82mm TLR porting. Pro-X pistons.
It just a case of chit happens.
1. Stuck a piston when I was running a TLR 48/44 carb set-up, Was at the beach riding one a section between the mainland and an island, water was like glass. Ran out of gas, no hiccup, burp nothing, just ran out of gas and lightly scarred a piston.
2. Blew a chunk out of a piston after installing JSS recommended jetting. Speedwerx pipe with OEM 38's.
3. Stuck a piston running Speedwerx pipe Dual 38's
4. Installed Stock Cylinders and pistons, loaned ski out to a friend, came back with a stuck piston. Single stock 44mm at that time.
Come to think about it, stuck a piston another time that season with the Speedwerx pipe.
Later determined that the Speedwerx Pipe did not like the porting with the combination of the OEM 38's and MSD enhancer. Guy I bought the pipe from told me that this may happen.

No builder can guarantee that you will get 3 seasons out of the SS motor. There are too many variables that they cannot control.
Air Fuel mixture can get out of sync.
Customer could run it at WOT for to long.
Customer could make changes to setup causing damage.
O-Rings could blow causing water intrusion or lean condition.
Gaskets could blow causing lean condition.
Crank can let go and destroy the whole motor, this happened to me in 2007. Only thing not damaged was the cases.
infinite number of things.
In 10 years I have gone full seasons with no engine problems to seasons where I have multiple issues.

Oil
Amsoil, Klotz, Maxima and Motul are the only oils I ever run.
Pro-X pistons only.
See previous post. Some of the "blow ups" were from just freak incidents. Others were from setups that did not work well together. Granted, I was not running an engine package from a builder. Call it Trial and Error. Your timing can be advanced just a tad to much and cause you to toast a piston.
I smoked a piston back in may running WOT, I said to my self "Better get out of this thing before I stick a piston", let off the gas and felt the RPM's come down way too quick. I knew then that "I smoked it".

That is why I like the idea of a total package from a builder. You pay a little more but experimenting can cost you more.
I do 5-10 minute WOT runs all the time in the heat of summer and nothing.

I race my SS motor all the time, WOT runs just on a race course wot 15-20 sec, etc.
That motor rips, it's fast as hell with that 14/19. I couldn't believe the top end from this motor set up.

A stock cylinder baby scream.
I know it's not a billet cylinder (has everything but the cylinder,..... for now) but it is a total setup assembled by Chucky over 2 years ago.
I can and have gone through an entire tank at WOT with maybe a 2 minute brake in between runs while the couchers caught up.
I run WallyWorld oil and 93 octane fuel as ordered by my engine builder and other than cleaning the outside, I do absolutely nothing.

Boris, I am gonna call BS.
Your saying you run with the throttle pulled all the way and never let go except for about 2 minutes. Your talking 40 minutes or so full speed.
When I rode my SXR at the lake, I usually kept it pinned. But this was going from one end of the lake to the other and back. Keep in mind, this is an Stock Class SXR not a SJ with a ported motor. When I did it, It was more for endurance training. If your riding in the surf 100% WOT then double BS!

Total packages are great. But not always feesible.
During the time with the speedwerx pipe. I was going from a somewhat setup package to trying something different.

I don't have video but I invite you down to the Lovers Key Ski Feast in July for some mangrove rides.
When I ride just with my friend we mess around with jumping trees, plowing through scrub and such so WOT runs are limited to maybe 2 minutes at a time.
When you lead a group of fast couches through one of the bigger trails, all you can do to not become impeller stuffing is to keep the throttle pinned. It's the only way to stay in front.
It is fun though to be able to keep a gaggle of 70MPH+ couches behind you. All their power means nothing when compared to local knowledge.

I agree with boris here. If you can't run WOT for a long time then your motor just isn't tuned right or is a flatwater freestyle specific ski that's tuned just to go blip blip blip backflip, blip blip blip barrel roll.
I am running XS porting on a 62T 701-.50 over. Dual 44's made out of two singles off 650 SJ's. 33cc domes with ~200 psi maybe a tad more. Running 93 octane and 40:1 penzoil or quicksilver. Pro-x pistons.
I can run wide open from the ramp all the way to the ocean with no issues right now. That is at least a 5 mile run and we do this every time we head out to the surf. I laugh when people say their ski will pass the 5 seconds WOT test. I need mine to pass the 5 minutes WOT test. If it will run 5 min WOT then it will run 40 minutes WOT.
Back to your regularly scheduled thread.

there were plenty of guys running very high compression and advanced timing on pump gas to get the grunt they wanted to rocket up a wave. The trade off was no sustained WOT.
I've had 220 psi with the stator advanced 3 degrees on my big bore motor with no deto problems. it's big power for poor people.
This is what I'm leaning toward more than anything now. I can't justify a 1000 and I really can't justify a 865 with 1 bore either. I'm pretty bummed man because I have actually lost a lot of sleep in the last few days trying to figure out how to get a 1000cc motor. It just ain't happening.
And 400 dollars worth of shipping/sleeves/re sleeving/clean up work...above and beyond a normal rebuild...does not sound good either.
I may do it but I don't know now. A poor mans big bore goes more in line with how much I actually get to ride/how much money I am willing to spend maybe.

yeah I did that on my Frankenstein motor. ported x case, ported 86 mil T cyl, power bomb, and a ported b-pipe. MSD enhancer, all else stock.
It was cheap and worked well. I don't run that kind of compression any more though just for piece of mind. I keep it under 200.

Considering the length of our season that's probably the best bang for your buck.

Right on bud,
Just want to help everyone make an informed decision, even if it isn't with our products.

SS846 with the upcoming half sizes would give you quite a few overbores.
