[QUOTE="Ol'89r, post: 720296, member: 17212"] xr284. Have you checked your pick-up or source coil. I have seen these go bad on XR's before and they act much the same way as you describe. Bike runs fine until it heats up then starts to miss. Have also seen one come loose inside the case and the bike acted the same way. Missed on top end, ran fine down low. Remove it from the case and do a visual inspection. Check for cracks or indication of heat on the insulation. Then check it with an ohm meter. Note, these can check good with an ohm meter and still go bad when they heat up. On electrical problems the first thing to check is the wire connections. Unplug and inspect for corrosion each and every electrical connection. Before you plug everything back together, go to your local auto parts store and pick up a tube of dilectric grease. Put a small dab of dilectric grease on each connection. This will eliminate corrostion. Side note. A broken or weak valve spring can also cause a top end miss. Just my $ .02. Hope it helps. :thumb: [/QUOTE]
