almost. I thinck Blade uses M8 bolts, KR1S has 10mm holes. So you either need to have bushes to fill the holes, or you make a 10mm thread in the calipers

I forgot : if you switch to KR1S forkes, you'll need 300mm discs

Pants, two discs needed so, KR1S DISCS or do others fit as well?

somewhere in the KR-kive, there is a list off all the KAwa's that use the same 300mm discs

UPDATE: STRIPPED THE FORKS AND SHOCK FROM THE FRAME.

The shock is rusted and blown and one of the forks is bent like a banana. Going to get a set of kr1s forks,on the lookout.

Cleaned the steering head bearings and regreased them, cleaned the shock linkage and will repack with grease.

Cleaned and primed the fairing stay, removed the speedo.

there should be a longer list.

ZZR600 isn't in there, and I thought some ZX9's used them to.

There is jan it's not an exhaustive list. GPZ500 s should be on there too.

Here's a photo of the shock I have.

It's perfectly fine, just the adjuster knob is missing where I dropped the bike one of the many times.

looks good. Looking foreword to fitting it.

Thanks for the offers lads, payments sent.

Here is the latest, I have my work cut out, so have roped in a friend of mine on the project!

Lots of heat and some gentle persuasion to remove the swingarm bolt

Ouch! Was about to suggest using some hydrochloric acid and cotton tips to clean the ally of the bore until I noticed the broken KIPS port.

Painful ehh, fun having the bike completely apart now though. Not looking for a show bike, this will be a pure track/race bike build.

Just a quick tip whilst you have it in this phase. Inspect the lower engine mount on the frame for any cracks.

It's a pisser when people get their bikes back together, then discover the fractures.
