It took me a while to find this site, and this is my first post.  Seems like a lot of knowledgeable folks here and a good place to tap into some knowledge if needed.  So here goes....

A few days ago, I bought/traded for a 1980 CB750f.  The bike did not run, and all the cable controlled functions were frozen and did not move, nor did the brakes.  Trans felt ok.  Tank had some light rust spots in it and smelled of old gas, though it was dry.  It was a gamble, not knowing if it would even turn over(dry locked), but I thought it'd be fun so I brought it home.  

What I've done so far.

First I pulled the seat and battery/box.  Next I pulled the airbox back so I could remove the carb bank.  The air box  had a mouse nest in it and was full of straw, so I cleaned/washed that out after I pulled the rusted air cleaner/spring out.  I cleaned the intake boots and blasted the plugs.  I put some oil in the cylinders and with the plugs out rocked it back and forth in gear-Good,the engine is free.  I will start on the carbs prolly this weekend and get those cleaned up.  Plan is to see if the thing will run first, then go on from there.  The odometer has 21k on the clock, so the engine should have plenty of life left in it if accurate.  I'll replace the fuel line, and run gas from a clean tank to do the test fire(no pun intended, heh!).  I should note that the oil is full and looks new.  Total gamble I know, but I think I can make it run.  I'm not going to spend a dime on it until I know it will run.  In the mean-time
I'm also dripping oil into the cables as I go to free them up.  I found a registration from 96 and 97-I'd guess those were the last years it ran.  I'll keep you posted as to progress and upload some pics as I have time.

 The last project I did like this(5 years ago) was a dry locked '81 Suzuki GS450 that had sat under a tree for 12 years.  I got that bike for free so nothing to lose.  I restored that bike down to the paint, then sold it after clocking an additional 16k miles on it, so it had 37k miles on it when I sold it, and it still ran and looked great.  In other words, I've been down this road before, but it's fun when you can take a pile of worthless junk and put it on the road again....Will see how it goes!
