Woot there it is. Good deal Jim. Looks like a full on project can commence now.

Got all the scaffolding off the back of the bike, here's what I got up for grabs -

Front fairing -



Crash bars -


Two floorboards -



Forward controls w/floorboards -


Saddlebags & bracket (maybe off a Rebel?) -



Sissy bar (off a Rebel) -


Saddlebags & sissy bar may be spoken for - if it doesn't work out then like everything else it's all free, just cover postage (from here in Canada).  Lemme know =)

Picked up a tank today, it's taken one for the team but it should pop out (any suggestions on how to do that would be gratefully received) but inside is spotless, no rust or varnish at all.  And that means no MEK, and that's a wonderful thing.



It's a K model tank and that's fine by me.  Although the bike is an F, I prefer the styling and lines on the K tank and love the gold pinstripe.  Got a colour scheme in mind, and I'll definitely be incorporating that gold pinstripe into the design.



Bike-like.

And here's what I pulled out of the air filter housing...



Gotta hand it to the little guy, that looked snug.  If I was a rodent shivering away in a Quebec winter I'd've made my crib as comfy as possible too.  Sorry fella, you're evicted.

Also checked compression today -
Cyl #1 - 165psi
Cyl #2 - 170psi
Cyl #3 - 165psi
Cyl #4 - 165psi

Pretty damn good.  I mean, shit - factory is 170psi +/- 14psi according to Clymers.  This thing's barely lost anything in 35 years.  Gotta hand it to those Japanese, they sure know how to build an engine.

I've read that hot glue on a dowel rod can do wonders for popping such dents. No experience at it, however.

I've tried the hot glue but I think the bigger the surface you glue to it the better. Like a drink bottle with a bigger 1" cap, I think cbrianroll posted a pic of that in Hurco's TW200 thread now that I think of it.

Also heard of people using a sphygmomanometer inside the tank and inflating it, or baking soda and vinegar to pressurize the tank and pop out the dents that way (careful not to bust the seams)

Well the orderly line of people queuing up by my garage door for a beat-up 80's era burgundy front fairing with missing indicator never happened.  Stunned silence?  I know I know.  I couldn't believe it either. 

Pulled the carbs out again now I know it fires, bench synched them, cleaned out the airbox and filter.  I've realized it's a hell of a lot easier to install (and remove) these carbs by only attaching one accelerator cable (the pull one, not the push one).  Of course both should be attached but I'm wondering if it's a complete no-no to leave the push cable off - temporarily.  I basically need to get this bike through a safety exam (hmm, ironic) and then will be pulling everything apart again for the build.  Bad idea?  If that cable snaps then I'll answer my own question in dramatic fashion I guess...

Can anyone tell me if these carbs are stock?  Looking at Clymers it says (if I remember correctly) that the CB750F has either VB 42 A, B or C.  These are 42 E.  Anyone know what the difference is?

Cheers Irk. Any idea what the differences between the carbs are?
