Wow, I'm putting that motor in my next atc 70 build. Already have the motor. If you don't mind me asking, What was your timing set at, & What was your RPM's Allowed to reach. Also was there a oil cooler on the motor. Sorry for all the Question's But this info might help me on my set up. Thanks.
How many hours on the motor and how do you ride. I found these motors need more rebuilds then a normal motor. The flat pistons have a tendency to rock in the cylinder if the clearances get to large. And then pow shattered piston and a broken connecting rod. Just curious not trying to tell you how to ride or what to do differently. I am just trying to gauge the rebuild time for the 190 motor.

This was not a stock motor. Arden, isn't this the motor that you put the high compression piston in, then you couldn't kick it over? Isn't this the same engine you blew up a few months ago after insisting that you didn't need an air filter. Your the only guy I've ever seen run a dirt bike and swear it doesn't need an air filter. Or was that a different one. I'm not sure, You definitely have a special talent for destroying engines. I remember last year at the indoors race your bIke was running so rich we thought you had a gas leak. Hell it was blowing fire out the pipe. Another Titanium Engineering build. My guess is that after you did your little piston mod, it blew all to hell, broke your crank and blew your cases apart. Oh, you have to start running an oil cooler too. You can't run an anima without an air filter, and without an oil cooler people. That's pit bike 101. And do try to use the actual Daytona 190 parts to do your rebuilds. It makes the difference.

Have been running my daytona 190fdx for about 35hours still runs strong. changed piston at 20h, looked fine but its so cheap so why not be on the safe side?! I have stock timing and rev limiter on lowest rpm duno if that matter but it works fine. Never had any engine last this long!

wrist pin was perfect... Clyinder was perfect.. (Except where the rod caught it at the bottom & broke a piece off).

this motor had about 30 hrs on it. (New piston, rings & pin about 4 hrs ago). I rode it as hard as it would go on big tracks. (Never pit bike tracks).
I'm not negative about it breaking. These are GOOD motors. I'm going to keep running one. Everybody builds them a little different. If you're not falling down every now & then... you're not going fast enough....

Im really not sure... Never seen a rod break like that before.. It was a new piston, rings, & pin. (About 4 hrs old). Clyinder looked perfect when I replaced it.
