Greetings: I am bigjeff and I did a cb900c bobber build a while ago....it was friggin fantastic to ride. But alas - I grew tired of my new toy and sold it. The buyer traded me a dilapidated old 1972 cb500 frame with a 78 cb550 engine with a fury springer and an invader front wheel. What? A NEW TOY to fuck with! I am excited.

So we begin on the saga of the cb500/550 springer chopper front- brat style rear hybrid. There is a reason I went with the swing arm and shocks in the back rather than go hard tail but I will explain that later.

Here it is being pulled out of the storage shed. It was there for YEARS AND YEARS......rusted bad.

So what is the first thing to do? Why take it all apart of course.

73402

Down to the frame - add new head bearings

73403

Now I crack open the engine.

73404

Parts EVERYWHERE!!!!

A 78 550 engine with 72 500 carbs on it? WTF? Thanks Randy!! lol

73406

Got new bars and a new tank. :)

73407

New dual headlights. (I want this bike to be like the ones I saw in high school in the early 70s). Dual rectangles it is!

73408

Chopped the rear fender:

73409

Sparkly silver to freshen up the rusted wheels and new rubber and tubes of course:

Fabricate seat area. The original frame was cut to add a king queen seat. It was way too low for me. I am tall and needed to go up. Filled it with aircraft style structure (which will be my electrical battery box under the brat seat. I also like brat seats cause' you can move around and keep monkey butt at bay:

detail view of aircraft style structure. All the electrics and switches will go on this triangular enclosure which can be accessed by removing one bolt and lifting the seat out of the way.

Frame/seat/front is DONE!! Off to the yard for a photo shoot!!! :clap for you:

Now I guess I need to work on the engine so it will do something but sit there and look pretty. Why not bore it out and put bigger pistons in there? A CB600!!!

73421

Stuck the crankcase in the frame. Gunna build the top end in the frame. Easier to get it in that way IMHO. Sneak up on it one assembly at a time. :p

73422

And last night - put the new rings on the new pistons and installed them on the connecting rods.

73423

Well - that is all for now. Got to do some more work so I can take more pics.

Later........bigjeff

Nice detail......
Is the area in front of the seat with no padding for you to sit on????? And the big large cushy seat for a fat chick with a big ass?????? Since you say you like ass...

Sure-----why not. lol I do like a big ass on a woman. Bigger the cushion the better the pushin' and all that. The flat portion will have the headlight on off high/low toggle switch and a ignition kill toggle switch. The ignition key on the left side triangle.

This is a small bike. Only room for one. Like I said, I am tall so my ass will be right over those new shocks. I don't think I have ever seen a springer brat before - but I have now! :confused:

Never to old for anything if you want to do it. I drive a tricked out firebird too. Going though my mid life crisis but I am ok with that. My dick still works so I am good. :)

I don't understand the gap in front of the seat... it just breaks the flow to me.

yeah - I get what you are saying. It was a compromise.

I am 6'4" tall and had to get the seat up and back to make the mid pegs work for me. I loath forward controls as I don't feel in control of the bike. That is my dirt bike rider dayd coming through in me I guess.

So - it was a function over form thing. The triangular metal box will house the small kick start only battery, the Ricks rectifier/regulator, ignition switch, power bus ect., and various switches (lights, kill switch etc.) I have led tipped metal toggles for that.

Didn't like that one huh. Yeah - not a real chopper. I get that. But suprizingly enough, that bike drew a lot of attention and positive remarks while out and about with the regular public. ChopCult guys are MUCH more selective. More of an art form I think.

Well - it is finished. Took it on a ten mile run and figured where I need to be for tuning ect. All in all I am real pleased. It is fun to ride and people stare. Lots of thumbs ups. :)

The two 55 watt headlights were a bit much for the charging system so I swapped them out for LED lights. Not a retro looking but I really like the look.7421974220

I also added some highway bars made from crap I found at Lowes. Used all-thread, union sleeves, and some nuts and washers.

It came out strong and very comfortable and useful.
