The ZPower Project
Hi all,
The project is based around a GPZ1100 A2 frame.
The engine is a Z1000 A1 (1977)
The idea (Plan A) is to build a vague silhouette of a Z1 but mono shocked so I will be using Z1 paintwork etc...
The plan is to only modify the frame to accommodate the project requirements so everything else can be readily bought of the shelf and therefore more easily upgraded at a later date.
Not surprisingly none of the paintwork currently fits in any shape or form.
I slipped (well not quite but hey ho) the frame over the engine to see what initial mods needed doing...
The first immediately obvious obstacle was the rear suspension mounting bracket which is stopping the engine from dropping in. It also gets in the way of the ZX6R swinging arm.
It is to late to start on it today but I have some micro adjusters at the ready...
To be continued....

Really interested how this goes as I have a very similar project in the garage.
I have had ZERO luck in getting any tank to fit.
best effort so far was to completly screw up a Ltd tank by taking a lump hammer to the inside
Just cant find anything that will fit the wider frame tubes at the rear of the tank.
Next effort is to cut out the inner of a GPz tank and try to mate that to a tear drop outer.
I can only see tears comming from that. !!

Nice project. Ive a gpz750 uni trac that Im going to fit z1 panels too.
Fitting the tank is a peice of cake,if you have a welder?
Simply copy what has been done in the link.

i tried to fit a different tank to a frame that didnt want the tank to fit (Im not sure what bike it was now?),with a hammer to the base of the tank. Never again! Frames are lot easier to modify!
Good luck.

Every silver lining has a cloud...
The 750 Zephyr looks most like the Z1 tank, but your right...just don't come available unless they have a dent in...even thought about buying a bike and selling off all the other bits...but they still go for £1500..too rich for me!
I'm sure I can make this Plug'N'Play...just need to keep doing my research.

Cutting a couple of frame tubes is a lot easier than trying to weld the base of a diffferent tank in with the chance of fuel leaks. But good luck to you Gary! lol.
Just get the grinder out and cut the frame!!!!!!!!

Hi all,
Sorry it's been so long but my account was foo barred but Taffus has now sorted it for me.
Right lets have a look at getting the Z1 tank on the GPZ1100 A2 frame.
First do some measuring then a couple of micro incisions in to the old bent frame and remove side rails from the GPZ frame.
Vuala...
A couple of bits to trim off the GPZ frame and tidy.
Right ready for welding.

Ok done just a bit of tidying up to do
With the tank on...
And what it looks like fitted...
It all appears to have remained straight but I will be getting it jigged up and tested when I have finished by the guru known as Martin Russell. He did loads of our one off stuff for our Harris's back in the day including straigntening a few of our frames he he
He did the yoke conversion for me ZX6R on to GPZ1100 stem.
Next on the agenda is the rear suspension line up and welding

Liking this, keep us posted on your progress
Just a thought - have you tried the 'lock' now the front end is in, and the tank is on?
I know others have moved the tank locations back slightly (10mm or so but be aware of the tap fitment) to achieve more lock. Easier to do it now and alter 'lock stops' / tank mounts at this stage. Like I say only thinking out loud here ......a grown up will correct me here im sure.
