Setting up carbs
Discussion
I’ve been (slowly) restoring my first bike, a 1985 Kawasaki GPZ600R.
I’ve got to the point of firing the old girl up, it idles ok after some adjustment and revs cleanly up to around 5k where it bogs down.
The carbs were cleaned out by a local shop and I’ve fitted a service kit so they have new seals, pilot screws and float needles.
The bike ran well when it was parked up last time, and runs well below 5k.
Any ideas of what to try next?
I’m getting frustrated because almost everything else is done, and I’m awaiting my nostalgia trip!

Post some pics up if you can, have a soft soft for any GPZ, particularity the 600.
Sounds such a minor thing but it makes a massive difference, when replacing carb parts always use genuine items, older carbs & pattern parts rarely work from my experience, we recently cured my friends carbs woes by throwing away the Tourmax items and replacing them with genuine Mikuni..

Diaphragms were fine, and it’s running well below 5k.
Intake and exhaust are standard, however the airbox is off as I was working on the carbs.
Someone on the GPZ forum has just suggested that this could be enough to make it run lean at higher revs.
No Airbox would be the answer I reckon, fix it up and report back.....Intake and exhaust are standard, however the airbox is off as I was working on the carbs.

I’ll get some decent pictures once it’s all together, this is the first time it’s all been one shade of red!
If I can get the carbs sorted out it’ll be ready to put back together.
May have to do some additional heat shielding to protect the bellypan from the nexus exhaust, it melted the old one.
