[QUOTE="Buckholz, post: 27018, member: 17671"] Ah, just found the article. Title "How to (not) sieze your new bike" 1999 Vol2, by Mike Rosso, KTM USA Tech Mgr Before your even kick your new bike over, change jetting to match your area. KTM's come jetted for 1500 ft elevation and 70F. (Buckholz note - Newer >99 KTM's come with an jetting chart in the back of the orange book, it works really well for me, as an aggressive A rider. I live at 7,000' but ride 5,000' higher or lower on any given weekend. The one mod I have made to jetting is to lower my float level/fuel height by about 3 mm) 1. Make sure your oir filter is oiled and properly installed. 2. Never assume the fluids are all there. 3. Always use the motorcycle manufacturer's recommended oil ratio when mixing your fuel. (Buck note - use premium fuel, mix in a steel gas can, use a premium "power valve" premix, pitch it, or burn it in the lawnmower when it is approaching 1 month old as the lube properties are going bad.) 4. Double check your jetting. 5. Warm it up. ....Do not rev it "to clean it out!" Just let it run at a moderate rpm until you can grab the bottom of the radiator and feel it warming up.... 6. Vary your engine speed during the first ride. It's best to do the break-in ride in a familiar place, where you can ride without a lot of hesitation or closed-throttle coasting. You want to ride at a moderate speed, be able to use all the gears, and be in a place where you're not afraid to use the throttle. The best would be a well-known hare scrambles course or open woods loop, where you can short shift and ride it at about three-quarters of your racing pace. Don't be afraid to rev the engine out, but don't scream it; and avoid "lugging" the engine up hills or in tight stuff. Coasting down roads or downhills with the throttle closed should be avoided. A closed throttle is the number one cause of piston seizures. Your break-in ride should be nothing more than an easy trailride at a moderate pace. There's no need to stop and let the engine cool, then ride some more, stop and let it cool.....one good, long moderate ride, using a whole tank of fuel should be enough to seat everything in your engine. 7. Avoid crunching your bike into gear. ...pull the clutch in during warmup, blip the throttle a few times, then let it throttle down before clicking it into gear, this breaks the clutch plate stiction, minimizing the "crunch" when you first put it into gear. 8. Change the oil. ...your tranny and clutch will last the longest and work the best if you change your oil after every ride.... Buckholz note - My two cents on tranny oil for a two stroke as a fatboy A enduro racer. Use one of the all purpose diesel oils (15W-40) and change the oil every ride (>50 miles). The diesel oils, Shell Rotella, Delo 400, Walmart universal, have lots of dispersants, are about the right weight ~85w gear, and are relatively cheap around $1.25 to $1.50 per quart. I buy in 1 to 2 gallon jugs. ------------------ [This message has been edited by Buckholz (edited 04-22-2001).] [This message has been edited by Buckholz (edited 04-22-2001).] [/QUOTE]
