Although you've cleaned up your shed recently, it's not the biggest if I remember that correctly. Maybe you'll be lucky over on FB, as you'd need to sell 60 tickets in order to match the initial price you're asking.
Don't know much about this particular bike, but I think it's worth the money as it comes with a lot of great parts. In addition to that, I think I'd be patient and wait for someone who's passionate about this bike.
I'm also not sure if it would sell at the moment, even if you would decide to split it up and sell everything individually. Many awesome completes are for sale on here since... well, quite a long time.
As for the raffles in general I don't feel like we should go down that route on here, as this maybe the last place where real people still make good deals with each other.
