I have a 01 450ES with 1100 miles on it. It runs fine, has plenty of power but when I get into 4th and 5th gear, it smokes pretty badly. White/Blue looking smoke. ?? Any ideas where I should start looking to remedy this??

Thanks for all help and advice!

first do a compression test. if not that your oil rings could be failing or your valve guides and valve seals could be bad. there are several thing that could cause it but hard the diagnose without looking into it.

this may sound dumb but check your air filter. i have seen cases where the air filter was dirty enough that at high rpms, the engine starts sucking oil passed your valve seals.

doesn't sound good - wonder why it only does it in higher gears? do you wind them out more than the lower gears when you ride? hopefully your air filter is dirty as shooterman suggested.
