HiAnyone fitted a lighter return spring. After ten minutes my wrist aches...(lol).I'm sure the one that's on there could close my garage door.Any lighter ones that you guys might recommend pleaseSent from my iPad using Tapatalk
It's there, not ro return the throttle, but to strengthen your wrist.
Enlarging the picture, it does look like a quick action throttle, had one on a 400/4 around 30 years ago, bloody heavy action, resulting in some very dodgy behaviour on wet roads. That is almost certainly the cause of your problem, only real solution is to get shot of it!
Where's your pod filters?
