Impressive job.
All it needs now is a nice stiff alloy frame off, say, an R1 to handle the extra power and you'd have decent bike.
Anyway, apologies to Wraith... I seem to recall saying (about 6 months ago), that it probably wouldn't fit.
Still think it's a guaranteed way of spending a huge amount of time, effort and money to produce something that'll sell for about 10% of what would make the venture worthwhile from a purely economic point of view. Fine if it's a hobby and you're intending to keep it, but this guy is clearly going to take a huge loss.
