I didn't intend any offense by making the mothball reference.  I was just referring to your earlier post, when the project was on a pause . . .

So this thing got mothballed for a little while but is now in full build mode. 

You keep teasing us with this one.   ;)  It's a nice-looking design.  I can't wait to see it all come together.  The motor looks excellent.

oh man, no offense taken at all.  I'm totally not thin-skinned... this build has taken way longer than I ever anticipated.  Scope creep! The story of my life.

Which year is that 900 tank from? I'm curious as to how you mated the top end with the bottom end of the 750 tank.  I have a similar idea from scratch, but didn't know what matched up well.

ebay Ad said that it came off a 98 CBR900RR.  There will be quite a bit of fab to mate the two together - the CBR tank is a good deal wider than the CB tank is, so effectively what is going to happen is we will be extending the cb tank pan to match up with the CBR tank.  There will also be some hand fabrication in the front to extend the tank upper down in the front where the aluminum frame runs up at an angle on the CBR.

I'll get pictures as it comes together.

I thought the CBR might be a wee bit wider.  I like the idea.  It definitely will require you to finesse the two halves together.  Are you doing the metal fabrication yourself or do you have someone else handy with a tig?

One of my best friends for the last 20 years has a high-end custom car building business - he does some pretty crazy fabrication.. did a full-metal widebody Eleanor body on my old 68 Mustang convertible when the guy I sold it to lost his mind and decided a $400,000 show-winning Mustang would be cool.  So yes, I definitely have someone lined up who is handy with a Tig.  haha

That's a handy friend to have around!  Is your Cougar (pictured in your signature) a XR-7?  '67?

yep.. that's Rump Rump, lol.  67 XR-7 with an XR-7G hood (the car is not a real G, no sunroof).  351w with an Eagle stroker kit, twisted wedge heads, cam, longtube headers, 10 bolt toploader, 9" trac loc with 4.56 gears.  No power steering, no AC, NO RADIO, sound deadening material stripped out, trunk liner and spare pulled out.. STRIPPED, haha.  Weighed 3100 pounds wet with driver, and ran bottom 12's at the strip on street tires.  For the time it was pretty ferocious, nobody had anything really fast in the late 90's.  Lots of kids with 16 second Civics and 14 second Mustang/Camaros.

The windsor and  4 speed are out of it, plans are to swap in a crate 5.2L voodoo flat plane motors (the new Shelby GT350 motor) and a T56 with a whole bunch of Cortex Racing suspension pieces, some big brakes, a cage, and then give it the widebody treatment with all-metal wheel arches.

I bought it in about 1995, green with tan interior, no transmission, no engine.. but arrow-straight and no rust.  It was my daily driver once I finished the build, then I bought something practical (that didn't make your ears ring for a half hour after driving it) to daily drive and it's been sitting and waiting for some love since.

It should make some awesome power and not bad mileage with the new crate and EFI.  Gorgeous ride.

Now is that tank done!!??  ;)  Kidding.  Watching this one with interest.
