WITH THE END OF LEADED PETROL, ALL BMW'S PRIOR TO 1985 WILL EVENTUALLY REQUIRE CYLINDER HEAD CONVERSION FOR CONTINUOUS LEAD FREE USE. THIS WILL HALT THE VALVE SEAT RECESSION AND RESULTING DAMAGE TO THE TOP END THAT WILL EVENTUALLY RESULT AFTER HIGH SPEEDS AND PROLONGED USE ON LEAD FREE FUEL. THIS NEW PETROL BURNS AT A HIGHER TEMPERATURE AND ABSENCE OF LEAD DEPRIVES THE SEAT/VALVE INTERFACES OF ESSENTIAL LUBRICATION.

FORTUNATELY, THE SOLUTION IS STRAIGHT FORWARD AND PROVIDES A GOOD OPPORTUNITY TO INSPECT AND OVERHAUL THE TOP END OF THE ENGINE AT THE SAME TIME.

YOU MUST SEND YOUR CYLINDER HEADS TO MOTOBINS FIRST (THIS IS NOT AN EXCHANGE SERVICE). WE WILL CARRY OUT THE WORK REQUIRED AND RETURN THEM TO YOU WITH ALL THE REPAIR/MODIFICATIONS YOU REQUIRE. THE TURNAROUND TIME IS NORMALLY 10 -14 DAYS FROM RECEIVING YOUR CYLINDER HEADS.

WE STRONGLY RECOMMEND THE USE OF A NEW TOP END GASKET SET TO SUIT YOUR MACHINE, TO PREVENT OIL LEAKS. ALSO THIS IS A GOOD TIME TO CONSIDER RENEWING VALVES AND INLET GUIDES AS A PRECAUTIONARY MEASURE AND TO RESTORE PREVIOUS PERFORMANCE. IT ALSO PROVIDES AN OPPORTUNITY TO CONSIDER FITTING ELCO HIGH TEMPERATURE VALVE GUIDES. INCLUDED IN THE MACHINING LABOUR CHARGE IS RECUTTING THE INLET VALVE SEAT WHICH DOES NOT NEED REPLACING. HEADS CAN BE BLAST CLEANED. PLEASE CONTACT OUR SALES STAFF ON :-  01775-680881 OR EMAIL ukorders@motobins.co.uk  BEFORE SENDING YOUR HEADS FOR TREATMENT.

RETURN CARRIAGE WITHIN THE UK BY INSURED CARRIER IS £10.00 + VAT. @ NET COST.

ALL WORK AND PARTS ARE GUARANTEED FOR 12MONTHS FROM THE DATE OF RETURN TO YOUR DELIVERY ADDRESS.

THIS SERVICE IS RESTRICTED TO UK CUSTOMERS ONLY

WE URGE YOU TO INSURE THE CYLINDER HEADS WITH YOUR TRANSPORTER AGAINST LOSS OR DAMAGE. REMEMBER FINS ARE FRAGILE SO PACK THE HEADS APART AND ENSURE THEY ARE WELL WRAPPED..

FROM 1985/86 ALL BMW'S CAME WITH LEAD FREE VALVE SEATS FITTED IN THE FACTORY FOR ALL MODELS, AND THERFORE THEY DO NOT NEED CONVERTING. IF YOU ARE IN DOUBT AS TO THE EXACT YEAR OF MANUFACTURE OF YOUR MACHINE, CALL US WITH THE MODEL TYPE AND ENGING/FRAME NUMBERS.
