ESE's works engine tuner

The Roberts Aluminium bike was at Wanganui and I managed to bleg Henks camera as we were having a nosey.

Here is a pic of the dimpling I was talking about.
Again I say, I'm not sure how useful it would be; just a thought.

You may recall Fits had a go at interpreting the Matt Oaxley interview which was in English witch was translated into either spanish or Itailian over the top I can't remember which. Well here is the Test .Strangely it is in Water injection spec. It has the water cooling radiator in the nose and slot for it. Yet the blub says it indeed as everyone (bar a few Me included ) uses about 3.5 liters per GP. So the puzzle remains.

Did Benson ever get back to your email Wob?

Just for a wind up, was reviewing a few old threads.

Its been a long time since a 4 stroke won a F4 GP so 4 stroke riders should cherish last Saturday, it might not happen again for a while.

Date was 2008

......... on no I was wrong .....

With 30HP two strokes appearing we know ... they just need to be able to finish races

Big carbs I can do without, but water cooling ....... now that would be fair ...

Just need another ten years to get them sorted.

Whoa slow down a bit, you don't want to rush like that

The transfer specs call for a area ratio between transfer port window and tract entry of 1.3:1 (main transfer).



The tripple port cylinder on the right has had the duct entry closed up to a ratio of 1.3, it looks very small to me but the inner radius has a better looking curve to it.

You could ask Steve
I think he built the BMS 851 based bike chassis as well?
Here is a article I have on worshiping, the sometimes false (esp if overdone god) of Speed Lightness.
It is an enjoyable read. The water buffalo bit is hilarious to me. Plus the magnesium axle why not. Ha ha
I note that this example of dimple drilling above maybe for oil cooling, but if it was a great idea why is no one still doing it?
The weight saving benefits would have been less than.err.... blowing your nose, or a quick one off the wrist prior to racing.

I added the TKM engine because it was in the same mag. They still do make Kart engines.

Measured the volumes of the transfer ducts.

Right hand tripple port cylinder with 1.3, 1.2 and 1.1 area ratios

Trans A = 24
Trans B = 16
Trans C = 8
Total = 48cc for all transfer ducts combined.

Left hand single port cylinder

Trans A = 40
Trans B = 20
Trans C = 8
Total = 68cc for all transfer ducts combined.

A lot of the fresh charge must be, being transfed from the crankcase.

...they just need to be able to show up to/start races

Fixed it for ya.

Kickaha bike has been out of action while Suzuki re manufacture enough valves for the GN to complete 3 race meetings.

He is also waiting for the next season of American Chopper to get some ideas for a tank mural.

Now that is some funny shit!

No they have got the valves in stock, they last 2-1/2 seasons of 11-12,000 rpm abuse before they let go except if you use aftermarket then they last 1- 1/2 meetings

I think the tank might stay

Tell you what if i beat you at Grey on the GN Bucket vs 2 stroke Bucket Challenge.
Will you then let me take it off your bike and shoot it a couple of times.
Then mount it on My wall as a trophy head next to the stags Thar horse possum and other animals i have er... Ran over in my ute?

[NordieBoy]

I agree, I'm happy with my chances with the plans I have. Just need another ten years to get them sorted.

2 strokes and cheese. Both better with time.

Looks like good results at some hard, fiddly work there. I've been thinking of having a play doing something similar.

I have an emotional response to ultra-detail weight savings like cored bolts and holes everywhere possible.
However, In working out my new subframe I sat down and worked out what the weight savings would actually be from drilling heaps of holes through the neutral centre of the square tube. I can't remember the specifics but it was something like 77 grams saved by drilling that would take all day to do properly.
One could spend all that time doing far more productive things to actually make the bike go faster.

Might do it anyway; just 'coz shit like that gives me a long, hard fat.

And what would the other side of the bet be?

You know, if you loose...

oh come on now, be serious
