New 73 CB200 Caff Build

[hecklejk]

Well, I spent about 2 hours out in the shed yesterday working on the motor... specifically working on removing all of the stripped scews (both case screws and internal motor screws). Everything was going great until I tried to pull the 4 screws that secure the Point Base to the Head, 2 came out just fine but the other 2 already had stripped heads!!



Being that I do not own an impact driver, or a stripped screw remover I had my work cut out for me!! I grabbed my flat head screw driver bits and my 3 Lbs hammer and went to town tapping away!!! After about an hour I had the 2 stripped screws in the Points Base out, so I moved onto the Shift side engine cover which had 75% of the case screws with stripped heads. Thank god I got new Allen head bolts for the case screws!! Now I need to find 2 screws to replace the Points Base screws that I had to demolish to remove!! Can I just take the stripped ones to a local hardware store and find a similar screw?

I continued on removing things and was able to get the Right cylinder head cover off without any issues!! The next step is a bit confusing to me, I read the manual but do not understand what to do Next... any help would be greatly appreciated!! I have never rebuilt an engine before, so this might get a bit interesting!!

 Cheers

yes you can just go hit up the hardware store for the replacement... a trick that will help you get them out... take a punch and put it in the center of the screw you are try'n to extract... then SMACK it good with a hammer... this will stretch the threads of the bolt, break any loc-tite loose, and make it much easier to get out!

Thanks for the tip! That is actually what I ended up doing!! I took a meduim sized flat head screw driver bit and put it center mast in the screw and WHAMO!!! once it was locked into the screw head, the screws came out quite nicely!!

Did some work on the engine rebuild this weekend, mostly cleaning up the shift side engine covers since I ran into some issues getting the cam chain off (see post http://dotheton.com/index.php?topic=8542.0)so that I could get the top end apart!! spent about an hour cleaning the 30+ years of gunk off of the outside and inside of the engine cover ( GOJO scrubbing wipes are awesome for this!!!) then took some steelwool to the covers to get the residual clear coat of and to scratch the aluminum up to accept the paint. After cleaning up the covers, I applied one coat of 500 degree engine paint and I think it cam out looking pretty good. I forgot to take a before picture (which I always forget to!!) but here is the finsihed product (after 1 coat of paint)

I have noticed that a lot of the projects on the forum have names, so I have decided on a name for my project. I am offically naming this build ~ "Project Bee Sting" ~ I think it fits for 2 reasons, 1. the colors I have chosen for the bike are Black/Yellow, and 2. It seems to sting me everytime I work on it (i.e. one problem after another)...

Sorry for the lack of recent replys!! May has been a really busy month for me. I have not made much progress on the bike since I still cant get the wrist pin out of the shift side piston... but thats on another post. I did have a chance to get some paint work done on the motor, here are just a few shots of what she looks like at the moment.





I guess the next step is going to be cleaning up the frame and painting it, think I am going to have to take the engine to a shop to get that stuck wristpin out....

Well, it has been quite a while!! I have been really busy this summer what with getting married and all!! I have also been very frustrated with this project, and given up on it twice... I am now however back to work on the bike, and proud to report that I was finally able to get the stuck piston pin out of the connecting rod! This week I am planning on smoothing out the ridge in the connecting rod that was left from the seized piston pin. I am still looking for a gasket set on ebay, so that is really all that is holding me back on completing the motor rebuild. Once I get the bike done, it is going to have to go up for sale though... The wife and I have been talking and I think we are going to be moving to England, and the cost involved in importing this bike to the UK is astronomical... so I figure I can just sell this one and find a good runner over there.
