    Sorry to hear about your Dad. I've had to bury both of my in laws in the last 8 weeks in Texas, real hard on the wife. We just got back home Saturday night from burying her Mother.

    Let us know how you come along on getting that 400A running again.

    got a lil work done to the 400, dad said the carbs were a real bitch to remove, which is why he never got em off. :ear took me all of 10 min and they were on the bench. :lol3 i heard pine sol does a great job as a carb cleaner, so picked up a couple bottles and disassembled the carbe and gave em a good 2 day soak. removed em and hit em with power washer, blew em out with compressed air and re assembled em.

    i gotta admit, the pine sol worked, they came out very clean.... and the barn even smells squeaky clean.. :lol3

    put the carbs back on, but there was no clamps on intake boots or air box boots... no idea where they went... or if they were even there from po. slapped in a new set of plugs, but had to remove a broken plug from plug wire boot thingy, which took more time than re assembling carbs!! damn plug was stuck in there but good. got a charge on old klr battery and slapped tank back on (with old gas), hit the button... and the damn thing fired right up!!:eek1:D no smoke, no weird noises, no leaks.

    it's in need of a good cleaning, but will worry bout that later. gonna give er an oil change... and pick up a correct battery this weekend. it needs a good bit more work, but at least i know i got something to work with now.

    i'll update again when i get it off the lift and take er for a spin. and still gotta find that damn title.

    Sounds good but please don't run anymore of that old gas through it. Write down the VIN, take that and your Dad's death certificate to DMV and request a replacement title for the lost one.

    Good luck on getting it back on the street.

    Man, sorry about your Dad, mine passed about 3yrs ago & I still miss him. If I were you I'd get that 400 on the road, figure out somewhere he would have liked to gone and take that bike for a ride.

    i am goin tomorrow to pick up some fresh gas, gotta get some for mower anyway. problem with title is.... dad didn't put it in his name. we picked it up and the guy signed and gave us the title, but dad never went to license branch. the guy never dated it, so... if i can find it... i am straight.


    thats easy, he wanted so badly for us to go on one more ride anywhere, destination didn't matter. just wanted to be able to ride again. :deal

    i will get it sorted and ride it. i put some clamps on carb boots and changed oil today. put air filter back in and also installed air box cover. fired it up and it runs smooth as silk, responds well with throttle. last time it was registered was in 94. can't believe it runs so well.

    still got the 400 in barn and it runs well, found the title and bill of sale too. i know it's been a couple years, but still plan on getting this thing legal and got a trip planned. a trip we started many years ago thru st. louis in route to branson. we started it, but foul weather prevented us from finishing.

    hopefully this summer.... i will finish it. :deal

    when i do... i will update.... stay tuned.

    not forgot bout this thread just not got to work on the lil bugger in a while.. today though i did a proper cleaning on carbs..

    [​IMG]

    they weren't really that bad but pumper was completely clogged, which explains why it was so laggy and un responsive now is all sparkly clean..

    the front brake system was fubar. no pressure and leaked... also piston siezed. we totally tore it down and cleand from lever to pads. a rebuild kit got it working just like new!

    hope to get it back together and running by next weekend. plan to put some miles on it this year.. :clap

    i had planned on getting forks done today... but dagone it was cold today! i did get something done though. i got forks off in preparation to change seals..

    [​IMG]

    but seeing as i had easy access to engine i decided to get valves adjusted..

    [​IMG]

    everything up there looked like brand new! and valves were still in spec. i did adjust the intakes slightly to get em to .005 as the .005 was tight but i am sure a .004 would have fit perfect. i didn't bother grabbin a .004 gauge as i just set em to loose end of spec.

    the inside of valve cover didn't even need cleaning.. just wiped off mating surfaces and put cover back on.

    [​IMG]

    after installing valve cover i also finished installing front brake after rebuild and bled again and it is good to go.

    getting closer....

    I've got the tail rack and hard bags off of one of those, if you are looking for any.

    No, the bike's long gone. I don't have any pics, but I could take some in the next few days. Cases are black, missing the chromed protection rails, say Honda on 'em, and I have the key.

    Tail rack is complete, but needs some polishing up. It's the same set-up as in post #11, just black bags and not such a shiny rack.

    that would be cool, the destination was branson. dad played bass in a band for 20+ years and always wanted to go there. i didn't care where we went so branson was fine by me.

    we made it lil ways south/west of st.louis and stopped for night at a motel, which was a cool place... the entire office area was covered with pics of all artists that have stayed there over the years. and every room had plaques with the names of the artists that stayed in the particular room over the door and on wall. i don't remember who stayed in our room and didn't have a camera back then (round 1990). it was on a major road, a highway or state rd leading towards branson. i would like to find that place too.

    we got up following morn to a monsoon that was not going away anytime soon. we watched weather channel and rain forecasted for next few days... so... we decided to turn back for home and do it another time.

    we never made it back..... :cry

    I had a 1980, I think it was cb400a, it looked more like the f's. My grandfather bought it for me as a leftover in 82, it was the orangish red, not blue.

    I had that bike until 3 days before I turned 21, when a bus pulled out in front of me.

    It was a great little bike, good for about 85 IIRC, only problem it ever gave me was the timing chain.

    Typical Honda, it never failed to start, handled pretty well, rode okay, good mileage, I miss that old bike.:cry

    i been workin on it here n there gettin it more to my liking. all original parts are on a shelf and will be kept. the wiring just unplugs... nothing cut!

    the rear 18 with a knob has been giving me fits with rubbing, but after removing fender and raising shocks to highest settiing seems to have fixed that. and made the trip to license branch and got it plated. was a bit of a pain... and 2 trips but is done!

    getting closer.......

    the 18" rear wheel just wouldn't work out so had to go back to stock 16" i did find an 80/20 in a 16" though and it should be here in a couple days. but i was able to put round 300 miles on the ol girl over the weekend. it runs much stronger than i thought it would, and is super easy to ride. and had zero problems..

    [​IMG]

    had no problem keeping up with traffic either, and pulled hills easy.

    the lil thing is smooth as silk too and fires instantly! think i am gonna dig it!

    Glad to see you got this running. I learned to ride from an uncle of mine in the 1970s and he passed away about 10 years ago, riding right up until the end. Lately my aunt has been waxing nostalgic about how she misses riding, but she would have trouble shifting; I've been thinking about on of these for her lately, as there seems to be a few on ADV.
