okay, so i got home from the bike expo on sunday, and the bike started leaking coolant.. checked it out, and it was a split radiator. i took the rad. off the bike on tuesday, and dropped it off at a radiotor shop this morning to see if it could be repaired. when i called him at lunch time, he tells me the radiator has eaten itself from the inside out, was leaking in several spots and was unable to be repaired. ive since ordered myself a new one to be delivered, no matter what the old rad. is fecked. problem is this, the mech said he thought it was either caused by mixing coolant types, that have not mixed well, or maybe been mixed with water that has caused it, or electrolysis, caused by a bad earth somewhere. when i was taking the rad. off, i did notice a bit of white/grey coloured residue in the pipework, and on the rad cap, and figured it just needed a system flush, which i will do when i put the new rad on on saturday. now the bike is 2000 model SV650S, with less than 30,000Ks on it, as as far as i know the previous owner took good care of it, as have i. its spent a fair amount of time sitting around in the last 6 months due to me being injured, but i was starting it frequently to avoid a flat battery and other related issues. anyone know the best way to diagnose this electrolysis thing, and best way/ most obvious place to find the bad earth? any other idea what could have caused the rad to eat itself from the inside, and how i go about fixing it? i need the bike back on the road ASAP, as the car has busted the radiator as well, and should be off the road too. the bike was worse, and i thought i knew exactly what was wrong with it so figured to fix that first... PLEASE HELP!
