I have -1 +2 and I was wondering what if I went +5 on the back and back to stock on the front would the rpm stay the same or be alittle lower?????

-1 at the front is approximately the same as +3 at the rear.

My webpage above will show you more info (thank to BarMatt for posting it).

I know about the -1 +3 I was wondering if the rpm is the same or better to leave the front at 15 and go bigger on the back

The smaller the front sprocket, the lower the life expectancy for the chain & the sprocket (because as the chain turns the tighter circle it builds more heat, which is the primary cause of seal failure, and in turn leads to chain stretching & wear). Thus, going up in the back is always better than going down in the front...

As for the RPM's, see the tables on the webpage listed above.
