The experience I had with a few Webras are they are a solid engine, a bit touchy on needle settings. I tached the same OS 32 with the same pipe on the Webra and got about 1K less rpm's. But this was on a older Webra 32 Speed, it ran very consisten on my FF Fazer but my friends OS seemed to have a slight edge using the exact same tuned pipe on his plane. Webras performance has reached a newer level of performance on the newer engines though. I would not hesitate to buy another.
