I haven't a clue where to find my created thread list... I thought I had put the pictures of the 650 setup in here, but apparently not.... once I'm done packing up more stuff in my shop in preparation for a huge move and retire to the house for the evening I'll work out getting some pictures uploaded of the progress. The Ducati wheels are finally sorted into the build and the exhaust is getting close to finished. When I run a load of parts and boxes of house stuff to my brothers place this afternoon I'll grab some new pics of the progress as well. The carbon bodywork looks stunning so far despite the loads of finishing work yet to be done, it's actually starting to look like a proper bike! The engine angle wasn't right to start out so new mounts were made, rear mounts are in the process as of yesterday so hopefully some Tig welding tonight and a little bit more drilling should see them finished up by tomorrow. Hilariously all the rear mounts of the Wormburner frame, for the AO Bandit engine had to be lopped off with a plasma torch to accommodate the new mounts for the 650 engine.

My brother and I have been back and forth about a forced induction solution. I want to see a twin screw blower, he thinks a turbo works better for ridability... so last night as we were discussing plumbing and such for either option, it became apparent we're just going to do BOTH, and compound a turbo through a supercharger with a resulting 6-7psi at peak boost to keep the supercharger from working hard enough to be a hot air pump. Air to water cooling (basically a huge heat sink) in the plenum the way the 'busa guys have been doing it should keep it at a reasonable intake temp no matter how hard it is ridden since the blower will be a huge source of heat in the intake, especially running it without an intercooler since there isn't really much space to run one in the first place, and the more plumbing the more of a pain in the ass it'll end up.

First things first is getting it sorted as is with the PC5, as the winter inevitably sets in and I'm settled at the new shop I'll start digging into the forced induction solution and hopefully have it on the dyno around the same time the turbo bike goes in as that is down to a few small things and it's ready for tuning, what little will even need to be done for that. An evening after hours at a once glorious shop in the capital city running in the forced induction bikes with the staff we know so well should be a fun time.

Found a picture from a few months ago of the chop as the old Ducati wheels were being swapped out for a different set (swapped for all black, no yellow Scrambler stripe on them) so the correct factory decal wheels can go on a Scrambler and bring it back to its former glory, and give me a blank slate for whatever color I want if I don't just leave them black.

Im sure youve done your research and all but from what Ive read about the 650s, they wont take much more than 100 HP or so. stock is around 65-70HP depending on year and I imagine even a small compound blower setup would put you in the 100+ area at6-7 PSI. You planning on blueprinting the block and making something more sturdy or just reinforcing the internals as best as can be?

Bodywork looks really good! engine looks like a good fit too, I though it might be a bit small for a big 1000cc frame but it looks good there.

(most of my reply isn't directed toward you or CF guys at all, just, kinda stressed out and tapped out a monologue of shitty attitude here. ;) )


My patience for this new layout is running thin real fuckin' quick. It's like VS purposefully made a mess of CF to attract more nitwits and push out the people who used this site for a decade plus that are looked at as assholes because we know what we like and like what we know. These emoji things suck too. :(

6-8psi on pump gas isn't much for these engines, it's all the guys cranking it up to 110-120+ at 9-12psi that really ruined the reputation of the equivelent of an open deck Subaru shit block that easily took 6-8 all day too. Getting greedy is the issue here more than the balance and construction of the engine. My '07 is worn in decent and proven to be solid so I'm assuming a combined boost level of barely anything more than what D series Honda's and older open deck Subaru engines handled for years and years, should be fine. If it isn't, it'll go kaboom, I'll eat shit at 50-80mph (again) and I'll move on with life if I live through yet another highway speed crash. Keeping intake temps way down, knowing what kind of turbocharger to use (things progressed a ton in the past decade, way beyond what the first 650 turbo setups ran) and how the numbers work with compound boost setups, it'll inevitably be a setup that once it is set at a certain boost level on a certain fuel, there's not much that can be done aside from just run it the way it is and keep an eye on EGT and IAT to ensure I'm not going to hole a piston, crack a sleeve, or create too much positive crankcase pressure or wash down a cylinder. I'm sure it'll get sorted on the dyno as to how far it'll go as I'm going to get a few different blower pulley options to swap around and play with wastegate spring pressure until it's happy. I'll run pig rich to start with and dial it back as the boost levels are tamed at WOT pulls last of anything.

The flat track guys have really pushed these things to the limit and it seems 110-115 is the peak of them on a standard bottom end and they'll handle that for a season or two at least. I'm going to be running for smokes and riding it like I would anything else with no rear suspension so the times it does see full turbo and rev range will be few and far between when I've got a 200+hp turbo GS and a compound induction diesel V8 to play with if I want to really hammer on something that makes all the cool sounds and torque numbers. I think most of anything it's just a giant middle finger to the guys that DID push these engines to the breaking point and then told the world they can't "handle" the boost. Well, news flash, open deck blocks don't appreciate double the factory power output. :rolleyes:

Finally snagged some pics of current status of the build. Right now we're figuring out the exhaust solution and working out the seat setup. Engine mounts are nearly done as well.

149940



That's engine position sorted now.
149941



Headlight and gauges will be as simple as possible to keep that clean look going as best as possible with an EFI engine in there...
149942



Waiting on a Ninja 500 radiator to replace the mockup of drtbike radiators paired to meet the same size and shape.
149943



It's got some pretty sexy lines going on now. I'm really liking the direction this build went.

That long and low look is pretty fitting for a bike that'll eventually be one of the cleaner builds I've had over the years.

My brother truly is an artist in a craft of brute force. These engine mounts (and now a kickstand!) are pretty much the beginning of the end of the hard parts required to make this a running and riding bike. The excitement is real.

i like that, it harks back to the bikes the term "streetfighter " was actually coined for
That was kinda where some of the idea was concieved from with the bodywork, the old Back Street Hero's mag cover made me consider more aggressive lines (American hardtail builds tend to have swooping, rounded lines) that still hold some Kawasaki influence as well as pay homage to the very beginning, the roots if you will, of what got us started into calling our machines a StreetFighter. Riding on the shoulders of giants.

:ROFLMAO: I've been called alot of things, sexy is not one of them. Par for the course. :ROFLMAO:

You know as well as I do, being in central Wisconsin, a mere hundred miles from the home of Harley, if this thing is going to catch attention from the guys that build choppers it better put a smile on their face that someone used anything but a Harley engine in a rigid frame because it was done so well it can't be flat out criticized over being a "jap bike". Telling people it's an English frame and Italian wheels with Japanese forks and engine results in puzzled, quizzical looks of interest. The guys I know that build iron, all think this thing is coming together in a way that'll be incredible by the end of it. Quite a badge of honor in a sense to stand out from the crowd in such a way.

I'd still like a nice Milwaukee mid section with a little sprinkle of Italian on both ends! indian kinda got there with the FTR and I likey!
