RZ250 cyl base gasket

Post by jools »

Like a twat, :oops: I only ordered one cylinder base gasket for my top end rebuild.
Has anyone in Australia got a spare? or a spare pair? -It's an '83 RZ - NOTE 250.

If the '86 is the same I can loan you a pair and you replace in a few weeks if that helps. Saves you waiting for the post. I'll need mine in about a month. PM me.

250 and 350 are the same gasket, as are early and late RZ, so sounds like you have a plan :)

Gavin and Jon, thanks very much for your help. I decided to get my act together and just simply make a couple of gaskets using the one I had as a template. All bolted together now.
Interesting Jon that the 350 and 250 base gaskets are the same part, - I know the head gaskets are different however, the 350 having larger bore holes for the larger bore.
Cheers lads.

Be good to get it running again, though I do need to check out a possible flooding problem.
The kid had trouble starting it for a while and I told him to try the prime position. It's possible he left it in that pos, because when I pulled the barrels off, the crankcases were full of fuel. But also there is a (very) slow drip from the fuel tap too which could have caused it (in conjunction with possibly suss float needles). It was sitting idle for a couple of months.

The bottom end of the RZ is really a 250, and Yamaha just went bigger on the cyls, everything 'downstairs' is the same. Only changes thru the years was to remove the tacho drive and different stators/flywheels, even the banshee uses the same main engine parts. It worked so yamaha left it alone from 83-2006(or whenever the banshee died).

Prime means the fuel runs free, on means it is controlled by carb vacuum. you can get a rebuild kit for the petcock, and also still buy a whole new one, but defo change those float needles.

Great that you are close to it making noise! :D

y'know, there's something to be said for a girl of negotiable moral standards.
Bikes of both sorts have their attractions. Like Hardleys, you just don't want to get caught riding the wrong ones.
