so when i received the bike i quickly went out to get the replacement oil, and having a rather limited selection locally, I went with Castrol 4T for no other reason than it was motorcycle rated, and that Castrol GTX has been treating my car well for the last 17 years.

At first i found rather hard shifting, but after 100 miles or so i found it worked out so well that not only could i find neutral when stopped, but i actually could float shift!! Not that i normally would do that, but its possibility I believe indicates an optimal transmission.
But unfortunatly at 5.99 + tax, i didn't plan to stay with the 4T...

So I found Castrol had another motorcycle oil thats was 'supposed' take into account higher temps, high revving ATV and off road engines. Sounded appropriate for our bikes, and i could buy in bulk on line.
And since it had the same specs as the 4T, thought id give it a go.

Only it is also showing hard shifting at first, I really hope it smooths out as the previous did cuz i likely have enough oil for the life of the bike...

So, my quesiton for you all, do you guys also find a breaking period after an oil change??
And who else has found the ability to float shift, and what oil did you use?
