I was reading Practical Sportsbikes magazine, specifically the AR50 100MPH project and noticed that the ESE thread was mentioned! I hope that they don't mind me posting this, it's advertising on their behalf so I doubt they will, but see the attachments for some sneak peaks.

It's a good build and I hope they achieve their goal, actually, it's a great magazine with lots of stink wheel articles and builds. We've just subscribed to the magazine too.

Anyway, congrats to ESE for attracting world wide attention as well as the welcomed input from Jan and Frits. It's a great thread and I probably spend more time on it than I do watching TV.

This was the very first post on the ESE thread in 08, could Thomas be nearly world famous.

Below, scraped from Chrisc's thread. is some video of F4 racing at Tokoroa last weekend.

Your the first person in 5 years to notice.....

We did manage to get him used to wearing company overalls eventually.

Why do you think it will fail, Dave?

Honda 2T race engines have used 105 ish rods forever, I could never really figure out why.
But using a longer rod and keeping the case vol without using a spacer would be a very good test to try.
Biggest issue from memory was that the Honda pins are much bigger than anyone else uses thus restricting availability of suitable rod kits.
I have made hardened and ground sleeves to use a longer 110 rod in a RS125 kart engine, that won alot of races, but didnt have a dyno facility at the time,so never confirmed the actual performance change.

Besides Samarin Rods for Honda, there is also 112mm rod from TM 144cc and TZ 250 110mm rod from 2000 onwards that use the same pin diameter (24) and width (16). The wheight? The quality needed, I don't know

At 50 seconds, a NF4 RS125 frame with a 2 stroke CVT set up. Does a 3.00s 1/32mile pass. I laughed

A NF4 RS125 frame with a 2 stroke CVT set up.

Its a Honda RS125 chassied drag scooter alright .... but why does the pilot hold in what appears to be the clutch? or could that now be the rear brake?

[husaberg]

1/32 mile equals 50 meters.

[Frits Overmars]

1/32 mile equals 50 meters.

Drag racing for me has always been 1/4 mile, or 402 meters in real money. It has been devaulated to 1/8 mile, and then to 150 meters; it's a pity.
But 50 meters? No need for an engine; I could jump that far (well, almost).

Another funny thing in that video: blocking the front wheel position at the start line. What's the use? I would be glad to have my front wheel blocked at a drag race. Then I could creep half a meter backward before launching. Those first 50 cm are decisive because they're the slowest part of the sprint. I could easily gain 0.1 second with such a 'flying start'. Blocking the rear wheel would be the sensible thing to do.
