Easy to melt any 2 stroke piston. I would like to hear your theory on the 95mm piston being easier?
TPE-964 Engine?

Well, volume increases faster than area. For a given rpm, smaller bores can dissipate higher combustion temps. Big bores are fine for freestyle use. I do wonder how difficult it would be to keep one running in a couch. Sooner or later these cylinders will find their way into long hulls that get more WOT use than intended.

Very true, we don't always get what some may consider the "whole" story or all "available" info, be it good or bad. We have seen it recently with a few other products where owners were hesitant to, or just didn't, pass on their actual experience with some products. I tend to believe with the relatively short time these have been available these motors are no exception to that. Most seem very happy, so OP you can choose to pull the trigger with the given "available" info you have or pass and move onto another builder whose motors have been around longer and issues have been disclosed and for the most part rectified. Take the info you've gathered here, talk to TPE and decide if you are comfortable with a purchase of a TPE engine. Its really that simple to me. Doubtful you'll get all the info you would like to have. Good luck and have fun.

I wish I had something witty to say right now but why start any more of a pi$$ing match. Truth be told, any engine from any builder can fail. Other than a cast cylinder with Nikasil (which is already a proven design) this engine shares the same components as its competitors.
So now that we know Nikasil is more durable than a steel sleeve, please oh please tell me what about TPE would make it more prone to failure than any other engine on the market? And let's pretend this is a college course, I want a real logical answer. Not something a guy you know who built 2 strokes in the 80 s told you.

Power valve hitting on piston...

pistons and cylinders expanding at different rates. resulting in good compression cold and bad compression hot

Or uneven wear do to hot spots and growing in select spots expanding and contracting.

there are a lot of reasons that cast is difficult to work with in a race engine. im not saying it can't be fixed. but there is a reason high end racing engines in every sport of racing go to billet blocks. cast is inferior no matter what you do to it. once again not saying it can't be a good motor. it will just be hard to push the same power and heat and extreme levels from a cast part due to casting imperfections showing there nasty side long before a billet cylinder will.
once again please don't take this as ragging on TPE. you asked for an informed answer.

Funny, just about EVERY high end racing motor IN THE SPORT OF PWC RACING uses a cast cylinder. In fact, the ONLY win of any pro class racing motor I have heard of was Botti way back in 2003 or 4 using a Dasa pased pv kawi.
There is so much bu11poop thrown around on this site you would think there was a rodeo coming up.
As for the OP, there are very respected people in this sport who are currently using the TPE set ups and have been very vocal of there happiness with the product. There were a bunch of people at the freerides over the last couple of weeks who also got to try them out, as seen on this very thread. Unfortunetly, there are also a bunch of dumba$$es, just about all of whom DO NOT OWN A TPE MOTOR who like to throw stones on every thread about Erik and his work. I call this 'little dick syndrome.' You can figure out who is who on your own.

well i have a very small penis but that has nothing to do with it..... lol. i was asked what the possible disadvantages were. not what the actual problems are or if they are user involve or not. jsut what a possible isadvantage from an engineering specification was. i plan on buying a TPE motor. if for nothing else because it is a cost effective option with a good base of people saying they are good. but its okay keep adding to the negativity of this site with your name calling.

I have a tpe on the way and I will give you guys a honest review on my personal experiences after OWNING the tpe for a while. No b/s... How it should be.

J0hnny,
My post didn't point out a single username and wasn't pointed at you, but if you took offense to it, maybe we all know why now. I don't tip toe around anything, ask anyone that knows me. Unlike some on here, I don't try to be coy with little innuendo and crap like that. I tend to try to not act like a 13 year old girl. Again, not pointing directly at you J0hnny, generally speaking.

no i just find it funny to joke about small penis's because it throws people off..... see 13 year ol girl i cant even make comments about that. that just aint right 
lol. i honestly want to try one of these engines. but i am still convinced much of this sport (not talking about pros) is jacke up. "this engine hits like a monster!!!" okay cute. what pump and prop setup. a 144 with a 9-14 vs a 155 with a 12-19 on the same engine are going to hit totally different. talking about "HIT" from an engineering standpoint means nothing and i laugh every time i read it because it means nothing. my jeep has "HIT" better than most 9 second drag cars. gearing is an amazing thig lol. but it isnt sustainable controlable or the best for every situation.... but rant over back on topic. anyone run the 1100 tpe yet? thats what im really interested in.

You are correct, there are a lot of people in this site who wouldn't know true pro level power if it fell out of the sky. But like I said earlier, there are some people on this site who are very well respected who have and are using the TPE. None of them have had anything bad to say, in fact, it's been the opposite. But, most of those are smarter than the average bear, either are good enough on there own to get the entire package right or good enough to follow direction.
NO MOTOR IS PERFECT and beyond failure. Team Kawi used to have a million dollar budget per year to run the tour back in the day, even they had failures.

This site expects a plug and play engine and there's no such thing. You can't drop it in and expect the carbs and pipe to be perfect, or not to have to adjust the pump/prop setup. And I would venture to guess that the vast majority of people on this site have NO IDEA what curve they are running, and even fewer have ever put a light on it to see if it's truly accurate. How many even know their port timings? But they're just jet skis right? You can't hurt them. They are meant to be ridden hard and put away wet.
Fact is that no one engine is going to fit every single riding style perfectly. I run my skis at sustained RPM's chasing boats, so what does that mean? It means I run my squish a little looser, and that I pull more timing up top, and I'm not running 200lbs of compression on pump gas. So when some guy at a free ride hops on my ski it may not have earth shattering power, or be the latest and greatest in flat water, but it'll chase down a 60' Sea Ray doing 35 knots and never miss a beat.
Scottie is a racer and probably looking for that extra 50rpms, does a free rider need that? No. Fact is most people probably have 10x more motor than their level of riding supports. I'll equate it to the checkbook boater, in the 250k Intrepid, that can't put it in the slip.
I'll shut up now.
