they won't publish their cam specs, so a few people that are familiar with the 790 cams are calling BS on Thunderbike, claiming that they are produciing 790 cams claiming that they are a proprietary design and marking up the hell outta them, Thunderbike's response is "we will not release specs" which at first I guess didn't suprise me, but I don't know of a single person that's bought them, and I'm on 3 or 4 forums for these bikes. I know of a few people that told Thunderbike they wouldn't buy them without specs.
Seems to me they are losing sales because they won't release the specs, only BS dyno runs that don't mention the extensive headwork that was done to the bikes (Graeme told me this in an email), but they never changed the website to say that the bikes on the dyno had $1000 plus of headwork done...dunno what they could possibly do to the heads worth a thousand dollars...but they don't have any of my money.
