Any tips on what length kick stand to get? Noticed there are a few different options.

 

Anyone happen to have any experience with this 88cc big bore kit?

That particular kit you have shown is for the long-rod engines from '88-'15 Z, XR, and CRF50 models. Your '72 is a short-rod engine and requires a different piston configuration.

 

The kit you want for the '72 can be found here

Are these ok to bolt on and go or should I also upgrade the crankshaft and a larger carb?

 

They are bolt on and go, you'll probably want to add a bigger carb later on. Going with a stroker crank necessitates a race head, bigger carb, and an aftermarket exhaust for optimal performance.

 

Your going to need a HD oil pump and drill the oil hole.

Talked to the dmv today. Looks like I need to fill out some forms and bring the bike down in its street legal configuration. Also said I need to add blinkers. Any tips on wiring in blinkers or if there is a wiring harness I can buy that is already setup for blinkers?

 

I'm not saying this can't be done, but what you have in mind is very ambitious. Sourcing parts to do it will be challenging to say the least, and then whether California will give you a tag may still be in question.

This bike was never street legal in the USA. I think your best hope is to find a kit and adapt it to the bike. Your biggest issue is that most every such kit is going to be for a 12V CDI engine (which yours isn't), so you are going to have to upgrade the engine electrics (or find a new engine) to go with the rest of the stuff you need. Not going to be cheap. Break out your credit card and start shopping. These things will be what you need to start. These may not be exactly the parts you need (I think the speedo gear is for 10 inch wheels, not 8 inch), so look around till you get all you need. Best of luck.

One more thing. You may be able to source some of the parts more cheaply from a domestic source. Try Hooperimports.com They have some similar stuff and you may save a few bucks.

 

I think you are right. I will rig it up cheaply as possible and take it down to see if I can get it registered.

Battery powered gps speedo, or maybe a bracket to hold my cellphone to the handlebars. =)

Or CHP sells the headlight with speedo built in?
I should be able to find some 6v blinkers or maybe a tiny 12v lithium battery, led blinkers and a handlebar switch

 

Quinc, where are you in nor cal? I have an entire 6volt panda that is in a box that I would sell you... you could use whatever you want to get your bike set up for inspection pretty easily. Btw, if you didn't know.. pandas are z50 clones and everything is a direct bolt on.

 

PM sent!

 

Finally road the z50 around the block a few times! It is a blast! Deff going to make a great wheelie bike. Ran great too once i figured out where to put the choke lever, well until the throttle stuck open anyway. =)

 

Hit the bike with some simple green, brush, and garden hose. Fixed the throttle issue, and the wife took it out for a spin.

 

1972 Z50 Street Legal Build

Doing some research on CA laws and it looks like I might be able to get around having turn signals being my bike is older than 1973. *Note* If I end up making this a commuter I will add blinkers for my own personal safety.

i think getting it thru inspection WITH them will cause you alot less hassle..id say wire up for it..put em on for inspection and then remove them if you want

 

Well what I thought was going to be a budget build has turned into 600$ in parts coming in the mail... And still need to find some dot approved 4.00x8 tires.

 

Not to be a killjoy, but is a battery required? I had an overzealous inspector referring to VC Section 24252 with zest and zeal, asking where's the battery. Fortunately my Z50A was equipped... picky bugger.

Nice to see your desire to register the Z50 for the street.

 

I bought the 60$ wire harness from webike. Just have to figure out how to hook it up next! Also how to do the brake lights. My plan is to find the smallest battery I can and find somewhere to mount it. Do you have any pics of the battery you used and how you mounted it?

Also pulled the exhaust off and a chunk is missing. Not sure what it is called. Cam cover? If I upgrade to a 88cc kit would it include this part?

 

-Brake cables are sold with brake light switches integrated within.
-The K1 had a battery box already mounted... maybe you could install an RC type battery under the seat pan area. Your bike may need an AC generator and rectifier if you wish to charge the battery. Otherwise, just have the battery wired so it doesn't get charged, only to appease the law.
-The area near the exhaust port is how they were. Sounds like you're upgrading to a larger displacement bore and perhaps a new cylinder head with the 88cc kit.

 

Battery will just be for the blinkers, horn, etc to get past inspection. Good idea on using a tiny lipo battery.

And good to know about the brake cable! I have been through a ton of diagrams trying to figure that out. Is the front cable the same?

 

Yes, front and rear cables are configured with the switch within... have fun with the build.

 

Picked up some K75 4-8 tires. Only 45$ each shipped right now from: https://www.jcmotors.com/heidenau-k75-scooter-front-rear-tire-39724-p?keyword=k75

 

good info here on the electrical.

Been busy cleaning and polishing! Stripped the engine down and going to replace the piston and all the gaskets etc. Got started on the rims and tires and wow! The tires are stuck to the rims.. Also the the price just keeps going up, most likely going to need new rims, and going to need to replace the wheel bearings and seals, never ends!

Got my first order from webike!! Other order is back ordered till march.

Anyone have any tips on how to mount the speedometer piece to the wheel?

You might have a problem with that. The front hub has to be cut for the speedo drive. I think the early hardtail bikes had such hubs. I don't believe the softtails do. Here's a picture of a speedo drive on a Chinese Lifan hub.

 

Hardtail version definitely had that area notched out, and the hub was a bit raised as well like in the picture
