First SBT 951 motor siezed at about 25 hrs, threw rod thru case. No expanation from SBT, but did send warranty replacement. That one went about 20 hours, then wrist pin circlip (which is WRONG style, too loose, and prob installed incorrectly) came loose and made its way thru engine. Caused seizure of mag piston, and caused weld to crack on crank journal.
Since out of warranty, I got a chance to see SBT quality first hand:
-Non-matched cases, .004 out-of-round bores for main bearings. (but this is fine according to SBT)
-Crank case filled with excess sealant from SLOPPY join. Sealant squeezed into bearing and seal areas, as well as windage areas in crank case.
-Crank taper on mag end looks to have been pounded with hammer. (I had to fix this myself to get flywheel to locate true.
-Attempt at helicoil repair pulled out and had to be re-done by me.
-Rave valve bellows incorrectly installed, not allowing valve to close completely. More sloppy work that user had to repair.
Not to mention the obvious that SBT could not assemble a motor to even make 30 hours. Thinking SBT? Don't do it. Spend 400 more and get a properly rebuilt motor with OEM parts and matching cases.
P.S. I'm sure you won't post this, but I think a reply is at least in order.
