So, after 1 bad experience with Sirio based engines, you will never get them again?....
That you (your sponsor) bought the first Mega ZX engine really surprised me, but indeed it wasn't a reliable product, although I didn't really had to much troubles with it (expect for the flame-out problem).
The Picco P7-R, which was the same, also was of the same quality, Pico, had a bad period....
Yes, that ZX engine lasted only 1 race and then it had lost his compression.
Regarding my Xenon, if the crankshaft is softer and it hapens what was forecasted then it is not a quality issue but a choice of production to produce it cheap. If then a new conrod does not fit can imagine it is a fault in production. But if you read the bearings are also weak (what could be a fuel issue) then 1+1+1 is a lot.....
I've seen you break your 35+ within 12 liters (4 gallons) and you broke many more Nova based engines, way earlier then wanted....
Novarossi has a reliability problem at the moment, but I am sure they will solve this in time....
Yes, there is a quality issue at this moment, the bearings are weak but I believe it is only regarding the 25.8x14.5 bearing which are used in the Collari and the 359. Market protection by using/changing your own messurements seems a bad thing.
My 35+ lasted 12 liters, maybe to soon but if you take out maximum I think it is a reasonable life.
Yes, a R&B C5-Rody which did not last 3 liters for a worn out piston, 2 JP 2003 teamspec engines with maximum tuning and 7 liters of life and a R&B C5 not replacing the conrod after 7 liters... are examples of the last years where only one engine was my fault.
Like rmdhawaii said it is good that a company carries product to suite different budgets, like Ninja has 2 engine lines now, 1 affordable, and 1 ... less affordable.
Look at the "standard" Ninja engines. They are out-of-the-box not the most competive engines and the MRT version is expensive and needs an aluminium coolinghead extra to be safe in hotter weather so it seems.....
The JP 9 ports engine also has problems, like all 9 ports engines have, the liner with these 9 ports in it, is not that strong anymore.
You will propably never see a Picco or Ninja engine break there liner, because they are 7 ports.
Bullsh*t, only a few stories about the 35+ are known. It is almost the most used engine in the Dutch nationals and so far 1 or 2 known stories.
It is all about vibrations and how many flesh you let stay between the poorts. JP is known for breaking cylinders and thats only with his "team engines" which are maximum tuned. The Eagle has now 6 liters and still going strong and inside there is enough material on the cylinder.
Vibrations are not only caused inside the engine but also outside like a clutch, so breaking cylinders is not only the factory his fault.
