New GPZ1100B1 project arrived today

#1 PostAuthor: JimBoUK » Wed Nov 27, 2019 1:42 pm

Hi all,

So my new project arrived today. A GPZ1100B1 US import:

Now to decide what to do with it ?
My first thoughts were go original but …
It's been converted to carbs. Everything to do with the electronic ignition has been removed and the injector holes filled with metal putty.
Although the exhaust is reasonably good for the age it is a B2 exhaust (it has the Kawasaki badges)
Being a US import I expect going original will give it less value than a UK bike so is maybe less justified ?

I might be influenced by reasonable feedback but my probable plan is to go original paintwork (red) with 4 into 1, braided hoses, maybe a fork brace, maybe deep braced swing arm, maybe different rear shocks and leave the carbs.

If I go for a 4 into 1 I guess the exhaust will have some value. Any idea how much ? (it will help pay for other bits).
Its got a dent at the top of the offside down pipe and a small dent just in front of the indentation on the left side for the side stand. Considering age it's very good with no rot, a few scratches and original baffles

I´d give her correct paint and seat.
Good B1 seat for sale I have.
Carb wouldn´t bother me.

If you want sell the exhaust i´d offer you EURO 550 + shipping cost. Would like to see those dents anyway.
Cheers, Uli

Ah, sadly the one on the downpipe is too big for me. Thanks.

Hi JimBoUK
great project you have there! Very sad about the dent in the N°4 downpipe...
The exhaust of a B1 wasn't black chromed, it was painted black and it had no badges. The brackets were bolted on like on the B2. The GPZ1100 Uni-Trac had the brackets welded on the silencers.
It's a shame that the holes for the injectors in the head are filled with metal putty...but are you sure it's putty? Normally that would melt due to the heat of the burning gasses in the compression chamber. But OK, so be it.
I hope you succeed with your project and don't forget to put some pictures of your progress.

Don't put it back to standard, it'll be awful, flexible and dull. Relive your youth and do the mods as you suggest like you would've done back in the day - trust me, it makes an average bike into a good one! :wink:

(If you hadn't guessed I'm not a rivet counter - I don't get it as nobody had a standard bike back in the day....)

I agree with Coose.

Mod it as you would have done back in the day.

Dents in the pipe can be taken out by filling with water and putting in the freezer....if you have a large enough freezer :D

Hi Jimbo,
I went to see the bike in the flesh and it's a great starting point. Whatever you choose to do it will be another Zed back on the road. Look forward to seeing how you progress with the project.

Gary.
