Cam chain tensioners should be replaced along with inner cam bearings and lifters. And of course gaskets.

This is the lowest cost way, not the best way.

Quote I got from local dealer was for replacing both pistons and ring kit. No new cylinders.

complete gasket kit

That is a better way to go.
Looks like the gasket kit is $170.99

@pyuchem If you were seriously just fine with what you had? This makes the most sense in my little mind.

I made similar decision a few years ago concerning an EVO it had 48k on it.
It had some broken rings on the front cyl.. Purchased some take offs, had a machine shop do they're thing and never looked back.

It is worth a consideration. Do your best to find a good Indy or shop to to consult with some face time

I had to revisit my order estimate after I put that here. I was under the impression kit included cylinders, Looks like no cylinders only pistons and ring kit. Not sure if I need new cylinders, I'm guessing once they open and look inside, they will let me know. Plus I'm bummed about this and not paying attention, looking at Fuel moto kit and other options. So my mind is all over the place. I was really hoping this bike would go past 100k+ without hiccups. But that's not the case. Have been also thinking of Can AM or something else. But then I feel I should fix this and give another shot.

Mabey the pistons are oversized and the original cylinders can be bored. Which isn't a bad thing.

Hone is very important. Do not put new pistons in old cylinders without honing.
I hope the quote you got for labour would include this.

Thanks just called Lonewolf HD and service tech told me that they will hone and do necessary work on the cylinders for new pistons. I asked him to also add replacing 2 tensioners, lifters and oil pump.

Don’t forget inner cam bearings. Not the caged ones either. I think the dealer calls them the Screamin Eagle.

I would do lifters and tensioners, I would also do cam bearings when in there.

I would not do cam plate or oil pump unless needed. I just reused mine at 70k. Maybe oil pump if you never want to look in there again. I reused my pump and cam plate.

Normally I prefer stock pushrods, but the cam I used reqiuired adjsutable pushrods. So in the future it would not be hard to do oil pump and cam plate. In my 2001, I just out oil pump at 90k for the heck of it, and kept cam plate.

I would also consider valve guides and springs for the heads, myself I would rather spend money there, than a cam plate. Unless some damage.

I did not look at estimate.
