Mornin gents. OMG a real live 660 owner. Quick hold him down so we get some bloody dimensions out of him. The entire planet of 600 conversions into 400 engines never measure a god damn thing. It is always, "the 600 rods are 3mm longer than the other rods', 'the other rods are 2mm shorter than these rods' and you will never find the word millimetres used. All joking aside Mr @660, we very pleased to make your acquaintance, and we appreciate your generous offer. We being Mr Ruckusman & myself. Though the cost of shipping anything from Canada would scare the bejeesus out of even a hardened Aus Post shipper. Now as for the New Project Binky, and no it will not be a Thai drag bike, but thanks for the great suggestion @kiffsta, I bought an FZR 250 cylinder yesterday for the princely sum of 158 JPY ($1.90 AUD) from Jauce.com. Now I know what you're thinking, "Who cares about that, why did you say 'an FZR' and not 'a FZR'". Well the letter "F" is pronounced "eff", and it is the vowel sound that determines whether or not you use 'an' or 'a' not the spelling. Anyway back to the topic, thanks to the encouragement of @ruckusman this Fizzer Cylinder will be used for a medical experiment. If all goes well it will then be stored in the hope chest until I can find an FZR250 to fit it to. As for the poor R4, I am ........... waiting.
