During lockdown I have managed to acquire 4 additional motorcycles . 2005 1450 Bobber , 2011 1580 Street Bob , 1992 Honda NSR 250 and finally a 1993 Kawasaki Z500.
The Z500 was stood for 10 years and had the usual clogged carbs and Petcock ( like all the bikes I bought minus the Street Bob ) . The tank I thought would take a little clean up but on my third attempt and third carburettor strip down I gave up and have purchased a new tank. In addition a petcock was purchased with a redress kit .
One thing that I am confused about it the Petcock has no prime so I am guessing carbs need to be filled with Gas then refit tank and the vacuum will do the rest ?
The old tank has been banished to the shed until I have free time to tackle the sludge and peeling sealant .
Its a fun bike to ride and looks good for its age .

Any info on the petcock workings will be appreciated

You are correct in your assumption that the carbs are vacuum operated. Cranking the engine over will fill the float bowls with fuel after a certain period of time. Or you can operate the vacuum on the petcock manually to fill the float bowls.

That NSR250 sounds like a fun project. They have to be a bit rare by now?

BTW....Welcome!

Hi
Thanks for the welcome.
The tank is dry as is the carbs so that is why I thought I would have to fill the carbs manually as the petcock has no prime . I will just give it a go with turning it over and hope for the best .

The NSR was a bonus as it was a bike used for a week off a friend 15 + years ago it then got stored and I came across it again in october 2019
