octane

Do most of you guys burn 87 or 91 or 93? Does it matter? Will any of them harm the bike somehow? Just wondering.

Also, how many miles do you put on the bike before its FIRST oil change? I'm still in the break in period. Wondering when I need change the oil for the first time. IN LUV WITH THIS BIKE!

I run 87. Run the lowest octane, then if you hear some pinging go up a grade.
Change the oil at 100, 500, then 1000, then I do mine between 2500 and 3000 from there on. Buy an oil plug with magnet tipped end also to catch any wayward stuff floating around in the sump. Take a look at Paulo's thread and see what his magnet end caught.

Previous ride was a 2007 KLR Black/Silver, I miss it..
Looking to get back into KLR's sometime soon.

I think around 6000 miles seems to be the mythical mileage for starting use of Synthetic.

My opinions.

Octane really doesn't matter until you get into high compression/advanced timing on highperformance stuff. I might use midrange in the hot summer.

Oil change - What I would do. Change oil and filter at first 500 miles. Then again at 1500 and at 2500/3000 intervals thereafter. I use Rotella 15/40 in the diesels and bikes and Castrol syn in the gas trucks and car.

I would not use the syn in the bike (or anything new) until after several thousand miles breakin.

I overmaintain everything. When I find something I like, I keep it. Oil is cheap.

Oil used to be cheap..... guess it still is compaired to a motor rebuild.

I am actually an engineer at an Oil refinery. This is a quote directly from the experts, "Many high-performance engines are designed to operate with a high maximum compression and thus demand high-octane premium gasoline. A common misconception is that power output or fuel mileage can be improved by burning higher octane fuel than a particular engine was designed for. The power output of an engine depends in part on the energy density of its fuel, but similar fuels with different octane ratings have similar density. Since switching to a higher octane fuel does not add any more hydrocarbon content or oxygen, the engine cannot produce more power."

Technically, this is a quote from Wikipedia, not directly from the experts, but the experts, Chemical process engineers, agree with this.
At the end of the day, do not use more expensive gasoline unless you need it.

Running high test in a KLR is like giving a wino Dom Perignon.

A higher octane gas is simply more resistant to predetonating (going bang before the sparkplug ignites the fuel). A higher compression motor builds up more heat which will ignite the fuel before the piston reaches TDC. The KLR is not a high compression motor.
