how many hours since it hydrolocked?
Did you run it with TL?
What CC domes and what cylinder?

It hydro locked the last time it was ridden due to TNT pipe and short water box. Then was dried out then ridden for a while. Ran great the whole time then was taken to the shop to have TL installed. Never ran it with TL. Has pump gas domes. Discovered the damage when installing TL.

It wouldn't happen to be a DASA 10MM 1100CC with 48cc domes?
What gas are you running?

Okai. Still no any further on what CC domes you are running. Have seen 2 DASA 10mm 1100 that looked a bit like yours (one with 8 hours, from brand new, everything) and one very respected rider, builder and tuner who had one of the 10mm 1100 tells me that its Deto from to small pump gas domes. (48cc on both those engines, with european pumpgas 99oct RON)
I would contact your engine builder and get their view on it or DASA.

I'll check the domes to see what size. Everything was done by DASA and I assembled

Why do you ask this?
I had this exact engine do the same thing.

Welcome to the world of detonation.
That's what caused it.
Might wanna rethink your timing curves and what color your gas cans are.

Mine was pump gas premium at 185 psi compression, OEM ignition with MSD enhancer.

I don't understand why people run 7-8 heat range plugs on pump gas on a high performance engine ??

I'm actually surprised more people don't do this. With 170+ comp on pump gas advanced timing and 7-8 heat range plugs and clear or light colored gas cans.
Big reverse jetting and I see this being a common problem.

I have to giggle a little about this!! You say DASA build engine?
Did it look something like this perhaps? Was it due to a pin failure that the bearings were fused together? Did you have lots of vibrations?
And your engine looks something like this?
This was a DASA assembled 1100 with 8h on the clock, from NEW. 48cc domes stock charging ignition.
I followed the builders advice and used 48cc domes to make sure it was setup properly for pump gas 99 oct RON - but I had issues with front plug coming loose during riding. DASA send me new dome and new o-rings to try, to make sure the tread tap wasn't loose. Tried it but didn't help the issue. I inspected servereal times, but no sign of deto.
What exciting things did you discover when tearing down your engine? What domes did you use, and what crank? Was DASA of any help to you?

Estimated 10-15 Hrs, 48 cc domes, comp was checked at install and found to be@ 200psi. Double checked with builder and was assured it would be OK.
Timing curve, jetting etc all recommended by builder
Wrong little end bearing blamed for failure
