I met my childhood friend Jörg from Germany. Remembering my beautiful days in Sande was great.We met in Las Vegas, next day we went to the Hover Dam and drove around Lake Mead. What a beautiful day we had.

The two skinny guys, reuntied after 30 years! - Not so skinny anymore ;-)

What an engineering marvel! Just east of Las Vegas is the spectacular Hoover Dam

Last Race Of The Season

2011-11-21T01:09:00.000-08:00

Now we have a long winter ahead of us until the first race next year in May. This season we joined the SCTA Club, 'Milers' and met lots of nice people, of course we gained lots of experience too. Our best official time was 116.345 MPH, we are pretty happy with the result, even though we had the potential to do better. After the '56 Triumph project, the racing bike "Kursed" will go through a complete rebuild including new design sheet metal components. The new 2012 Kursed V2 build will be published here after April, our goal is to have the total redesigned racing bike ready for Bonneville Speed Week August 2012.

Norton 16H Front End

2011-10-09T00:11:00.000-07:00

This one belongs to the "Redesigning The 1956 Triumph" project. It is a very nice heavy duty pre-war girder with rebound springs that i'm reconditioning.

The threads are fixed, some rust has been taken care of and new 26 TPI nuts installed. Next i will need to make some friction plates and then it will be totally striped/cleaned and ready for paint.

Not bad,

Revving up to 6800+ in the 4th Gear.

2011-10-02T23:35:00.000-07:00

The new rebuild gearbox and the sprocket combination worked well. Honestly, at the end of the video I rolled off the throttle seeing it was still revving up, I figured i had enough for the day..

Final Ratio?

2011-09-28T01:30:00.000-07:00

Rebuilding a different ratio gearbox..

Large sprockets are cool, only if you have the hp though..

Now we need to test the bike with the new handlebar design and gears.

Mods Continue..

Still to do;
Electrical & Wiring Parts, number plates, lanyard-type fuel shut off valve, brake lines, install seat.. probably more?

Making The Oil Tank - Part Two.. '56 Triumph Project

2011-04-22T21:20:00.000-07:00

This tank is going to have an integrated oil cooler. The triangular tube/duct that I'm making will cut through the tank from the top left front (intake) to the lower right back (outlet).

Fins on the air duct will reduce the inside temperature, especially the oil returning from the engine will directly land on the cooling duct instead of the warm oil.

The vertical angle/form of the duct has been designed aligning to the gas tank's bottom for efficient/continuous air flow.

Announcing Bonneville Project 2011.. '52 LSR Project

2011-01-09T00:38:00.000-08:00

We will be at the Bonneville Salt Flats this summer for speed week. The bike I will prepare is a 1952 Triumph. It will be this engine which is actually a '52 6T, I probably will use the swing arm frame for another pre-unit project.

The matching Pre-Unit rigid frame.

Little stand i made for the Triumph projects.

New Work Table

2010-12-17T01:33:00.000-08:00

One work bench was not enough so i had to build this one. 8' x 3' with 3/8" thick steel top, perfect for sheet metal work. It also has a sliding welding table underneath.

Jockey shift components in detail

2010-10-23T18:32:00.000-07:00

To order this kit e-mail alp@sungurtekin.com ..

All hardware is 18-8 Stainless Steel including the threaded rod shift linkage for higher Tensile Strength.

The entire jockey shift set up is designed to bolt onto any Harley Sportster engine 1988-2003 without any permanent modifications. The position of the handle is adjustable, it can be moved from the front to the very rear.

Precision hand made.

The Jockey Shifter

2010-10-22T01:35:00.000-07:00

This shifter design that i fabricated for "The Whip" got positive attention and several orders so i decided to post some images of its build progress.

It makes it easier to design it in 3d first, so i can figure out the proportions and get a printout for the 1/1 scale diagram. This way the hand made components look more precise.

My client who ordered this one will install it on a Flyrite "Smoking Gun" as well.

Below you can see the beveled edge, I used a hand file to achieve this form.

To the left is the lower arm, connected to the main bracket.

The clutch lever housing bracket is probably the most complicated component of the set-up.

Yeah, I know, not so safe... this machine is unbelievable strong.

Lower arm bearing housing.

2010-09-29T00:23:00.000-07:00

The gas tank will look like this. The knee indents will be a bit of a challenge but this detail is what makes this design.

Below is the tail which is actually the extention of the gas tank , Yeah it's not going to be a traditional cafe style.

Here is what i've found;

2010-02-05T01:31:00.000-08:00

Original 1936-47 Harley big twin springer:

What a beauty! It has a 1" stem.

I already received all parts for its full restoration.

Castings? Yeah still there! But the paint is not in good shape, so i will take care of that next week.

New welder finally arrives :)

2010-02-03T21:48:00.000-08:00

It's a water cooled 300amp TIG ;) it should do the work.

With the old springer on,

2010-02-02T23:04:00.000-08:00

NOW it has a 36-48 harley big twin springer. I will publish the restoration/installation pictures of the new springer pretty soon.

Oil tank

2010-02-02T22:46:00.000-08:00

The oil tank for the Whip is specifically designed for it so it surrounds the frame tube and fills the gap evenly between the rear fender and the engine.
