    New bike! CB750 dragbike

    You guys may not know me over here yet, but I've been lurking for a while now. Did some Tony's days last year... crashed my T etc... Shes back to normal now.

    Anyhow, I was working over at Popoli's when the owner called me Monday morning and said that the place was done and to get anything I had in there. The service manager and I got along great, and he tossed me his old dragbike and another cb1100 for some spares when we were getting all our gear out of the place.

    He built the bike from the frame up, and put it away in 1985 in the basement. ARD magneto, no battery, no wiring, no lights. Gutted. Solid mount rear suspension, reverse shift, bored out to 1250 with 29mm CR smoothbore carbs. I gave it a quick wipe down and it is PERFECT. Not a rusty crap-bucket like most old CBs. I cleaned the carbs since it was puking fuel when I opened the petcock (which were basically 95% clean), cleaned the points, and she fired up on the third kick! 4 straight pipe megaphones make my tuono sound like a scooter!

    Current project: Make her street legal, with a little less dragbike and more cafe style. I will leave the magneto on for ignition, and install a flywheel/stator/R&R/small battery to power only the headlight, tailight, and turn signals (of which I have none). Basically, I'm going to strip it down again to the frame and make up my own wiring harness.

    Anybody ever mess with these things? I'm looking on ebay for the stator/flywheel parts, I have boxes of spares but no stator Tires, brakes, electrical, paint... It will be a fun frugal winter!

    Ohh nice...clean that exhaust and that's about it. I love the looks of the bike. What is coming out of the right side cover? Almost looks like how a blower would be hooked up

    That's the ARD magneto. The way this thing sounds now, a blower would make me crap my pants.

    Wow, that rear tire is in for a world of hurt when you light that thing off!

    Hey Mosh - I remember you from Tony's ... gorgeous Tuono, throttle stuck over the hill in five, right? Glad you are ok but man I felt bad about that bike - it was soooo mint. Nice to hear you have it back to normal.

    I have some old Hondas and love working on them - never a modded drag bike but they are all pretty much the same.

    You will find a lot of help here -

    And they will love that bike. Cool stuff and good luck with it.

    Yep that was me. You'd never know she ever hit the ground now I've been to that forum for timing info on the magneto, but just registered there and haven't posted yet. I'll put the bike up there and see what they have to say. Supposedly he had this thing running in the 10's back in the day (on 70's tires!)

    The main issues I'm going to have are deciding which parts to order... Both front and rear masters are off of who knows what, the swingarm hasn't swung in almost 30 years, and it doesn't even use a key!

    Take that vintage beast to the drag track and see what she can do.
