Re: Pipes

[Eric Sheley <eric@xxxxxxxxxx>]

Ross,

Welcome aboard and thank you for your comments on the pipe and EFI. It is
great knowing that our comments on the bikes will be heard by Triumph and
possibly our criticisms or ideas might be used to further refine what is
already a run-away hit. I think our biggest desire right now is *build them
faster*! ;-)

I would like to second your request to the listers that your email not
become a direct pipe for every complaint or question on every problem that
happens to occur. I know that Triumph representatives subscribe to a number
of Triumph lists, but very few ever make any posts for fear that their
email might be abused. If we are having a common problem (like the fuel
gauges), rest assured that Ross will be able to see the pattern.

So to all the ST Listers out there, if you have a question for Mr Clifford,
please post it to the list and I'm sure he will answer if it is something
he can comment on. If you are having a problem, your first contact should
be your dealer and then your area Triumph Rep and then (for U.S. listers)
US headquarters in Peachtree City (Atlanta). 

Currently the list subscribers are pretty evenly split between owners and
non-owners of ST's. Of the non-owners, a large percentage are persons
seriously considering the ST as a future purchase. Largest subscriber base
is the U.S. followed *very* closely by Australia, then the UK, and then
Europe and Canada.

Again Ross, Thanks for posting
