I think back in the day some states titled based on when the title was first issued vs when the vehicle was built. Once the title showed 1970 it stuck.

Danny, what you're saying is titles were issued when bikes were sold so a '69 model could have a '70 title.

The frame and log book(reg doc) for my 76 cb750 was first reg in 78 in the uk. I don't think they had sold all of the f1's when the f2's came out! nos!

I haven't had any time to start on this bike but I did spare a couple hours and picked up an 80's GoldWing in running condition for $500 yesterday. Looks like I'll have another bike to play around with too.

I'm starting to get back into this bike again. I rebuilt the Goldwing I mentioned in the last post and sold it on so it has a new life. Now back to this bike.

I think to keep myself involved I will commit 30-60 mins. a day to this project (hopefully) I work as a full time auto tech so I have only so much time to put in. I'm going to push this one in tonight and rack it up and get back to it.

Okay so I moved my Harley off the rack and went outside for the K0. It's like 5 degrees outside and the rear brake is stuck on.....I grabbed a rubber mallet and beat on it a little and she loosened up. Pushed her in and racked it. Lifted it up and the damn cylinder seal is got a leak now. Damn it! Rack isn't even a year old....Gotta call Handy in the AM and see what they will do I guess. Still lifts up fine just a little noisy. I set the lock and dumped all the air so whatever it's good for now.

So I've never took on such a big project. Any suggestions for this one? Should I fix it enough to start it then tear it down and build it back up? 

A little background, got this bike from a co-worker when I worked at Honda. He wasn't a tech but tried his best to get this thing going. He brought it to the shop and an old tech that worked on bikes before Honda went into the car business supposedly helped him put it back together and set the timing, etc.. I think he re-ringed it and had the cylinders honed and replaced a bunch of studs. I don't know but a bunch of screws are hacked the thing leaks oil pretty fast when you crank or attempt to start it so I know something wasn't put together correctly. I want to strip it completely down to the case halfs, inspect and replace/repair as needed and then paint and re-assemble. I don't want to worry about what was done by the PO I want to KNOW for myself. He said the owner before him drag raced it and modded it, etc.. :/

I would like to find and put the correct K0 parts on this bike. I don't care how long this takes I want it to be "right" 

Anyway this is how it sits today

Cool project, nice frame number too. It'll be interesting to see how you bring this back to life. Subscribed!
If you like it, then you should ride it.

I think the bike should be fully thawed out tonight  :P

I think I'll try and get it to run at least first. Is it bad for the engine to run it without pipes? I have a beat up pair of RC pipes that came with it but I'm lazy and don't want to throw them on just for a 10-15 second engine run.
