My brother owned the same 1985 A1 model GPZ 600 in the late 1980's . I owned a blue and white one A2 Kawasaki GPZ 600 in 1990. I still have the pictures of me sitting on it. I miss the old GPZ 😔.
Just refinished my sons 600r. Lots of work ahead for ya mate! I had to repaint most everything, its currently in the shop for valve adjustment and carb tune! Good luck~
Thanks Michael. No kidding re lots ahead. I did my carbs on part 5, found out I'd be better with new bodies and rebuilt them again on part 7 (I think). Last week I found that my compression was through the floor (20psi), so spent this weekend pulling the engine out and removing the head. I actually did my valves spacing, but it made no difference. She'll be getting fully repainted. The frame is just a mess of brush paint and rust... Cheers for the comment.
Hey Glen get this, if you paint the bike gloss black throw on some 1995 GPX250 foot pegs cheap modernization and no unroadworthy foot peg rubbers again...
Some comments are "Kawasaki engines are made out of cheese" but that's mostly 70's technology with 80's high performance equipment the engines don't last, a GPZ600R has a °36 duration camshaft the GPX600 a °34 camshaft same the ZZR600 so if you get later model carburetors and a 4-2-1 exhaust the GPZ600R goes from 74bhp/80kw to 82bhp/96kw at the rear wheel, no you can't get rid of the anti-dive unless you fit ZZR600 front end and don't expect the air suspension to work simply get Progressive Suspension USA™ progressive springs and go to a 15w fork oil use a ruler to determine fork oil levels it's 282mm.
Hi, thanks for the comments. I'm going to disagree with the cheese bit. My old one got ridden and thrashed as hard as any of them ever were and she never missed a beat. I'm going to refurb this bike because of her and how solid it was despite the abuse.
Really interesting to hear the difference in cams, I've been trying to figure it out. I know about the power difference, but pistons are lighter, combustion chamber differences, con rods. Btw, I've ported and polished the head, just havent made the video yet..
I owned the same bike, same color for 16 years, sold it in 2008 looking better than new, I start following this videos today.
Thank you. I havent had mine since 1995. It's a labour of love.
looking at an 89 600r. will I have a hard time finding parts and will you recommend sources?

Get yourself another, or join the facebook group. Good friendly bunch. Itll maybe get your interest going again
Hi Glenn get this, score some GPX600F carburetors go from 145 to 155 jets plus a 4-2-1 exhaust get the front wheel off the ground at 3050rpm...
