I've been enjoying all kinds of motorcycle racing and riding for a few decades now and have had a marvelous time doing. The last 6 years I've been enjoying riding motorcycles throughout rural Southeast Asia with an emphasis on as much off road as possible. Trips range from a few days up to a month long. I want light weight on my next bike. Th new KTM 500 is a nice package but its still 265 pounds ready to ride. I did some two and three day trips on my Yamaha YZF 250 and enjoyed it so much better riding technical off road. Primarily due to the weight only really missing the 525 on longer tarmac sections. I now have a KTM 250 XCF-W (w/300 cylinder) and I'm toying with the idea of running this on multi week trips. Here's my question: I can run synthetic oil in the crankcase when I leave on the trip but most places I'm heading only have conventional oil. Sooo all my oil changes will be done with conventional oil. The bike holding a hair over a quart will mean I'll be dropping oil every few days which is easy enough. My question is will a motor designed for synthetic be able to survive a few hundred hours running conventional oil for 70% of the time????? My thinking is my old 525 handled regular oil when forceed to with not much problem, however it only used it probably 20% of the time. How about some insight from the brethren?
