Try Scorton next to caterick the third Saturday of the month, better chance of getting a bike there more for the enthusiastic than market shite at rufforth
I go most times as it's only a village away from me.
It's good for bolts and bits but the main reason is that it is what my wife calls "A man creche", where we big kids can have a little ride to get there, then walk around giggling at other people's rubbish and playing 'name that brake calliper' among the garage clear out piles.
If there's an old R90s or R80GS Kalahari, at the next one that'll probably be me. Unless I get the Dax fixed
