I am switching over from a Suzuki DR350 to an '06 WR450 When the going gets tough, that DR is unbelievable....like a billy goat. I think its virtue is that you can lug that engine down to like 100 rpm in a tight section almost like a trials bike. You can almost count each firing of the cylinder !! The new WR is nice, but once you drop below a certain rpm (I don't have a tach), it can rather abruptly stall. I can slip the clutch and do other things, but when the going gets tight, it is just one more thing you have to be aware of = harder to ride. Is there an easy (cheap) way to fix this problem aside from maybe a heavier flywheel?
