Could it be that you have got old stock Brian ? what bike was it for ? if its unusual it may be slow moving stock ie old stock .
I bought some stuff direct from DC plastics recently ( tried Les but by the time i got a reply the stuff was already here direct from DC
)
Side panels for a 74 KX 125 , inner rear gaurd for RM 125S and a rear gaurd for a 1980 XR 250 . I was very happy with the fit and the finish of it all , DC is as far as i know the only ones who make these particular items and postage was very fair and very fast .
In the past i have had a few shockers from DC but i think the quality is improving and their inventory is 2nd to none
Sure other outfits make higher quality finished products for limited models , Joan said the other day that those flash YZ plastics are drying up and the moulds are now worn so further production is unlikely
Remember the early days when you couldn't buy anything but NOS (if you could find it ) or generic plastics
I have some fibre glass moulds the late Barry Senn had made to turn out glass fibre fenders for RM A /B models Early KX models and 75 RH and RM 125S side panels .
Dc do fill a niche in the market but yes its not always perfect .
Its a pisser that you got a dud Brian , why not contact DC direct , maybe they have a new run with better fit and finish ? got to be worth a shot .
If they dont get feedback about this sort of thing they will probably continue producing the same none the wiser .
