Re: Project bike in the post
Had a play today and got head off as you can see just marked piston hoping it's ok
Liners are fine
As head is fooked
So do I second hand head or new engine???

Re: Project bike in the post
I'd replace that piston mate just to save this problem becoming a holy piston and bottom end rebuild. Shouldn't be too costly though you'll need it re-boring and honing as that barrel and piston will have worn to each other.
New piston ~£30?
Re-bore around ~£25-40

New piston is £60.

I wouldn't be leaving a damaged piston in but its your call. Its impacted a valve and chipped the crown.
Id be looking for a low milage replacement engine or it would be getting broke for spares and buy a new bike.
Re: Project bike in the post
So that's £240 on pistons and £200-£280 on rings depending on rebore as let me see pointless doing one

Re: Project bike in the post
Why are the rings so expensive? Are they an odd size or fancy material?
Re: Project bike in the post
Thats why id be looking at a new engine or bike.
What did it cost to buy if you don't mind me asking?

Even ktm are cheaper for mine.
Mind you a piston is £320 compared to the £60 for honda.
