Re: Tick tick clunk!
 

Another quick question- Is there anyway to loosen the tension enough to take the chain off without removing the back wheel?

Re: Tick tick clunk!
 

Just loosen the adjusters & the wheel will slide ahead enough for the chain to come off.(rear wheel needs to be off the ground.)
:) :cool:

Thanks Blaine!

So I have engine apart and it is quite obvious one of the valves broke of and it currently firmly embedded in the piston head. It also seems that the area surrounding the valves is pretty banged up. Is there a piece that can be replaced there or do I need and entirely new valve assembly. Also what looks like the piston sleeve looks to have a very minor scrape on the side. Does this always need to be replaced, if so is it possible to just replace the sleeve?

One last thing. Does anyone know where to find these parts other than eBay?

Does anyone know if GZ250 parts and GN250 parts are compatible with each other?

Re: Tick tick clunk!
 

Yep should be the same. :) :cool:

Thanks Blaine. I was able to find everything on a GN250 I needed for around 350 compared to the 750 just for the cylinder head of a gz250

Geeze man!

...That's gorgeous! hahaha. You should keep the grenaded piston just to look at.
It seems very strange to me that we have had so many of these pop up lately. I'm not really sure what's going on in the world of the GZ. Strange happening indeed.

You should be able to just smooth out the cylinder wall with one of those awesome ball-scrubby-polisher things. And you MIGHT be able to clean up the valve surface with lapping and a professional job, but I would honestly just look into getting a new head. I think this part is separate on Ronayers but I don't remember. I had looked it up for someone once before.

I hope it works out for you man

PARTS ARRIVE TODAY!!!!

To bad I'm in Texas, but as soon as I get home tomorrow it's time to rebuild me an engine and finally get back on the road. Any wishes, prayers or just general good thoughts would be greatly appreciated.
