Hi chaps went up to my local airport (perth uk ) bought 20 ltres no questions aked , except he said bring a metal container next time din not mention a brass cap.
now to the important bit 20ltres @£1 83 plus vat @ 20% =£43.92
There grade is 100ll ithought it would be 103 apparently my engine is tuned to avgas.
I also bought shell super 99 @1.51 there appears a big differance in price
The bike i own is racer so perhaps lads who race KRs may be able to answer these questions.
i will have to check the compression ratio.can this be done through the plug hole ?cheers bob..
