Hi Furious,

I think I can help you.
You should select the "Blender Render" and not "Cycles" in Blender. Also forget the materials of Blender. The exporter and GP Bikes can't use them.
To give colour to parts, you have to UV Unwrap them. Now you can Export the UV Layout as a Image ( .tga File) and colour the parts with Gimp, Photoshop or any other graphic programm.
Back in Blender you select in the UV Editor the Texture you created. The fbx2edf Converter combines the parts and the texture.

You can repaint all parts later, you only have to know the name of the texture file, for example "seat.tga". So if you want that nobody can rapaint the seat, just name it "seat42.tga" or something like that.

For the first tests you don't have to worry about specular and bump map.

I hope I could help you a little. Very difficult to explain for me. Please ask if anything is not clear. Maybe I can make some sreenshots.

Ah, the Export options are imprtant.
Also make sure that the .fbx File is not to big. 6MB is the max with my computer. :)

Edit: You can color the parts with material colors (no textures are needed), but can't use specular, normal and reflection of the materials in Blender.

Hello! It's me again.
Need some help also. I have a problem with mounting my bike. Where should be 0 point in 3d model of lower forks? I made it on wheel axis, but in GP Bikes it's placed around handlebars. Clues?

Also I don't quite know how to make planes always visible. Some of the parts I modeled are invisible from one side. Some are also invisible even though I got normals fliped to proper side and. looks like outside is not set correctly.

Hi Furious,
the wheel axis is a good position for the 0 point. You can move the lower suspension in the BikeEditor by selecting Scene->Front Suspension in the Params window. Then grap the suspension in the other window and move it to the right position.

Well im sorry for being so ignorent about 2 stokes :P all i though was a 500 street bike would be around the 150bhp mark...

And dont get me wrong, i love small capacity bikes! My 33bhp sv650 (restricted) was an absolute blast to ride and although its a reletivly big step up, my Daytona 675 is the biggest bike id want to ride on English roads.

The last 500cc gp, 2 strokes, 4 cylinders, have more than 210HP for about 115-120kg, and all the power can be used only  on a ladder of 2000 or 3000 rpm until 17000 or 18000rpm.
Suzuki has made a 50cc gp, 2 cylinders, 2 strokes with 20HP at 20'000rpm
Honda made a 4 cylinders, 4 strokes, 50cc, with 22HP at 22'000rpm.
The theorical difference between 2 strokes and  strokes is that a 2 strokes can have the double of the power of a 4 strokes with a same volume (500cc 2s - 500cc 4s), because a 2 strokes has 1 explosion every crankshaft revolution and a 4 strokes only 1 explosion all the 2 crankshaft revolution, but in facts it's not like that.

Thanks :D

Im aware of the double capacity rule of thumb but as you said, nowerdays thats not necessarily the case.

Still a 4 stroke L-Twin fan though ;D
Hitting the apex is just a figure of speech, Don't literally hit it...

....just wait for the ryger engine.
125cc 2t, 70hp @ 17500 rpm

the wenkel motor is theorical the best by power.
One crankshaft revolution has 3 explosion => 3 times more power :-):-):-)
mazda power hehe

That's why we have plenty of wankel engines around us I guess :)

@Hawk: you may be glad to hear that many of the cons of a Wankel engine (and also some of the pros) are in common with 2-strokes engines. As the italians say: mal comune, mezzo gaudio :)

What like, needing a whole engine rebuild because you started it up for more than 5 mins :P

Haha! C'mon Matty.... You've surely got to appreciate the shear beauty and simplicity of this engine... C'MOOOONNNN!!! Hehe  ;D

Since they sorted out the piston seal wear problems I think it's now the most efficient and best design of engine there has ever been. Can't understand why other manufacturers have not developed their own versions now to be honest?

Just love that Wankel engine Max as I'm sure you expected. Lol  ;D

If I remember rightly when Norton first started using it in their JPS race bike(many years ago now) people were debating it's cc capacity because it was so fast? Am I correct?
That was indeed a beautiful bike with a beautiful sound, and SO fast!  ;D 8)
