: Scott no doubt about it, they are
: slick!
: What can sometimes be literally hours
: of futzing around (with an out of spec
: gear) is reduced to a simple
: adjustment, it's kinda
: anticlamactic....
: The rotating weight penalty is
: certainly small & the $$ cost is
: what it is.
: Now... what would be really trick would
: be a gilmer belt drive setup like the
: BMC A-series conversions...!

: for installation over the weekend.
: I'll let you know how it works out.
: Just seemed to me that it is going to
: be much easier and more precise. We'll
: see.

: That's exactly why I have never seen
: these as a must-have, that plus the
: anal compulsions I have about excess
: weight & spending $$.... but...
: I have found that some of the
: replacement gears aren't offset as are
: the originals. At that point the
: options are an adjustable gear... or
: the obvious...
: Glen
: with slightly retarded timing

: I question the need for one of these:-
: You can't adjust them without
: dismantling the front of the engine -
: unless you make a removeable plate for
: the front of the timing cover.
: Triumph designed the standard sprocket
: to allow fine adjustment, by bolt holes
: offset from the tooth centres. The
: wheel has 42 teeth, so that's one tooth
: per 4.29 degrees of crankshaft turn -
: call it four and a quarter. Then,
: rotating it 90 degrees on the camshaft
: allows it to be changed by half a tooth
: - 2.125 degrees. Then turn it
: back-to-front and bolt back in the same
: position for a quarter tooth change -
: one degree and a fraction far too small
: to be useful.
: What more do you want?

: Scott I think Ken Gillanders sells

: recently put one in his 6 cylinder, I
: can't remember the supplier.

: Can anyone recommend a source for an
: adjustable cam sprocket for the GT6 - I
: would think it would fit any Triumph
: equipped with a dual row chain - TR6,
: GT6 or Spit.
