Hello, Long time follower, but I haven't posted a lot on the forum. Thanks in advance for all the help. I'm the owner of an 1989 XR600R, which I dual sported for about four or five months back. I've ridden about 1,000 miles on the bike with the normal updates/upgrades (ie Ricky Stator 200w stator and XR's Only Choke Plate) This past weekend, I went for my first ride on the sand dunes in Florence, OR. The bike didn't skip the beat the entire day but ran into a problem literally a mile away from the car after 4-5 hours of riding. The bike suddenly died (not sure if I lugged down the engine or not) and wouldn't restart. I managed to get it bump started in third gear after being towed for 500 yards and rode back to the truck. Since then, I can't seem to get it to fire at all. I noticed some sand had managed to get past the edges of my air filter and was stuck to the outside of my choke plate inside the carb. Is it possible sand got into my engine and caused it to not run? What kind of damage would that do? I checked both jets in the carb and seem to be clear. I did notice the compression seems to be low (I don't have a compression tester). I can cycle the piston all the way through without using the compression release, which I never had been able to before. Is it possible the rings are worn and the lack of compression isn't allowing a good vacuum for the fuel to be drawn to the cylinder? Thank you and please let me know if there's any other information I can provide to help dissect the issue.
