I found a yz450f for $3,700 that's not to far away from me, any opinions on if it's a good bike, anything I should look at? He started the bike with a single kick on a cold engine... My last bike which I sold 5 ish years ago was a yz400f which was usually 10-20 minutes of hard kicking getting it running. The owner is the second owner, plastic isn't great due to being a trail bike the last year or so and has the normal wear marks. Previous owner put new bars, grips and also did engine work. Head work, cams exh and I am not sure what else. The present owner said he could get me the list of what was done if I want it. Any opinions on if the price is ok and and thing else I should look at?
