Hello all, Apologies as I have made my 2000 WR400 street legal without updates here (been waiting to end school) and have been riding highways and streets plenty with no apparent problems, mainly short trips. IN LOVE with the bike. I have been running controversial Shell Rotella T in it. I had been keeping an eye on this and it looked fine. A couple weeks go by and I don't check. I said "Hey after this ride this next weekend I'm gonna change it anyway,literally 4/25/14." I've put maybe 1000 miles on it since I first put the Shell in. So today I am going about 70 on the freeway and the rear wheel locks up. I nearly lost my life and several motorists must have had to check their pants as it was rush hour and they were tailgating me. I'd never been more scared, or lucky. The bike is fine and so am I, except for this. I got my WR to the side of the highway to check it. When I pull the clutch lever in, I can roll it. There is no neutral right now. If I try to move the kickstarter slowly, the bike WILL move forward. My friend and I were able to load it and get it home by holding clutch lever in. We put some oil in as it was bone dry. Again, the bike would move if I tried to use the kickstarter/decomp but I can't try to start it if it rolls off the kickstand. I'm afraid the engine is blown and I'll have to start over. Where do I begin to troubleshoot? I feel ridiculous even asking after my mistake. Thanks..
