I hoping some 450RL owners can chime in and say if I should just avoid this bike. These bikes are rare where I live so there aren't many. I went to see this one and the condition was bad but I'm wondering if it's saveable and worth considering if I get a good price?

Main concerns

1. Scratching to the engine case around the sprocket, I don't know if it's still an active issue. The chain is a DID 520 V0.
2. Possible leak around the sprocket, the owner said it's just lube and dirt but I'm concerned it's leaking oil around the front sprocket
3. The owner (2nd) did no maintenance and you can see the mass of oil in the crankcase breather which I find concerning. The odo is 8000km and he said he owned it for 3 months and put on 2000km.
4. I'm curious what causes these slices on the edge of the rear tire?
5. When test riding I one time it flamed out with a rather large bang, is this normal?
6. The neutral light was showing in 1st and second gear sometimes and it wouldn't go into neutral when stationary.

The original wheel-set and parts are included but I feel like I already know the answer to my question after writing this out. I'm just wondering if it's still saveable and worth a shot if I can get a good deal. It's just sad to see such a bike neglected and rotted.
