Steve, nice point - I'm pursuing the sealed airbox path (Ok as sealed as possible) and am now going with chicken wire at the nosecone and I'll knock up some kind of panel filter to sit at the cross bracing just behind the headstock. In that way the airbox will have loads of filtered air to draw on and I don't take up airbox capacity with anything else. Having said that, your over the throttle body solution / reality check warrants being considered at the very least ! cheers Neil |
