72' CB350 - First build.
« on: Nov 01, 2010, 16:51:11 »
Hi all,

think it's about time i make a build thread for my CB350. Since it's the first bike i've ever owned and worked on, and also I'm away alot for work, it'll be a slow build, but i will update when ever new stuff happens.

Here's what it looked like when i picked it up:




During teardown:




First try at making knee dents:



Cafe racer seat making:



First mockup, lower part of frame is cut  because of extensive rust. Hopefully I can make a new lower part or repair it. If not i'll get a new frame or possible a donor bike.



Engine before rebuild:



Top end apart:



Lower part:



Engine work included:

All new gaskets
All new oil seals
New pistonrings
New valveguides
New camchain and roller.
Lapped valves
Starter plugg off
All old screws is now stainless steel allen heads.
Polished intake and exhaust ports
Camshaft, rockerarms, rockerguides, camhousing, oilpump from donor engine with low miles.
All parts painted and put back together.





Polished hubs and brake plates:



My try at speedo background redo:



Still a lot of work to do, but it's comming along nice and slowly.

Last picture is of the engines i normally work on:



Thank you for a great site with lots of usefull info and beatifull bikes.

Excellent start to the thread.  I also really like that engine stand.  I need to build something like that before I take my head apart in the next couple months.

Wow! Really great work on the engine! Did not expect those to be the next pictures immediately following the "before" pics.  This should be a treat to follow.

Shit man, was the frame really rusty enough to justify chopping it in half?

Hope you have some skills....looks like you do.

Thanks for the comments on the engine guys, appriciate it.

The engine paint is silver and black from MOTIP:



As far as the frame goes, yes it was pretty bad. Had several cracks, and the tubing was nearly impossible to weld on, due to lack of thickness. The bikes has been used by p.o. all year round and snow, rain salt etc, has left its marks. If everything failes I'll get another frame.

Little fab. work done, bushings for rear swing arm:



Working on carbs right now. Cleaning, new screws and a little paint, pictures will follow.

Waiting on new fork seal and gaitors, so i can rebuild the front end. Pictures will follow.
