Pulling the rear wheel forward used to be a MX tuner tip to get the wr400/426 to turn better.
At the time I had ditched the hohum stock chain guides for the zip ty teflon ones which have their own issues but you don't have to worry about sawing on aluminum with your chain.
Anyways, I am not answering your question as succinctly as Terry, but you might like the effect of having the wheel forward, in which case I might try aftermarket chain guides or clearancing the stock units for your application.
