Hi Mike,
Congrats. on your new baby.
The general wisdom about more oomph! is to put a free-flow manifold, twin
exhaust and SK Pancake Airfilters on.
You don't say which carb(s) you have, I have the standard (UK) twin HS4 set up
and am happy with the power they give, if you have a single stromberg or
something similar, consider the change (about 200 sterling for a pair of new
SUs), alternatively if you have the money, go for a pair of Webber 40s or 45s,
but initially I should try the exhaust/air-filter upgrades.
Get hold of a Triumph-Tune catalogue (available over here from MOSS) for the
real dirt on better performance.
just my 2p.
Happy upgrading,
Chris.
