Jeff's 1938 UL Big Twin Flathead Chopper

 

Few things are classier than a flathead chop. That venerable side valve engine looks so right and purposeful, one can't help but be mesmerized by it. Jeff Leighton is no stranger to flatheads and was missing his old one when he started collecting the parts that eventually coalesced into this righteous machine. The cool thing is, as collectable as Jeff's bike might be, he still rides the snot out of it. Here's what Jeff has to say about his baby…

 

 

Over time I acquired all the very hard to find original big twin flathead motor parts I needed. I also found a good frame and a bunch of other stuff. I took all my motor parts over to Flathead Fern's and Fern and Sayer built me one amazing motor. Once I got my motor I started building the rest of the bike. I dug the NOS Wassell chrome fender and MCM cocktail shakers out of my stash. The original tank went on the bike with the sissy bar that I had bent up years before at Four Aces Cycle. I had a chrome VL springer on the bike for awhile, but it just wasn't right so I dug through Wes White's stuff and put together a pre0unit Triumph front end. My amazing friend Frank Kaisler helped me extend the stem to fit my frame. I found a set of NOS MCM covers and laced the rare 8-inch Triumph front brake to a super narrow WM0 21-inch rim. That front end topped with the square Flanders risers and the Z-bars I narrowed made the bike look like a million bucks.

 

Engine, year and make, model, modifications: 1938 UL Harley flathead with original 80" barrels and high-compression heads

 Frame: H-D knucklehead/flathead frame

Fork: 50's pre-unit Triumph front end with MCM covers 

Tire/wheel size and style: 18" star hub wheel in the rear; WM0 21" laced to an 8" Triumph hub and brake; Avon rubber 

Favorite thing about this bike: My favorite part of this bike is how reliable it is given the 72-year-old motor

Next modification: This bike is done in my eyes. It is perfect to me. Someday I will have a different tank painted for it, but I could never strip and paint over the tank it has now

Other mods, accessories, cool parts, etc: Original hard-to-find square set of Flanders risers for a Triumph front end; original Beck grip;  the first sissy bar I ever made (probably the best one too.) I got the old painted peanut tank from an old-timer named Ronnie. He was an interesting guy and amazing talent—it's a shame we lost him

Thanks to: The one and only Frank Kaisler. I am honored to call him one of my best friends. Wes White, Brent Anderson, Jed Levin, Bryan Garver, Fern and Sayer of Flathead Fern's

Killer bike, Jeff. Is that what you ride when you aren't riding around 2 up with Wes on the bagger?

Fucking beautiful! I dig the brit hydro front end of a flatty! Also, its easy to go overboard with color matched accessories, this is just about perfect. the kicker with the seat and grips are just enough to set off the paint. Very tastefully done.

I love the colors on the tank and what looks like a contrast between the flat base and the shinier flame design
