I just bought an F3 about a month ago, first bike ever, super clean and I love it!! Anyway, the guy I bought it from threw in a new chain and sprocket that he didn't put on. So I rode around for a few weeks and decided to take the time and change it.... I took off the 43T sprocket it had on and put the 45T sprocket that he gave me. The bike feels like it lost alot of bottom end when I take off. Should I be feeling this or what??

If anything it should beel like you gained power not lost it.  Just be harder on the throttle.  It takes more revolutions now to go at a certain speed so you are going slower at a given throttle position however you have more torque.

I give it full throttle and it still feels different.... I would power wheelie 1st like nothing before... now I have to go to like 8,000rpms and let off and crack it to bring the front end up

You sure it wasnt the other way around?  you took the 45 off and put 43 on?

wat about the front sprocket? 1 up on the front and 2 up in the back would produce wat u r describing. also, if the rear wheel is now spaced farther back because of a longer chain, itll be harder to bring the front wheel up.
