THE WORLDS FIRST EXCLUSIVE EXPOSE! water cooling
firstly, i started up, idled for a few minutes, and didnt stop to check the excessive noise from the gears.
suddenly bits went flying!
anyway. my exclusive. my piece de resistance
(brace yourselves)
THE WORLDS FIRST WATER COOLED MOTORISED BICYCLE
note the use of the ngk b6Es cus i needed the 19mm thread and it was handy
yep. thats a radiator
so. initial tests, at idle was, easy starting, and currently its thermosyphoning for circulation. a pump is in the works as we speak!
the blip up the road showed excellent bottom end power, with only a slight raspiness due to a slightly rich mixture still. still revs out nice but
the thermosyphon effect cant quite keep up with the demands of flow required at over half throttle. steam pressure popped my hose off. someone had to pedal 2km home
ive just clamped the hoses, so ill give it another go in a minute. if it lasts 5km i might keep riding to the radiator shop and try finding a standard cap fitting so i can fill it, blow off excess pressure, and have an overflow tank... otherwise i give up for a while and do something productive.
chose to avoid any squish band effect, just a hemispherical chamber, about 38 across by 8 deep. havent measured capacity yet. seems to work very well though.
