I was slightly hit by a bicycle in a afternoon peak traffic hour. It was fine I didn't pay attention to my bike. In about 20 mins (I can't tell exact from now) I felt the engine making some different noise. She has oil cooler installed. I saw oil pipe was folded, and whole engine oil was leak out completely. no............ I immediatly shut the engine off. Dismounted myself stood still for a min or two, couldn't accept the nightmare as to any engines.

I pushed the bike search for a repair shop, luckily I was only 1 km away from one. Got the pipe repair and added 900ml engine oil. It started.

When I found out the leak out, it had been run for 20min or 10km proximately (ave rev range 3-4k, low thottle). Possible no more oil circle to cam (opened valve obeserv cap, light cooked smell), gear, clutch, piston. and the oil was pumped out to my right foott. But after added the oil back, rode for a few kilometer, I didn't feel much difference. The horsepower was till there.

Engine is Suzuki GS 125. My quenstion are:
1. What could be most possible wear, damaged? piston ring? cameshaft?
2. What should I look further?

cheers.
