Now that I have a 69 DT1 and a 70 DTI-CM thinking of adding a 1968 DT1. My question is it worth searching for the bike and correct parts? About 10 years ago I restored a 1969 CB750 to 100 point restoration. It was a pain to get it right and lot's $$$$. Are the small bits and pieces impossible to find? Are the bikes just too expensive to purchase and restore correctly? 

Like your Honda the '68 DT1 is a tough one to get right with all the unique parts plus low production number of 15,000 for the US market and 5,000 for the rest of the world. Better to find one already done and pay the a$king price. It will be easier and cheaper that way. I know from experience. I have 2 '68 DT1, a '73 RT3 and a '71 RT1-B restored by others. All 4 are museum quality. I don't regret paying the a$king prices. I don't think I could have done them as good, especially the '68 with the curved exhaust stinger, 4 o'clock pinch bolt kick start lever, round button tool compartment, carb top side idle adjustment, etc...

Thanks for the info! I'm excited about getting back into Yamaha Enduros and maybe going overboard. Now you got me thinking about my DT1 and DT1-CM as opposed to restoring just make them look much better and ride them. I know once restored they really become garage queens and value is hurt when rode and scratched. 

I enjoy refurbishing them to the best of my ability while staying within my means (skill level and financial) and then ride them as time allows.
I soon will have more time (retiring end of year) but less money….
