250-500cc My cylinder is a paper weight -- what years will fit?

As promised, I've had a hunt around but the only place that I can find one is pretty pricey! Maybe the one in Poland for 680usd is a better option, (it's certainly a cheaper option than out here). Sorry I couldn't help more

Have you seen this:

I just saw that Zip-Ty has two. And two 300's

I found one! It's in Perth but the seller might just post to the US. Might be worth asking!

I could probably suss this out if someone wants it? Easy enough to post overseas Cosmo.

Edit: Ahhh man it's in karratha! Bit too far to drive

Postage within Aus looks to be free!

One of us could just buy to for poor cosmo & just post it across!

Stand by, gents, my bike is still in the shop. The cylinder goes to the machining guru this coming week for evaluation. I appreciation all the attention and kind offers, BTW.

The bike shop got the bike back to me. The guy personally delivered it to my house. He did a bottom end on it. We started it in front of my house and rode it up the street. CLACK CLACK CLACK CLACK CLACK CLACK CLACK CLACK CLACK CLACK CLACK CLACK as soon as you get on it and get over 1/8 throttle. He says he had the machine shop guru guy check tolerances and everything checked out. I'm thinking millennium screwed up the "pump gas" porting. It must be ported for race gas or something like that and is detonating. I'm getting a bit tired of this - 6 months into this and a whole bunch of dollars that could have gone into a new bike. I think it's time to part it out.

Could be your timing.
If that's out too far advanced then it can cause pre ignition.
Your close keep going...

Halls have a 250 cylinder back up for sale! 200 bucks! Cheap fix & you are sorted!

Looks like the top end is included as well!

Bargain if you ask me!

Bloody hell that's cheap. Go for it

Yeah bargain for sure. Same or similar top end from 98/99?

Wow, thats cheap! Might have to snag one as a spare.

Just a heads up to anyone, these are listed for a 99-00 250 and looks like they have slightly different port timing from the 01-08 250's along with a different main PV. But it looks like the covers, secondary PV's, rods, bushings, gears, etc. are all the same.

Re built a 98 and a 01 your correct the centre top of is the only difference that I could see I didn't measure them tho. But side by side looked close.

Any idea if the PV's will interchange? They do look close in the parts diagram.

I wouldn't like to say, they looked close think the 98 was tapered and the 01 was more rectangular.
Think it would work but it wouldn't be right.
Heck at that price is worth it as a paper weight.
An you get piston.
