That is nothing to worry about, it is not off by a whole tooth so there is nothing you can do about it.
Yeah the T mark and the sprockets all line up with old belts. I was very careful I kept checking the marks during installation to make sure nothing had moved. I put Napa #250274 (Gates) belts on and these are supposed to be the equivalent to OEM Honda belts for the 77GL1000. It was a little diffficult getting the left side belt on, it was like it was a hair to short. Maybe I need to try another belt. The belt will not go on with the marks dead on. The pulley has be out of line this amount for belt to mtn. on pulley. Here another pic. and again remember T mark and other pulley line up fine.
