* Oil and water do mix !

Got some pics here to show emulsified oil and water inside an engine .
I installed this SE hyd. cam plate 1000 miles ago and the owner brought the bike back complaining that the cams sounded noisy . They sounded noisy to me to so I opened it up to see what was what . The hyd. tensioners don't work well with this stuff in there ! After finding this I got the owner to my shop to show him . Turns out he's just doing short 10 minute trips back and forth to work ! ...

Interesting... I knew it wasn't good to just let em run in the driveway for a bit then put it back in the garage, like the boys up North might do over the winter.

Schmidtys, I am sure there is not an exact answer, but what would it take to prevent this? I assume engine at operating temps, but for what duration? And under load I would assume.

Nasty !.....And THAT is the reason i don't and can't ride to work.

From my door to my office is 12 mins.MAX..

I drop my oil before storage,add a spash of Stabil hook on the Tender and forget about it till spring. Never did get why people would start it up for nothin..

Would ya do a couple of short oil changes on that to flush'r good Schmidty ?

I discussed ways to avoid the accumulation of condensation with the owner yesterday . Obviously getting the engine and crankcase up to operating temp. would be the ideal solution . TC operating temp is 250* . It takes forever to get the crankcase to 250* .
The owner is aware of the problem now so intends to get the engine warmer before shutting it down . I'm also going to switch the bike over to Syn3 oil . The Syn3 won't emulsify with the water as easy as regular engine oil does .
The worst thing for the people that store their bikes in the winter is to start and run the engine every now and then because the engine won't get warm enough to burn the condensation off and blow it out the breathers .

I'm gonna take everything apart to clean most of that crap out then change the oil over to Syn3 and then I'm gonna run the engine real hot while watching the temp with my Raytec . That's about all that can be done short of a complete engine disassembly !

What would happen if you gave it a quick flush of kerosene or diesel?
Had a boss once that did it to his truck engine and it ran good after, cleaned all the crap out.

Might I trouble you for the operating oil temp? As I have been riding in the colder temps, my oil temp dipstick reads 175* and never gets hotter.

Also, my trusted parts guy that has been riding for 35 years told me once to let the bike warm up until the rear head is hot to the touch before riding. Does that make any sense to you, Jedi Master?

Do you have an oil cooler?
