*Moved to more appropriate section.

 

Walter? Water I take it?

 

Oh dear :( Is that the athena 144 kit too? They're are seriously expensive! Plus is that Nikasil plated :( That'll cost you.


I'm not sure how you run it without water it's just one of those simple things you forget I guess.


What are the plans for it. Probably be cheaper to get a standard barrel with the costs of replating it and pistons from Athena. I've read about those athena kits. All they are are a rebore of the original barrel. No porting differences at all.

 

I've got an article about it somewhere,

 

In fact I'd go as far to say that that barrel has absolutely had it. Also I'd get that bottom end rebuilt. Chances are metal would have gone into that bottom end destroying the bearings and seals.

 

As said they're Nikasil and cannot be rebored. They need to be replated. But it looks like a lot of material has been removed. Too much for just a simple replate.

 

You'll need to speak to a specialist about having that ally welded back up then replated. A company near me called Poeton will do that sort of work. They quoted me £130 for a 125 replate. Plus £30 if it needs any welding. That's if they can do it.


Good luck either way.

I don't think its his bike Calum, think he is showing us some of his customers bike parts that have ran dry of water, overheated and then died a horrible death, death by plonker as the clue is in the type of engine fitted. Liquid cooled uses liquid ie water and air cooled uses air, Simple.................................

Yeah i was saying that in the third person. Like i suppose it might have been easily overlooked that there was no water in the radiator. Cause as said I don't know what the crack was. Was it his bike. Was it one he just bought etc...
