Hmmm will be interesting to watch this one!

[timbo]

And then?

[Yella]

And then I am still going , hoping to get some time in the shed this weekend. Pressed the Stem in the ZX12 triple so going to do the fit up this weekend maybe looking at a zx10 front wheel so will see how that goes.The ZX10 swing arm pivot is 20mm and the L is 25mm the drawings below are the spaces for the pivot but not sure if I will use them. The 'L' fits differently in the frame than the 'P' model I did last time so it's all new again and thinking I will mod the frame tapping it out to use the ZX10 preload adjuster in the frame similar to the factory. Also getting ready to build the motor goodtimes.

My mate Peter made the spacer and machined/cut a thread in the ZXR frame so I can run late model swinger with all factory style mounts, very happy. The stem has been swapped over to a slightly modded ZX10 unit and the top clamp machined to fit the large stem. All coming together. Now looking for ZX6/10 wheels once I found a set at a reasonable price I will get spacers made to suit and the roller is done. then onto motor

Coming along but I am a little concerned about the wing arm to sub frame clearance, will know more once I have more time to play

[ozzy1100]

That frame mod would have been fun lol
Looks cool

[Yella]

Yep looked easy till we started , LOL got it done and it is perfect couldn't be happier with the end result

[ozzy1100]

Lol how many times dose that happen, it seemed easy before we started lol
Bwahaha never a truer word spoken

[Gix11]

Nice work Ian.

[FIGHTERMC]

coming along nicely

[Yella]

Picked up a ZX10 rear wheel will get some spacers in the next week or so then the rear is done. Need to find a 636 or zx10 front rim and it will be ready to the next step

[Bob]

Looking good mate

I know everyone know what a wheel looks like but "Pic or it didn't happen" is the rule. Wheel is all fitted. ZX10 wheel in ZX6 swinger in ZXR7 frame.
Next is to make the ZX10 front wheel work in the ZX12 forks (the 12 front fitted very nicely) or alternatively find one ZX10 fork leg and a set of triples. Wonder or different the 10 an 12 fork internals are?

[The Phantom]

Looking good.

I take it you have a set of ZX-10R forks and one is rooted? I know where there's a set of 2005 (radial brake) ZX-10R fork lowers.

[Yella]

Yep one of the ZX10 forks I have ha the brake mount broken off

[timbo]

I'm liking where this is going Yella

[Yella]

For some reason I cant add pictures but I have now swapped the ZX12 front end for a ZX14 everything lines up with the brake just need to make up some wheel spacers. So ZX14 forks ZX10 wheel and ZX12 master for the front happy days

[Gix11]

Should be sorted now mate. Sorry about that.

I ended up buying a set of ZX10 wheels so I have a spare rear now :) . I sold the ZX12 front wheel I had and after talking to the guy he was looking for a complete front so we to swap the ZX12 front for a ZX14 he had purchased so happy days. Everything lines up with the ZX10 wheel and ZX14 forks. Next I can focus on the engine :)

[LKC73]

Looks great Ian, With all these mods, you sure you want to dress this thing up fully? :cool:

[Yella]

It is a struggle mate

Thanks to Steve from RatedR I got me some pretty.


As side note is anyone else having issue with loading pictures from google chrome I have to switch out to I:E to get it to work

[Yella]

Front end all finished now, ZX14 forks and triples, ZX10 wheel and stem, ZXR bearing. Happy days

[LKC73]

Awesome mate!

[ozzy1100]

another cool build happening at the moment well done sir

[JimZXR]

Top job Yella!

What have you done with the ZXR front end?

[Yella]

Sitting on in the spares rack at the minute

[Yella]

78057806The next step, as you can see the 750 motor has 2 stiff rods, big ends are tight on crank but everything else seems good gbox is like new. The box in the 9 is boarder line but the rest is pretty good should all go together OK, My hope of 9 crack in 7 cases is out but other than that should be good.

[ozzy1100]

whats the drama on cranks mate? timing chains, different main dia or spacing,
cool project

[Yella]

Crank main journal diameter is 1mm bigger on the 9 everything else looks to be the same

[ozzy1100]

That sux arse, could be ground but not worth the effort

[Yella]

Yeah could line bore it but I will jut put the cases to one side for now
