I agree with everything except the oil in your transmission. I have been out of the tomos game for a bit, but I believe you want to only run an ATF in your tranny. They make some good racing ones for drag cars running automatic. I got one that is blue in color and definitely more viscous than the regular red ATF.
You also might not get the wheelies you want unless you change out he second gear spring to have it shift later. It will shift pretty early with a nice kit on there as it is all based on rpms. I know with my za50 I wasnt able to do wheelies until I flipped the second gear and caused the shift to happen later.
