I thought I'd throw some pictures of what I'm working on here. Finally a section for bikes that don't fit under any particular label. Stay tuned for updates!

one part 1966 Honda CB450, one part 1970 Triumph TR6C

two bad frames can be saved to make one good bike.

not a bad idea, eh?

time to put them together

slugged downtube, sleeved backbone.

welded up. still needs to be cleaned up.
8/22 update:

$15 RM125 kickstand beats the solid steel $75 triumph stand all day long

needed to slim down the triumph kick stand mounting lug

kickstand success.

rear section

a bad stock Triumph rear section, some DOM tubing, and my Biltwell banana seat. (is that a 2006 Honda CRF swingarm I see?! madness!)

bend some tube

looking good!

ready to weld

cut the tabs off the original rear section and welded them to my bent tubes and cut the rear bend to size

make it all smooth and pretty

tig weld the legs on

mine on the right, an original Triumph rear section on the left. Mine is much lighter and narrower - perfect.

bolted on the frame.

front end

2001 GSXR 1000 front end

Found this complete set-up on craigslist for an unbelievable $250!

press out the steer tube after removing the lock ring.

spin the steertube down so you can use CB450 bearings

i hate branding.

fill with weld

grind it all flat

smoothed and blasted trees together.

I bought a beat up Triumph 650 bottom end for $200. The VIN is a fake, but the cases are either from a 1971 or 1972. I disassembled the cases and transmission and sent the cases out for glass bead blasting

Don't they look pretty? the head is one I actually won't be using, and the box next to my engine has all the guts I took out

need to clean out all that glass bead and media. Using "wurth multipurpose solvent"

crank out. sludge trap replaced. Pin torqued to 33 foot pounds. The bearing journals were within spec so I gave them a quick polish with some 1500 grit and proceeded to reinstall the rods with some new bearings. rods torqued to 28 foot pounds.

fancy (expensive) new english bearings. sealant on the seams and ready to go together.

bottom end coming together.

Timing chest is almost done. Don't forget those cam gear nuts are reverse thread!

transmission getting cleaned - just about ready to go back in.
9/14/12 update:

here you can see a pre-65 layshaft and a post-65 layshaft. I need the pre since my wheels don't have any interface for a speedo, should I decide to run one.

transmission back together. I actually swapped the layshaft with a pre-65 so I can run a tranny driven speedo (since I'm using GSXR wheels) You can see the speedo gear - the spiral gear interface)

primary drive going together

10/26/12 update

rear end

what up 2006 Honda CRF swing arm?

Used a CNC machine to make some steel mounts from some 3" OD 1/4 wall square tubing

Hello, windows 95

the endmill follows the dotted line

I think I see what I need!

got the mounts bolted to the swing arm and blocked in place to be migged.

a piece of steel plate to tie it together

sexy tig welds

oxyacetylene torch to bend the piece around the radius before welding it.

boxing up the underside

little bit of heat to shape

ugly-weld solid.

making a linkage anchor

after bending, bolted it on

tig welded.

mig welded

a diagonal tube welded for trianglulation
9/14/12 update:

this yellow factory CBR600rr spring is rated at 600lbs per inch. WAY too still for my needs.

cut that silliness right out

I used a bridgeport to compress the new Eibach spring from racetech. 400lbs is still a little stiff, but I'm going to ride the bike before I get a softer one.

I decided to run the shock the other way to make room for an oil tank. Rat fink valve cap. Something special planned for the gusset

Starting to feel like I'm the only one without a cnc mill in their shop! Nice start!

not my shop - a friend's, but the door is always unlocked for me. It really isn't necessary, but sure makes radius ends a breeze!

Lots of impressive things going on here.
thanks! i like to get "hands on" with projects. Every single piece of this bike is being made by me so I'll know how every part works.
updated: engine post has timing gears.
