HEy update on the Dt1 trackmaster. Had a big chat with the man and he told me she was one of the first twin shock frames they put together for the YAms, these original dt1 frames were made out of triumph tubes, and that explains the xtra head room,
the first one was made out of "scrap" bends ,spliced together. the first unit Neil built now belongs to bill milburn ,his long time friend and
historian/collecter.
"our basic geometry was based on triumphs"
the first few tube frames that got going had blank headsets, they made up a few until they got some track time and feedback that they actually worked fine on the track. later they jigged up from them to get some production going to meet what they hoped would be a 2 stroke revolution in the sport and pay some bills. ( smart boys)
So i guess i finally got my answer as to why mine has all that headroom and no stamps. Bit of a find really. Neil said he is interested in me putting it back to original and if anyone saw it in the pits its got a diamond glass tank and the long set set from the later models in a period marroon, he's promised to send an original tank ( i think they were tear drop) and a solo seat and pillion ( not convienced about that myself yet) and should probally get it painted up in the same ascot colours he used in 69 but im not so sure of the dodgey number 10 he was famous for, specially with the hand painted numbers id feel like part of the "Goodies" show:O)
History is a wonderful thing when you find it, and i was thinking bout a pre 70 unit anyway so it mayas well be this one :O)
pps - back on the exhaust thread check out the one on this bike ? fat enough ? what he told me he did was recut these new expansion chambers off Motor crossers that seemd to work a treat and just realigned the cone and neck lenghths and shaped the power range from there to get the torgue in the right place for the track/motor, they previously did the same thing on the bultaco he built out of lunds shop.
