    Polaris SLX 780 ported/matched cylinders, heads, and new pistons with 3 rides

    Installing big bore, so don't need these. I just put new pistons (premium pistons with grafal coating) in it last summer and only rode it 3 times. The cylinders are lightly ported (pump gas) and matched to the cases. Most cases are exactly the same, so the matching should work for yours too. I will sell all 3, or individually if wanted. This boat was really fast with these cyinders, I just wanted to go faster with the big bore! $250 per cylinder/piston/head combo, or $600 shipped for all of them. Pistons alone are about $100 a piece, so this would be a good deal for somebody who wants to go fast, or needs to rebuild. Please send me a private message with any questions.

    I did the port work. Been doing it for years. I'm a certified Yamaha, Polaris, and Honda tech and have more experience with Polaris than anything. I run a small shop in central washington. I do port work on dirt bikes, snowmobiles, and watercraft. I'm installing a 795 big bore with a bunch of other stuff. I can even sell my carbs with the cylinders. They are all dialed in for these cylinders.

    OK, cool. I was simply going to say the 795cc kit is only .75mm over a STD 780. And you would prob get more HP from the ported cyls. But since you do your own porting, I assume you will do the same with the 72mm cyls for even more power.

    somebody has to need/want these pistons and cylinders. This is a great deal. Pistons and bore jobs would cost this much and you still wouldn't have ported cylinders. I can remove the heads and reduce the price a bit if that helps.
