Only a slight amount.  I mainly modified the frame.  I ground down the top seam and welded it shut.  I also ground down the two tank mount studs about 1/4" and narrowed the stock rubber mounts.

Do you think I could get away with just beating the seam down? grinding and welding back together are a bit farther than my skill set allows me to go

I really don't see how you could beat down that seam.  It's very thick metal.  You could probably grind it down to the top of the pinch welds and then beat in the bottom of the tank.

would that weaken the frame any?

Yes. Do it the right way and be done with it.

I'm testing some paint that I will be using for my engine & wheel hubs.  Since I come from an aviation background I'm testing to see if the adhesion of paint is aided by the commonly used Alodine 1201 chromic acid-based chemical coating.

I have two kinds of 6061 aluminum test strips, shiny and bead blasted.

First I used Metal Prep 79.  It's a non-flammable multi-purpose phosphoric acid-based cleaner and pre-paint conditioner for most metals.  Application leaves the surface chemically clean and corrosion free.

After a good water rinse I let them dry and then applied the Alodine solution.

I also tested two strips with only the Metal Prep and no Alodine solution.  If the paint holds up well with just the acid cleaner than maybe the Alodine can be omitted as a cost savings step.

The paint I'm testing is VHT High Temp engine enamel and VHT Wheel paint.  Both are cast aluminum color.  I'll let them dry and then bake the engine paint at 200F for 1 hour.  The wheel paint needs no baking.  I'll test them by scratches, hammer blows, and chemicals (brake cleaner & gas).

Well the engine paint is dry (waited 7 days like label says) and will bake 200F for 1 hour.

I tested a couple of pieces with the wheel paint (doesn't require baking) and the non pre-treated pieces didn't fare to well.  The paint flaked off very easily.  However, even on very shiny & smooth pieces that were treated the paint didn't flake.

Will do final testing in the next few days.

Also testing out some rally stripes on the tank.

Bought some Chroma base+clear paint.  Red and white.  I have already shot on the white in prep for making my stripes.

I'm also mounting my EX500 Ninja twin piston caliper.  I had to make a new mounting plate out of some thick steel plate and weld it to the Ninja plate.

Big thanks to djelliott for the tip!  The EX500 rotor mounts to the CB350 rotor hub just fine.  I used stock ninja mounting bolts (but will need to shorten).  They are special shouldered bolts, but plentiful on ebay.

Great thread, explanations, and pics.  I'll definitely be following along.  Will you please explain a bit what "seam welds" are and why you did them?

http://encyclopedia2.thefreedictionary.com/seam+weld

The bike has spot welds on the top tube (under the gas tank).  I had to grind down the seam to fit my gsx250 tank and weld the seam back together.
