Twin cam project : V-Twin Forum: Harley Davidson Forums

Hi everyone great to find like minded fxr enthusiasts here. This will document my twin cam drivetrain swap into an fxr frame. I bought this basket case 1982 fxr that had no motor but did have a title and most of the parts in boxes. Not being able to afford to build a proper shovel motor and wanting to have a unique machine, I decided to go the twin cam route. The bike did come with the stock trans and I opened it up to find a bonus andrews gearset inside. So I sold the trans and primary setup to fund twin cam parts. I will be using the '02 and up bagger swingarm, rear brake, trans, and motor. I will be using the stock shovel harness for the basics and a thunderheart stand alone for the ignition. This bike will have no turn signals, mirrors, handlebar switches, etc and will be low with 11 inch progressives out back and lowering springs in the stock 35mm forks. All wiring will be ran thru the frame and hidden the best i can. There will be no modifying of the frame except relocating crossmembers for the trans to fit. I have shaved the forks of the reflector pads and fender mounts and plan to polish them. This will literally be a paycheck to paycheck build so progress is slow. Heres some pics so far:

I look forward to following your build!

Although I don't have the newer swingarm yet i wanted to see where the new crossmembers needed to go. I' going to weld in a section of 1''x2'' rectangular tubing between the frame rails right in front of the oil pan. I'd like to make the rear one removable in case i ever need to take the oil pan out, so I think I'll weld some tabs on the frame and use some spacers and a piece of 3/8'' plate that bolts in.

Made a new crossmember and got it welded in

Found this Road King tank on craigslist for $50 there is a 1.25 inch hole in the bottom and the guy selling it had no idea why? Also had a piece of leather over the fuel pump hole? Paint is mint I almost feel bad cutting it up but i am going to narrow it about 4 inches. I think its way too wide for the look im going for.

Got my new swingarm also

Since fender struts go for outrageous money on ebay I am making some out of 1.25 inch aluminum bar. It will be turned down to 1 inch to fit inside the frame and all mounting bolts will come in from inside the fender. Going to weld the rear two holes shut so it will all be smooth. Heres a before shot.

Getting rid of the fork lock to clean up the frame some.

Very nice project Matt .....
With the 'upgrade' swingarm in use, will you go to a 39mm fork set-up sometime in the future?

Was trying to visualize what color(s) would look good on your scoot ...any hints?

Gloss ocher frame / flat black tins ........

Nice work!

Waiting for payday.

MATT82FXR · 10-03-2012, 04:22 PM

Thanks for the positive vibes guys. Lucille-I'm thinking a burnt orange/copper frame with gloss black tins. Not a fan of chrome so most of the other parts will be polished aluminum or stainless. But I'm a trucker so I have lots of time to daydream about color schemes so my ideas will probably change 10 times before i make up my mind. Oh and lately im thinking I will use Buell forks with gloss black 13 spoke mag rims. I love the clean look of the 35mm forks but I know I wont be satisfied with the handling. And the Buell forks use a 6 piston caliper and 13.5'' rotor.

So i have been focusing on small details that most guys won't notice, but I enjoy making them. These things are so time consuming but to me are worth it. I was hoping to have this thing rideable this year but thats not going to happen. Thankfully I get to ride this in the meantime

I welded a washer to this socket to accept this push switch that fits inside the left handlebar end.

It is held in by a setscrew and will be all hidden under the grip. I'm using soft rubber bicycle style grips so when you push in the end of the grip it starts the bike
