Garrrr…. Looks like I've got a fun leak that (from my limited knowledge) looks like it is coming from the coolant system. Linked is a video of the jet stream. https://www.dropbox.com/s/r8xrf704rb3ug40/20140809_093623.mp4 For the moment I've bought some more coolant and refilled the radiator/overfill tank and taped up the hole with electrical tape to try and slow the leak… However, I've been unable to identify the part in the manual so that I can order a genuine replacement. The closest thing I could find to what I need is the following: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=231302029877 But for what it is, I think the guy is asking for too much. For the more mechanically inclined, do you a) Know where I can better source the part b) Think it looks complicated enough to pass it onto a professional. From my assessment, if there aren't any special tools required I suspect I will have to: 1. Drain the coolant from the bike 2. Remove the seat and possibly the fuel tank if I don't have access 3. Replace the valve + hose 4. Reconnect fuel tank and replace seat 5. Refill coolant 6. Leave it running to run the coolant through the engine and test for leaks Am I in over my head or does this sound simple enough? I've pulled bikes apart before but I'm an amateur by the best measure and am happy to pass on a job that is outside my limits.
