Welcome to the Hummer arena!
What is "LSR" ?
The hummers race at Davenport Iowa. and Wauseon Ohio.
Twice a year. That's all. 1/2 mile dirt track. about 60 mph or better! We need more racers!

Please don't hack up any parts!

You mention 1955, 1956, and 1959.....WHY?

These engines are either 125cc magneto ignition, or 165cc with a generator ignition. These are good engines but for racing I recommend a 165 or 175cc engine from 1960 to 1966. These engines utilize a magneto ignition, and will save a little weight (no battery).

The rules for racing either event is very simple.... Just follow the rules. Call us for details. Must use a stock fuel tank, stock cylinder, etc. You can modify the exhaust and carb! Call us if you need the official rules....217- four 16- o7 three three.

Next you will probably want a larger carb, and a expansion chamber exhaust. Perhaps a porting job. And don't forget a Puckett stuffer plate, which will also aid in compression.
Once dialed in, you will want some tires that bite into dirt, going 60 mph into a tight corner.

Remember....Davenport and Wauseon are only 1/2 mile dirt flat tracks.....60 MPH is fast on a little hummer! Especially into the turns! Hang On!

Here is a link to a recent Hummer Race at Wauseon:

You will have to cut and paste the above link, or simply do a search on youtube for "Harley Hummer Davenport" , or "Harley Hummer Wauseon" .

Looking to start a build on a flat tracker to run at a local track just for fun..I know little to nothing about these 2 strokes ..owned a couple through the years but used them for trade goods to support bug twin stuff.
So , as I don' t want to hack up really good parts, and I have literally nothing.
Who on here might have a 55-56 motorthat is complete but needs a build..might even do a 59 but that knocks me out of running vintage LSR if I happen to get the bug again.
Any pointers appreciated, yea I am going to get the puckett pamphlet.
Who has the best parts and Manuel's for a decent price.?
My history , drag raced and LSR..up to nitro so I have a clue about working on stuff, new to harley 2 strokes not 2 strokes in general , scrambles and CC in the distant past .
Thanks Boog
