I suppose the 520 crank with the Wiseco big bore piston in a 400 would make it a 540 but I was reffering to just punching out a 520, thats cheap and easy.
The 400 and 520 are nearly the same, especially in price ($5998)
I'm going to Europe in the fall on a quest for a manufacturer that makes the pistons for Smets. Keith Bowen. An American vet racer and former Team Yamaha member did the original test ring on the 520 and he said that most of the world round guys use a 580 set up. I'm looking for a source on that piston and possibly a 700cc set up for my Adventurer. A few years ago I built a 720cc XR650L Honda for a friend in Madison and that bike was smooth and torquey. I'll post anything I find out in this forum for you guys, thanks, Eric
