    sad part is that all of those parts individually would bring super huge money on ebay, espically that crazy frame and that coffin tank. That is not just a weld on hardtail - that frame was fabbed around a stock neck. Cb350 chp frames are rare - there were some made but not many survived.

    Take off all that hardware store brass, put a proper tank on it,saw the pipes off, throw out that windsheild, and bring the front end up three inches and you would actually have a decent chopper.

    personally something this weird would actually be worth $1500 to me (if I had two nickels to rub together) - but I am a fucking weirdo as it is.

    Hehe...I love turbo intake manifolds....shape no concern 10 psi will push that air in there just fine.

    I have the same engine, or similar ( It could be a 900 or a 1100, mine is a 750) but that turbo is amazing....would that be difficult to build??<img src=icon_smile_shock.gif border=0 align=middle>

    It is not a 900 or an 1100 - it is a 1980 750cc DOHC. The bike looks to be built out of a K bike.

    They still sell turbo kits for DOHC cb750s overseas, I believe they are just the old Mr. turbo kits from the early 80's. Back then there were quite a few turbo kits for bikes, and it was not oncommon to see one - these days the only turbo bikes you see are new sportbikes.I am pretty sure the bike above uses an old draw through kit (a single carb is attached to the turbo instead of the turbo forcing air into the carbs.

    Turbos on early DOHC honda were so popular that Revell even made models of turbo cb750Fs.

    Making you own is fairly straight forward if you know your way around a welder. You need a header to drive the turbo, a steady stream of oil to feed the turbo bearings, a wastegate, an intake that will bolt up to the turbo, and a single carb that can handle the turbo. That hardest part is finding room for everything. Remember that Forced induction is "forced" so strange angles in the tubing is not as big a concern as it would be with N/A motors.

    Wayne and sons makes a log manifold for SOHC 750s, he may also make them for DOHCs or he can custom make you one. With all the little turbo pocket rocket cars coming out of the factories these days it shouldn't be hard to find a small turbo in the junkyard (Subaru WRX, VW GTI, Mitsu Evo, Dodge SRT4, etc...) or on the message boards. I got a friend who works at a subaru dealer and they take off stock turbos all the time. Old harley sportsters used to use a huge (40+mm)mukuni VM carb that would be easy to setup for a draw through application - my local harley guy throws these old carbs out so I have a few sitting around.

    come to think of it....why am I not building my own turbo

    ...i've got a '79 750K cafe project in the process of becoming turbo charged as we speak.

    as far as placement goes, i want the turbo hanging out there in your face...as it'll be muffled through the turbo and finished with a tiny cookie cutter, it'll look as sinister as it sounds! as of right now, it's gonna go rearward, right behind the left shock near the end of the seat tubes. it may sound slightly bizarre, but it works...well. the pipes will then be long and tucked and when wrapped, will look equally killer.

    i've got some photos of the very initial mock up, but don't know how to post an image. can somebody throw me a bone?
