I just picked up a 2005 WR450F that has mostly sat for the last five years. The carb needed a good cleaning but it runs good. It is on it's first replacement tire in the back and it is very new looking. It only was ridden during it's first two years and it is on original everything except the back tire. Here is what's going on... Fire it up, let it warm up. Go for a ride. The clutch engages like normal from a cold start and take off. After you are moving and get ready to shift into second, it's got a ton of drag, to the point where if you pull it in, it still will move the bike. It eventually will break free if you come to a stop with the brakes and the clutch pulled in. Then it's the same thing all over once you get going again. It's pretty hard to shift as you would expect because of the drag. It just doesnt seem like it has enough hours to have a worn basket yet. Could this be lack of oil on the plates from sitting? I have ridden it maybe 2 miles since it's been brought back to life. I have also tried adjusting the clutch even further out than I normally would to try to get it to disengage further. No change, other than a very late engagement at take off..... Any ideas? I have tried a search, but has anyone had something like this? I know some cold drag is normal, but this is not normal.
