I am partway into this build already, I figured I should start a build thread on here as I am pretty excited about this one and wanted to share my progress. I bought an old pre unit drag bike that had been used and abused and altered over the years into something that was used for show and did the occasional burnout (despite being in pretty bad shape as far as maintenance and wear). I decided to rebuild it from the ground up into a pavement and salt eating machine and take it back to it's glory days. Plans include racing at the local drag strip (with 5.5" Mickey Thompson slick and chain primary with drag gearing) as well as Bonneville (with Avon V-rated tire and Bob Newby belt drive). I want to drag it this spring, and bring it to Bonneville this August, so my hands are pretty full between this and my Panhead chopper project. Some pics as of today

Tubular alloy gas tanks I made a week or two ago, total capacity is about .96 gallons for both tanks, way more than needed for drag, and enough if I decide to run methanol on the salt at some point

Those tanks came out beautiful, Im curious what kind of alloy they are though.

Are they polished aluminum or chromed steel or something besides?

Excellent work either way

Now you're talking.. but that is a different bike...This has me thinking I need to finish my twin engine , twin turbo , with a later 955I 6 speed . I'm still trying to decide if I need to go for a drag bike or a salt bike since the engine and wheel design would be way different . Or maybe just a Vintage sprinter . Not sure at this point I just have the 2 650 preunits , A set of bronze flywheels , A late model Triumph engine/clutch with a jack shaft where the crank used to be and a frame .

Salt definitely salt. 1/4 mile can't compare to 3 miles flat out.

When i first come to America, I'm amazed to see bikes such as this. In Soviet Russia i rode Ural. My bike is best in all of Petropavlovsk. My brother, Nikolai, he say to me, "Mikhail, you go to America, they make you rich like czar, take many woman as lover, kill many bear". My brother, he is very wise, is greatest cook of borsk in all of Russia. So next day i wake up, sell my house, say goodbye to wife and children, and go to America to become millionaire motorcycle builder. Then in America, I go to job interview and they say to me "Mikhail, you are not for the job here, you are not the skills we need, you build bikes like poor child". I take that man and smash his table, i say "someday i will be greatest motorcycle builder in all of country, your children will wish me their father!". That day my anger is best of me. It is then i know i must learn better motorcycle building, so i study Triumphs of Mr. Malinky. Now i am builder of Triumph Motorcycles like Tyler! I write letter to Nikolai, he write back "Mikhail, your Triumph is like that of god, you will be millionaire soon! all of Petropavlovsk is proud for you! good luck brother! please send letter when you are president or maybe even czar! Hahaha! also, your wife is killed by bear". So i say thanks to Mr. Malinky for building bikes like this! When i am czar your family will be spared! Hahahaha! (is joke).

I am focusing on my Panhead these last few weeks as I need to get it done for El Diablo Run, but I haven't forgotten about my drag Triumph! Still getting things done on it, just got these wheels back in from Buchanan's

I believe this front wheel to be consummate beauty.

While it has appeared nothing has happened with this bike as I am working on building my Panhead for El Diablo Run which is coming up quick, not all is still with this build... Got my tires mounted, and also got all the parts in to rebuild my gearbox with the later style needle bearings instead of bushings.

The front wheel is crazy, I checked the tire specs about 10 times, it is meant specifically for a 2.5" rim, which it is mounted on. It feels like a solid rubber tire, it's nuts.

I already have a slick for the back! I have two rear wheels, one that came on the original bike that is a Mickey Thompson 5.5-18" slick, and this new wheel that is a V-rated tire for land speed (Bonneville) stuff. I can swap the wheels in just a few minutes.. The slick is not allowed at Bonneville. However it is allowed at any local track!

You guys RV it out to the salt? Or do you stay in Wendover?
