[QUOTE="Road_Runner, post: 1430066, member: 28288"] Coolant is a bit slippery, but not nearly as much as oil. Coolant comes in two flavors... red and green. Very thin red fluid would most likely be coolant. It is certainly possible that your radiator cap vented coolant down the overflow tube. This might mean a bad cap, or overheating. Unlikely it is fork oil... usually forks weep not blast out oil, and if they did you would know as you would have oil all over the lower fork tubes and brakes. As for the statement about the switch to synthetic not being the issue, synthetic oil is really not all that much different from conventional oil. It is true that early synthetics did in fact cause leaks due to early chemicals used in the manufacturing process eating away at seals in the engine, but this is way in the past. Here is some good reading on the subject: [URL="https://auto.howstuffworks.com/switch-to-synthetic-oil.htm"]https://auto.howstuffworks.com/switch-to-synthetic-oil.htm[/URL] If it were in fact an engine oil puddle, my first thought, and it seems others first thought also would be the oil filter. Not lubing the oil filter gasket or it is loose..... [/QUOTE]
