CB360 from rat cafe to real bike!
« on: Aug 19, 2018, 20:37:36 »
I bought a CB360 a couple years ago that needed some work

this is how it started when I got it, recently survived an electrical fire due to lithium battery without the properly upgraded charging system


I built a makeshift workbench and began the dissasembly - motor was in decent condition but I opted for a rebuild, glad I did - you'll see why


some in betweens:


moved the project indoors to my friend's garage where we have a welder, drill press, other tools and some bikes in various states of awesomeness


did some mock up of the frame after a lot of input from members here about the rear suspension that I should have never attempted but did anyway


painted frame and then began assembling the parts and engine into the frame:


PAINTED it:


and the results are below with specs!

Just Some aluminum angle, cut it to mount over the upper shock mount and holds the tag, stop/tail and tag light

Just noticed the coils, look cool !

Might need a new set of coils myself, and like the look of these, where are they from ?

When you say modified exhaust header, can you go a little more in depth?

Thanks

if only I could find some fuel hose that didn't yellow after a week, and figure out why my K&N filters turn gray and dry out after 2 days :(

You can get tygon pvc fuel line in a bunch of colors, just not clear.  I use the grey stuff.  Motion Pro brands some.

Bike looks great.
I used a set of cj headers, and welded on about 18" of straight 1-5/8" tubing. I plan to merge these and use a single cone engineering muffler or just two cheaper emgo mufflers angle up similar to the supersport bikes
