Stock pistons or aftermarket.

I've search many different forums and places and can't get a positive answers.

 

I'm thinking of going 4 mil. I was going to get domes cut for the stroke, but do I NEED to change my stock pistons?

No, if you run  110 rod. If you go with a 115mm rod, you need wiseco 795's

[bansheedemon]

If you dont want to break your motor then yes you need aftermarket pistons. I believe its like a wiseco 795 piston you need.

i wouldnt go 110 rod for the sake of pistons. if ya go long rod easier to resale or upgrade to a cub or serval later.

[Zillaguy]

The 110 rods put more side load on the cylinder walls causing the bores to egg shape, but they rev up faster and you can run stock pistons...... The 115 rod set up which you will need wiseco 795 series pistons for will last a lot longer without having to be rebuilt.. I'd go for longer life, rather than trying to save a few bucks.

So even if I get the cut domes, pistons will need to be changes off running the 115 rod.

 

Trying to wrap my head around this. Sooo many variables.

You need porting for 4mill also ya don't just cut the domes....

Yes I know, I'm just wondering about pistons. It's what will make or break me from upgrading right now.

New pistons are like 200 bucks. If thats gonna break your budget stay with the stock crank and get your motor ported. Pipes and porting cost some coin but the best bang for your buck, of course if you can afford it get the 4mil cause once you port your cylinders for the stock crank most of the time you can't upgrade later without buying new juggs.

^^^  ported stock stroke FTW.  IMO you'd be crazy to get a 4 mil crank without the 115mm rods.
