Steve, great to find out the problem and fix it.
The reason for 2 springs, not helper springs, is safety. If one breaks,
and it is WOT, then you get the picture. All racing organizations
require them for good reasons.
I think that all Tigers feel better if they are messaged, including
throttle cable, or whatever.
Mine must be Really happy, as it has been messaged a lot.
