KZ1000R.com Bike of the Month Oct 09.

Martin Stevens z1000r (83)

So I bought this bike off eBay in June 1997.

I used to have a Z1B when I was young which I always regretted selling

and my mate had a Z1000J which he painted green to try and look like a Lawson.

I also used to own a GPz1100B so big Kawasaki are in the blood.

I bought it unseen which I know is always a mistake but it looked ok in the flesh and I think the price

we agreed on was ok.

Problems started with it on the way home with the clutch slipping and obviously running lean as it got so hot.

With some tinkering I got it to run ok but then starter packed up.

I thought it was starter clutch issues.

 





 

By this time I had bought another total wreck of Z1000R which I intended to use for spares

so I transplanted the engine from this in to the other bike just to keep me on the road.

The rolling chassis from this I sold to Robw which is also on your forum.

More issues with leaking forks and generally poor build quality prompted me to take it off the road in

September 07

and commence a nut and bolt rebuild.

My objective was to streetfighter the bike but I wanted to retain the original period look and did have

thoughts of

Classic Racing or at least parading.

Most parts were sourced from eBay or the Z1OC in the UK who are really helpful bunch of people.

I also work for an American company so regular trips to the US have allowed me shopping at historically

favourable

exchange rates to raid Works Performance and APE for goodies.

I also used US eBay a couple of times and had parts shipped to a mate in San Francisco which

I collect and transport home when I go over.

Biggest investment has been in the engine.

 





 

I did not need to strip down the engine it came with as it literally fell apart.

The starter issue was because the rotor and starter clutch had literally fallen off the end of the crank.

The engine cases were cracked and most bolts were held in place with Loctite.

The only positive was that it was a GPz Unitrack engine so a great head and cams to go for real

performance.

I’ve used two engines to make one good one with all casings etc powder coated in satin black which

gives a lovely and durable finish.

Cylinder head was dispatched to Tim Blakemore racing to be gas flowed, 3 angle valve seats cut and

generally over hauled.

The rebuild has taken longer than expected as I get little free time with job and family pressures

but it all came back together

last month.

I fitted a new battery and much to my joy it started first time.

My neighbours were not too impressed with my Kerker’s race baffle at 10pm at night but I was!

I still had to sort the brakes and

a gear lever for the custom rearsets I have but with this done I took it out for a first ride a couple

of weeks ago.

What an awesome bike! Amazing torque and brick wrinkling noise! Smile was slightly dented with

an oil leak around the cam cover

but a happy guy so MOT booked and back on the road me thought……

 



 

Quick trip to local petrol station resulted in an issue on not running on all 4 cylinders (now found to be

a screw missing in the carb

on number 4 cylinder)

but bigger problem is a massive oil leak between head and block so engine is back in bits again.

I have a few ideas of what the issue is so hopefully not too much of an issue but we will be back on the

road next spring.
