Hello everyone,

I’ve been away from this forum for a long time now. I use to have a gen 1 zx14 that I installed a stage 1 rcc turbo kit on but I hit a deer with it and the bike ended up being totaled. Then I bought a H2SX which was a nice bike but I always missed the zx14. I held on to the H2SX for a while as I started a business making parts for it. Last year I was offered a good price for the H2SX so I let it go and decided to build another zx14. I found a completely stock 2023 zx14 with 48k miles on it for a decent price so I bought it. The miles didn’t concern me as I intended to go through the whole bike anyway and I have no intention of selling it.

I’m fairly far along with the build at this point but I will start from the beginning and post updates when I have time. The basic plan for the build is a stage 2 rcc turbo kit, fully built motor, maxx ecu, and flex fuel setup.

The first step was to get the bike home, pull the motor, and build a fixture so I could mount the engine in my engine stand. Here’s some pictures.

• Disassembled the engine
• Built a front support bracket for the engine so I could split the case.
• Split the case
• Inspected crank and rod bearings
• Inspected transmission gears
• Inspected cams and buckets
• Ordered the first batch of parts

I found that the oil pan had a bit of a jelly like oil buildup on it, the bearings all looked like they were in good shape considering the amount of miles on the bike, the cam lobes had some damage, cam buckets have some wear, some of the valve clearances were 0 on cylinders 1 and 4 so it’s unlikely the bike ever had a valve job done, valve seats are heavily pitted, transmission gears look excellent, output shaft seal was leaking, output shaft collar had a groove wore in it from the oil seal, cylinders look good.

•Due to the damage to the valve seats I decided to send the head out to SRW Performance Engines to have new valves installed, full port job, and carpenter valve springs installed.
• Due to the damage to the camshafts I decided to try and get some used ones off eBay. I tried twice, the first set was not what was pictured in the listing and the second set had the same damage my cams had plus additional damage from poor packaging so I decided to order a new set of .395/.395 cams from carpenter racing.
• The output shaft collar was on back order so I pressed it off the output shaft, cleaned it up, replaced the bearing, and reinstalled it.
• Honed the cylinders to deglaze them.
• File fit the rings.
• Installed new rod bearings into wossner rods.
• Checked rod bearing clearances.

Wow, my Gen1 ran great although the compression was barely in spec. My dream is to turbo a Gen2 sometime in the future. When I see what you guys go through, I think my project will be a lot less ambitious but I'll follow this one through to the end and learn what I can. Did you have a look at danmin's threads?
