Every time I ride, I get this burning smell coming from my bike.
Any thoughts?

Blown or leaking crank case seal causing the oil 2 mix with the fuel and ultimately make your beautiful bike smoke and smell rather foul!!!!

Re: Burning Smell
Check the valve guides. If these are worn, oil can run down the valve stem onto the crown of the piston. The oil is then burnt in the cylinder causing the bike to smoke.
The Ford Pinto engine was prone to this as were many early engines that overheated regularly causing the guides to crack or wear rapidly. If this problem persists you might want to consider changing the engine for a more modern water cooled one.
Always happy to advise

Re: Burning Smell
That poor young lady she seems to have had her Jeans ripped off completely in the accident. Can't say I'd advise riding without knee protection. In fact it would seem after a closer look she's not using any protection at all, not something we TRFers would recommend at all. You won't catch any of us with our trousers down.
