Thanks for the info.
I also read DEET'S guide and have done more research on this topic.
Google- motorcycle wheel building. WOWOW!!!
I didn't even perform the basic steps to properly lacing up a new set of spokes... Will backtrack and do as suggested.
Futher inspection of my wheel build shows that the hub is definately, NOT CENTERED PROPERLY.
I also looked up part numbers for the 74 DT250A & 77 DT250D
the part sizes are as follows and numbers are dif because of alum verses steel so the prt numbers are not mentioned here.
74 DT250A front 1.60Ax21 non-con, st'l rim
77DT250D front 1.60x21con, alum rim
74 DT250A rear 1.85Bx18 con, st'l rim
77 DT250D rear 1.85x18 con, alum rim
The angles of the nuts look ok as they appear in the're loose state, but after doing a better preliminary set-up (lacing) I will look at the fit and angle again. I would really like to use this upgrade if possible.
I should also mention that I re-used the washers that fit between the rim and spoke nut underside, these were not used for the original steel rims that were on this bike.
More to come, later....

I made an error in this post, the rear NOS spoke set for the steel rim & hub did com with new washers. (connical hub & four spoke lengths)
Since the front steel rim is, non-connical/equal & only two spoke lengths, the washers were not present with that NOS spoke set. Not sure why this is but I will learn.

I would also like to thank those who chimed in with info & caused me to re-evaluate what I'm attempting to do.

OK Enduro fans, I've finally was able today to dig into what I would like to be my re-built front wheel assembly.
The results are not shocking, they only prove as mentioned prior, that a conical style rim should not be assembled to a non-con hub.
So I will have to buy new ones or refinish the orig. for my build to be safe. The search is on.
But first the result of my test.
I first identified the spokes to be used for centering the hub using painters tape and a numbering system, 1 thru 6, (3 spokes each side).
Then I loosened all the rest so they wouldn't be a factor.
I then counted threads on the spokes to tighten and also measured with a metric scale to be closer. Thread length left exposed on hub side of rim(approx. 3mm).I then turned each set 1 full turn and measured again with steel rule. After that 1/2 turn each till they started to tighten up, measuring length of exposed threads as I went. It did not take very long to see that a bind was occuring in 3 of the spokes. I don't believe this to be a safe situation. I would think they should stay straight thru the complete tightening process. Please chime in if I'm wrong as I have not done this type of build ever.

Well I have new rims in process with Buchanan spoke&rim, so I have a little time to rebuild the brake plates and have accomplished that today. Yay2
New shoes for both front&rear, a new grease fitting for the rear, replaced the worn washer set in the front that drives the speedo, a new outside seal on the rear, both plates also got new plugs for the brake inspection holes, added the re-chromed levers and looks like there ready for install when the time comes.
Hope everyone is having a good holiday. :) B)
