If I remember correctly I believe they did not have wholes in the pistons. So my bad on that but they were wsm pistons. They did not look special at all really. Are their rotary jetski engines?

Ya well done. I understood "2 stroke" but I had a feeling as people started saying piston direction, I definitely recalled a time where I was unsure, as I was unsure about alot of things. Also just learning the function if the piston skirt too is huge. I never thought that deeply about it but...

So I will verify once I'm done with work but after careful review of my assembly I destinctively remember saying to myself that I installed the chambers on the wrong way, so I turned the chambers and briefly looked at the pistons but can't remember if I had the pistons orientated the right way...

I'm not familiar with boost wholes. Can you give me a description as to what that is? Also I appreciate sharing the knowledge outside of the pm.

I have, by the book, aside from the timing, assembled a brand new js550 piston port motor. Fresh hone (not bore) within spec with new ADR crank, all new seals, pistons and piston rings. Super odd the the exhaust manifold bolts only want about 5 pounds of torque but I did it. Anyway, as I get...

Haha yo that thing is sick. Have you actually ridden with that thing slapped on?

Noted. I was planning on running the 148 solas mag pump right off the bat. Iv heard that they do ride loose a little. I suppose if its too loose ill rectify with a larger pump.

Its currently built. Unfortunately shipping from tigercraft rn to the PRC is over 900 bucks and tony and i are in agreement that its way too overpriced and that it will come down. I told him to hold onto it as long as he needs too im trying to save as much money as i can as my first purchase is...

Anyone else have this out of the box from hydroturf?

dont plz.

I have yet to tune any carburetors but im setting myself up to tune a js550 with a high compression head. Im using this thread as my bible at this point. https://www.pwctoday.com/forum/pwctoday-riding-groups/midwest/midwest-pwc-riders/badgerland-jet-pilots/306829- Goes very in depth but not to...

Sick. Ill do that.

Yup.

Haha florida is a free state, i live the the PRC (PEOPLE REPUBLIC of Commiefornia)

Curious if anyone else has a reliable way of getting ahold of it here in socal. I imagine john wayne airport will tell me to piss off when i pull up in my truck with a bunch of 5ers ready to go.

Do you have any opinions on the adr crank.

I have a 440 cylinder on the shelf. Fairly certain i get that sleeved at 75mm and its now a 550. Any added benefits from that aside from it not being vast iron?

In depth

I pulled apart this engine to reseal it and this is what i found. Cylinders are scored to piss and crankshafts are wobbly everything else seems to be fine. Looks like shes due for a couple sleeves. I think stock bore is 75mm and i want to keep it that way as its a 550 and i just want to get it...
