Been a while since I've posted an update, but it appears I'm less than a week away from starting and getting on the water. I resolved the issue with not getting 2 beeps, after working with Nick at Westside Power Sports, it was the MPEM, no blown fuses, just wouldn't recognize DESS. I'm irritated spending $200 to get another MPEM, this ski really needed everything, I probably should have walked away, but too late to dwell on that.
I was delayed a few weeks getting media blasting completed because of an equipment issue at the place I go to, finally got that done a couple weeks ago, painted everything and assembled it last weekend. I prepped the hull recently to accept the engine and installed it today. Little tight with the auto bilge, but it's in and secure, wiring runs to a small switch on the steering to activate the auto setting, manual override takes a spot on the info center. Strictly piece of mind, I don't anticipate any leaks, just encase of major failure the ski won't fill up with water and hopefully would buy some time.
Running NOS clearance standard bore Wisecos, good quality forged pistons, I run them on the 97' GTX, takes a little patience to find them for $150 shipped. Fullbore did the resleeve, about $315 to get that done. SBT provided the core swap crankshaft, about $330 total including the shipping charges to AL. Balance shaft was in surprisingly good shape, seals good, but slight noise on the bearing on the weight side. I swapped it out for a NOS Nachi 6304 bearing, cost, $9.
Before dropping the engine in I set the timing using the degree wheel, and double checked the rotary valve clearance after getting the cover back from the machine shop today. I asked for a .007 shave on the lip and oring, they got it pretty close, now measures at .015, which is still .001 out of spec. But I'm not going to sweat it, I know it'll run fine, the 97' GTX, measured afterwards at .017 which is a big improvement from an initial .024 and .020 respectively on the GSX.
I went ahead and tapped the balance shaft area for a fill and drain. I used a 3/8" NPT tap which was perfect for the stainless cap I picked up. Little oil proof teflon tape to seal it up and red loctite on the M6 grub screw on the bottom.
The alignment tool that I bought last year worked fine, I was able to confirm I'm lined up. Carbs are rebuilt with OEM kits, new needle/seats and all stainless hardware. I checked the pop off and pressure tested, appears both seats lift at about 34 - 35 psi. Sealed them up in zip lock bags ready to install.
What's left....I need to finish connecting a few things in the hull, prime/test the oil pump on the bench, finish painting the header and remaining exhaust pieces, install the jet pump and add oil, grease fill the pto boot, install the the new HD ss hat and carbon ring. The add fuel and oil, charge the battery, then attempt to start.
