Just had a new throttle cable installed in my 89 Westy.  I wouldn't think that a throttle cable would make much of a difference at all, but oh my, feels like I'm driving a new vehicle. The vehicle is so much more responsive, it's not even funny.  For anyone who has a vehicle with over 100,000 miles, this is an upgrade you will really appreciate.

Cheers,
