The white bike was a stocker, 29hp. That's the bike that won the Wera GNF, they tore it down to the pistons and found no violations including the air box snorkel. It was the same way at Gateway sans the snorkel .
The 335 was a HUGE success. Road America is a long track, 4 miles around, many elevation changes. The front straight has a big hill at the beginning, they call t the asphalt dyno. On a 250 you need to up shift into 5th befor the hill, carry it up the hill then hit 6th. With the new engine it didn't mater, it would pull it in any gear. I had to drop the rear sprocket 4 teeth and could have gone 6 easy as it pulled through the gears so easy I was hitting redline in 6th at the ends of the straights. I can't tell you the hp figure yet but may lap times where about 9 seconds faster this time over last season.
One thing to note, with the added speed the brakes started getting soft towards the end.
As far as the build, it's stock 250 cases. 300. crank, wisco pistons, stock head, cams, carbs.
