I've been screwing with this thing for years now. It's time to at least make it rideable. My goal is to strip as much weight from it as possible, warm over the engine, and make it look decent.

I was going to make an aluminum subframe, but it turns out that is currently just outside my skillset. Hacked and booger welded the steel 2 seater (biposto) subframe. The stock aluminum sub was cracking due to the weight of the battery and mess of electronics the previous owner stuffed in the tail. I considered a Microsquirt conversion but decided against that added difficulty since then I'd really never ride this bike again!

Soldered all the cut wires last week and had today to confirm it would start and then get the engine out to start tearing it apart. Guess I was a little too optimistic I could mess with every wire, delete all the relays, install the M-Unit, swap the RR, switch to coil-on-plugs, and actually have it start right up.

Spent a few hours trying to figure out why it wouldn't fire up and realized I had a spare ECU in there with no chip in it. Put in the ECU with the chip and no improvement. Doesn't seem to be getting spark. Disappointed level 11.

Got it! I thought one of the ECU pin outs was a power out to trigger a relay, but it turns out it was a power in from the kill switch (pin out 26 for future reference). Fired up and idled like crap. Smoked a bit though, but it did last time I rode it a few years ago. I need to be sure it is engine smoke, not wiring smoke. Anyway, she lives again, finally.

Some garage troll detached one of the coil-on-plug leads. Fixed that and added a few ground wires and she runs like Flo Jo!

I bought this 996 engine 11 years ago to stick in my 916. It's been sitting in the garage under a trash bag ever since. I dont recall it missing dozens of screws including the drain plug! No idea what condition it is in. If it runs great, otherwise I really only need it for mock up purposes while I refresh the current engine. Time to swap it in....

4 lbs of wiring, fuses, and relays gone. Another 2 lbs switching to coil-on-plugs. Goal is 350 lbs. Started at 405 lbs with the factory tail and Monster headlight amd guages. I'll need to add back some wires for headlights and signals.

I had a 900ss crank ready to send out for lightening which would stroke the engine to 1026cc. Internet says it's drop in, but the crank lightening guy said no. Skeptical, since there are many who have done it. Oh well, he's going to work his magic on the stock crank. It's in the mail.

I'm thinking I can beat that. Purchased some expensive fence posts and watched a bunch of YouTube vids so now I'm an expert. Let's screw some stuff up...

I tried to cut the header flange out by hand. Learned all about work hardening in less than 5 seconds. Wasted money on dremel grinder wheels to hog out the header holes. They ended up looking like shit. Decided to have them laser cut. I thought I could scan the header gasket and use an online tool to turn it into a .dxf file. Laser cutter didn't like that. Took a few days to learn real CAD instead of Cardboard Assisted Design.

Titanium welding isn't as bad as I thought it would be. Tight fit up is the key!!!! It's really slow going.

I bought a big shield cup and the collet it uses is way shorter than what I had and the one that came with it was 3/32" and I'm using 1/32" tungsten. Friday night and the welding shop doesn't open till Tuesday. Whataya do?
