Hi. im looking at buying at 1999 yz400, it has old gas in it and possibly needs a carb rebuild and maybe valves adjusted. Is there anything i should look at specifically.How do these bikes compare to the 426/450's? Would it be a decent trail bike?
My first MX 4-stroke was a '99 yz400. Great Bike, very reliable.
They are a little heavier and a little slower than 426/450's. Still very capable bikes though.
That said, I don't think it would make very good trail bike; it's specifically designed for MX - the motor hits hard, it's geared tall, and suspension is stiff.
If your trails are not too tight it should work . . .
