Not sure if the riders from North Down area and around the country that we have now got a supplier of Rock Oil . He has just opened a new shop in Ards . Company is small but willing to deal with motorcycle clubs and anyone small local fixer . He has said if anyone who contacts him directly he will work out a discount for them , just mention you are a BMW owner or GS owner . Here are a few items he has . 15/50 synthetic , 20/50 Semi , 20/50 mineral . Chain lube, Brake cleaner , Silcone Spray , Carb Clean , Fork oil . I would give phone number buy his card has slipped down between car seats and my big mits can't reach . So will take car apart to get it , or contact me and I can pass on his details . Nothing to do with shop , fella just gave me good deal on oil for Goldwing .. Hope it's of some use to locals .
