Lots of good info on water logged bikes. Just remember to ground the sparkplug when turning over the engine to avoid destroying the CDI.

We did have to drain Waylon's carb, at least 3-4 times. And we basically "boiled" all the water out of the oil by letting the bike idle for 45 minutes or so with the oil filler (mounted in the frame on the DR) cap off. It was steaming like a teapot for a good 30 minutes until the dipstick went from milky white to just oil. Probably had a cup of water in the oil.

Oil burns off at 500+ degrees, water at 212. Typically fully warmed temps are way over 250 in the crank. That's why highway mileage is good for vehicles...getting them up to full operating temp for a longer period of time boils off the moisture that accumulates in the crank each time a hot motor is turned off and it draws a vacuum and pulls in wet air. That's why oil manufacturers argue to change your oil periodically, even without mileage, because the water breaks down the long chain molecules necessary to protect today's close tolerance engines.

You sure you don't work at an oil company?

Shadman is wise...and TP is wiser for posting them pics! One day I'll get into TP's stash of secret pics...

LOL, if only engineering looked this good in person I never would have changed majors out of ME after 3 years!
