- Vittorazi recommends the piston to be changed every 200 flying hours.
Although not a complicated operation, it requires a few tools and some mechanical skills. Nothing that you can't do at home with the engine installed on the frame though.
Here is how we do it in our workshops!

Very informative and helpful
Thank you very much!
He said he used Victor-Reinz Reinzosil Gasket sealer if anyone was curious
Can i use old O-ring under cylinder head, if i just want to check carbon buildup on piston and head? Or i only need new one?
Hi, Stephen whats up, I'm Pedro from Saquarema Brazil, I don't remember if you were here on my City in the World Paramotor championship 2022, I was working in organization of championship. I have a noise inside my engine, MY20, a noise like iron with iron , I did replace piston, roller bearing of piston but the noise continues, look like be inside cilinder the noise. Wuld you help me
Why is the small hole provide on exhaust side..? (On cylinder wall)
It’s decompression port, which is needed for easy engine start, as far as in know. And it should be cleaned if you have opportunity for do it
@@Vberegovoy thank you so much for replying message, but how it's worked...? I want see video

Putting a bigger piston into the cylinder without measuring it just based on the hours is absolutely unprofessional. The cylinder sizes vary by 0,01 mm between two selections. A one size bigger piston will be also bigger by 0.01 mm in diameter. The factory piston clearance is 0,05 mm, but the cylinder wears unevenly. Under the piston rings, made from chromed steel it gets a barrel shape and even elliptic, while the bottom part, that is in contact with the soft piston only will not wear at all. To put a bigger piston, the cylinder needs to be honed, to restore it's original shape and the "grooves" to hold the oil film on the cylinder wall.
200 hours!!!?? What kind of crap are you selling? And it's stupid expensiv also. If it's that terrible, how about including an extra piston and maybe a muffler, since that's gonna crack. Embarrassing. You should be ashamed with that price.
It’s an aircraft so you must make sure the maintenance is done and no issues when flying. They did have exhaust issues from bad design and also accelerated by bad operator warm up proceeders but they did offer replacements and fixed in MY20.
From my experience this motors build, parts acquisition, performance and reliability especially when flying makes it far better than most motors on the market. You get what you Pay for.
@@pepperjackshack2439 I have a PPL. I think I know what an aircraft is. And "you get what you pay for"... not much apparently when it comes to paramotors.
@@mrsonor1090 that’s great actually. Sounds like you’re sticking to planes 😂
@@pepperjackshack2439 Hehe, waiting for electric. The batteries are getting better and better.
@@pepperjackshack2439 yep, he knows nothing of our sport and the different engine providers and engine reliability on these. He said he’s waiting for electric. Well he missed the bus on that one too apparently. I’m on the 3rd batch of the sp140. Will be using it mainly for aero/acro and some thermaling.
Fucking ignoramus.
