Motor
 

Just wanted to let all know that the motor that I purchased is in and running.....seller was great to deal with and the motor is everything that he said that it was. Parts alone are worth more than he is asking.... I would buy again from him in a heartbeat! He was very helpful to my techs in breakin info, etc. Absolutely no issues....

i will take the other 1 434 284 0485 andy lohr

Engine halfway through break-in period and is running like a champ!

Unfortunately at less than 25 hours the motor blew...don't know what gave up...tech pulling the engine to assess the damage. Likely will need new bottom end/block, will see. Engine was no problem until then. Wondering if even though the oil pan held 13 quarts if when running hard it was getting enough oil...usually showed 60 psi or so, except when throttled down quickly from a hard run when it would drop very low. When problem occurred I had just hit a big wave and gotten a little airborne, which Donzi's should and can do, but just wondering if should do something different in the oil system for the re-do... Thoughts?

I'm sure you spun a main bearing and the crank heated up and broke. Let us know what went on.

That sucks

Will for sure let all know what the heck the issue was...the way this engine was built it should not have happened...

i bought the second engine mine never made it through breakin, i will never buy anything from his azz again and neither should any1 else, 2 strait peices of shet

Damn thats crazy both motos blew what rpm were they reaching? I find it hard to belive 490 hp.

i never took the engine over 4200 , less than 3 hrs on engine
