Michigan to West Sussex-73 Z1 for restoration

#1 PostAuthor: wilsonsjw11 » Sun Jan 03, 2010 5:01 pm

After restoring a Z1B last year I decided to look out for a 73 Z1 that would be my next restoration project one became available from Rick Brett and was purchased at the back end of 2008.I had been collecting NOS parts for a couple of years and this collection was given a major boost by the purchase of many NOS parts from Davy Doherty.This rebuild will be carried out with as many NOS parts as possible.
The bike with Z1B paintwork although it did arrive in candy brown and orange.

After stripping all the major components from the bike the engine was stripped,the only problems found were a wire burnt out on the stator and a siezed throttle slide in No1 carb.A couple of barrel/exhaust studs sheared on their attempted removal and this resulted in the head and barrels being sent to an engineering shop for professional removal.
The engine rebuild is being carried out by Mike Hunnisett this will include repainting,new liners and the head will be reworked by Serdi.The crank has been stripped,cleaned,fitted with new big end bearings welded and balanced by Chris Applebee before dispatching to Mike.
The clutch basket was treated to a new set of springs supplied and fitted by Ray Debben.
The new parts to go into the engine will include input and output shaft bearings,standard pistons and rings,new cam gear including cam shaft sprockets,valves and springs,clutch and springs.
The collection from Davy was'nt long coming into play when it was realised that the cam chain tensioner housing was from a later model but there it was all nice and NOS
As it was evident that the bike had been on its side sometime in its life all the hanging brackets were straightened and a little welding done to tidy the frame up.
The frame was then put into Motoliner to be checked for true for a fee of £70.00 a must I think before carrying out any restoration if you do not know the history of the bike,just ask for Ray a very knowledgable man
The frame was given a clean bill of health.
All parts for zinc plating,rechroming and polishing were sent to Mikey
Image
The frame was then sent for dry blasting with a very fine cleaning sand but still required rubbing down with 600/800 wet and dry paper before painting.The decision was made not to 2 pack or powder coat the frame instead Eastwoods extreme chasis primer and gloss was used with good results both coatings were "baked on" with the aid of a space heater in the garage.The only down downside of this warmth was that every fly that had decided to over winter in the place woke up thinking spring has sprung.

One little job that had to be done whilst waiting for the frame,stands and bracketry paint to cure was the restoration of the start solenoid,I had found a NOS item but it somehow got "lost in the post" when its packaging got damaged in the USA but I'll leave that one there.The first job to be done is to test the coil for continuity this should be around 3.7ohms if its healthy.Then with the aid of your kettle steam off the foil backed original label;
Image
Next job is to undue the terminal nuts and insulator fixing screws then desolder the two terminal wires, at the same time as desoldering the wires gentle pull the insulator away from the solenoid coil.Fix a little blanking plate onto the solenoid body,this is to protect it during the plating process.
Image
When you have done this you can examine the contact tips on the solenoid actuator and just clean them up with wire wool if carbonised.
Next thing to do is gather all the metal bits up and send them to Mikey for yellow zinc passivating and they should look something like this when they come back.
Image
Reassembly is a reverse of the dismantling procedure,I treated this one to new wiring and bullet connectors.You can now glue on the label you saved and then test it with your ohm meter before testing it across your 12v battery.
Image
And there you have it $200-250 saved.

Steve

Wow indeed steve, must admit that was the one that had
me a tad worried as to weather your blanking plate idea
would work and if indeed it would work again top job.

I did forget to mention in the script the blanking plate was sealed onto a small bead of silicon grease.
