I just purchased a vortex sprocket set and a new did chain and this is my first new install. I know about how to take everything off and all that my only question is do i need to push the rear tire to the front or align with the marks on the swingarm or pull the rear tire to the back as of the swingarm as I can. Second how to you measure chain slack.

to determine how many links you're going to cut off, push the tire as far forward as you can.

after installing the master link, align the rear wheel by using the notches by the axle. measure your slack using the bottom run of the chain. with your finger, push the chain up and down along the part where it gives the most slack. the total movement from pushing up and down should be an inch, + or - an eighth of an inch. Keep in mind that sometimes tightening the axle, once your done adjusting the chain, may affect the chain tightness, so check it again after you have everything tightened up and make adjustments if you have to.

There are vids on youtube on how to adjust a motorcycle chain to help you.

align the rear wheel by using the notches by the axle.
There is some play in those brackets. In my case, the wheel alignment isn't very good when only going by those marks. I've been using the string method to align the rear wheel. (Might try switching from using string to using something solid like conduit.)

I have also never had an issue with the notches, they seem to get the job done pretty well. Of course one of these ^^^^ chain tools is very good to have around, and they are pretty cheap (I still need to pick one up).

Are you only going by chain alignment and/or notch alignment, or do you also check the actual wheel alignment? The wheel alignment method could be off due to distortions in the tire(s), but the other methods could be off due to the frame or play in the wheel alignment brackets.

Imagine that both alignment brackets have a certain amount of play, which they do. Then imagine that they slide to opposite extremes. That's assuming the adjustment bolts and end caps are seated properly. It doesn't sound like much, and maybe it isn't, but I think my alignment brackets are inaccurate enough to ignore them. Not 100% sure. Maybe I'll take some photos and see what there is to see.
