I myself would wait....I myself will never run Wiseco again, as the last one I got, the ring lands were wavy...and if you ask Motorrad his opinion of Wiseco, he'll give a similar response, and then some!
Another reason I myself could wait, is living in New England, it's still rather cold in the 20's and 30's , and snow on the ground....I could wait easily another 3-4 weeks.
Who knows...maybe another member on here has an extra Wossner they'd be willing to part with, so you can proceed with your build....give it a little time.
