Quite a few people have been asking about in-line Bultaco Betor forks and I have finally had a look in the fork buckets tonight.
There is only one pair of in-line 35mm Bultaco Betors and they are the type that use a taper fit into the top triple which to me means Pursang M11, Mk2, Mk3, Mk4 or Mk5. There is a brake torque arm lug only on the brake side slider and both sliders have a single axle clamp bolt.
I don't have any Pursang triples to suit the taper top forks.
One slider has taken a minor hit where the seal sits. The other fork leg is fine. The side with the damage has been disassembled so if someone wants them I'm willing to pull the complete leg apart and make sure there is two complete sets of correct internals. The damaged section could probably be used after being panel beaten back round, but to look perfect again would require welding and machining.
Both tubes have minor pitting where the seals run, and no knurled section. I do have other tubes with the taper top, but they all have a knurled section to suit the lower clamp on some other model so would probably look out of place on an early Pursang.
Regards
David
