Well been looking around here for a week since I picked up my 1976 cb550. It was a find on craigslist about 15 min from my house. Got it for $900. Not sure if thats good or bad but after seeing some Jap Bobbers it's what I wanted.

Plans are to hardtail it with most of the other bobber stuff. Figure it out as I go I guess.

Here she is the way I got her. Started with battery and kicker so I guess thats a good start.

Here she is at the end of day 1

I'll try to keep this updated and hopefully I can get some help from you all if I need it

why did you cut the engine crade pipes???

Now your engine alignment points are WAY off.

Don't forget to put slugs in the pipes to ensure strong welds.

Why did I cut the pipes? I don't know! Looked like thats what I needed to do.
I'm going to bolt the motor back in to make sure it all lines up before It gets welded.
I got slugs for the connections.
Again this is my first attempt at choppin up a bike I'm sure it will have plenty of .......character lol

Thru the motor back in and lined up everything. It was all crooked without it in.
Friend of mine is turning down some slugs for the tail. I have bigger tail diameter than the original frame diameter. He's going to take 1/8" to a 1/4" off of half to get it to fit in original frame

Take some angle iron and brace up the frame. That way it will be easier to locate your motor mounts. Also you could leave the swing arm in to make sure the rear is square and the trail is good. I left my swing arm in until the rear end was completely welded in. Then just cut it out. Might save you the head ache of squaring things up later on. Good luck. should be fun

Well got half the tail tacked up. You actually got to think this stuff out.

awesome man. i love my apes. have you ever had them on a bike before?

Jinxracing · « **Reply #11 on:** July 02, 2010, 11:15:41 PM »

Are you going to lower the front so the bottom of the frame is parallel to the ground? (I vote for "yes"

)

seaweb11 · « **Reply #12 on:** July 02, 2010, 11:21:54 PM »

Dude, you can't just cut a bike in 1/2 and not come back with photo updates

Ogri · « **Reply #13 on:** July 03, 2010, 02:48:18 AM »

What's your new trail measurement now ? Looks like it'll be more than 6"...it might be a bit hard to steer at low speed.

COMB2 · « **Reply #14 on:** September 14, 2010, 05:31:35 AM »

Well I finaly got it to a spot where I could take it off the lift and roll it around. Fail!!! Yea the trail is way to long the front just flops when you turn it. The tail is also to low which don't help with the trail. I need to chop the tail off and restart. Another part that doesn't help is I found out at some point the front of the frame was lengthened to add 4" and the forks extended to give it a chopper look, that don't help with the trail problem either. Now the solution? I found a member here not to far away that had the same frame properly hartailed and I picked it up and I'm on the right track now. I'll have to post up new pics of it.
I do have a good part bike now

Amazing how your project has turned out so far

With respect to your sight gauge, aren't you concerned that "someone" may give it a yank. I have visions of fuel spurting out over a hot engine.

hahahaha wow......

I like it!

DaytonGuy · « **Reply #18 on:** October 12, 2010, 05:06:26 PM »

Any chance you can take some pics of how you set up the electrics under the seat? How are they mounted inside? Where does the wire harnes enter? etc. pics would be GREAT!

You bike looks pretty sweet.

Well the electronics are kind of just thrown in the container. I did how ever coat the inside with several layers of liquid tape. I drilled holes in the side and used rubber grommets so the wires would not rub. Not sure if it's going to get to warm in it or not but I see lots of guys putting them in oil tanks. Most of the wiring on this bike is gone. I keep all the main stuff like the regulator, solenoid , fuse box ect. Snipped all the wires I didn't need and ran new with connectors in case I needed to take it all apart. I then shrink tubed all the exposed stuff. The 3 switches are kill, headlight and starter. They are just toggle switches

Retro Rocket · « **Reply #24 on:** October 22, 2010, 08:18:55 PM »

Good luck trying to tune that bike with those pipes and also get used to shorter valve life, no back pressure is not a good thing..
