appearance. However, oonce a year there is an annual pit bike race at WMRRA events. The scooter with 341 piloting won easily.

Perhaps 341 can release the details of that race. All I can say at this time is it was "banned" from ever participating in the annual scooter race again.

The scooter makes an interesting sound as it lands from jumping off berms at the track, something like a Couch being dropped from a two story window..you know..KKKLLLlluNNCchhhhhhcc!!

The pipe (exhaust) was designed using the most up to date 3d Cad software available tested and proven to scare weman and children with its "bark". In fact unbrella girls won't get near it even if it's turned off and parked.

The scooter actually crashed on turn 6 or 7 at Pacific Raceway, confusing the corner workers, as it ahh was not actually in a "Race".

People would gasp as we would simply jump off when it was time to stop for a burger, letting the scooter slide on its side to a full stop in the middle of the BBQ area. (See "Bulletproof section").

Currently in mothball storage somewhere in the Pacific Northwest, the "scooter" lies in wait for the next "Mission"


Stoppee or 341 feel free to add to or diispute these facts.
