8550, 8532, 9389 - SOLD EACH - Slide Springs ~ For PHF/PHM ~ Choose the right spring for your application....
Light = 0.7kg/70mm. Medium = 1.1kg/70mm. Heavy = 1.4kg/70mm.
If you wonder what size you currently have, use this info to tell >> .7 kg springs = 1mm dia = 127mm length = 17 coils >> 1.1 kg springs = 1.1mm dia = 132mm length = 17 coils >> 1.4 kg springs = 1.1mm dia = 135mm length = 15 coils
~ Please remember that if you are trying to get a softer throttle, just going to the lightest springs might get you what you want, but I would be VERY careful to make sure your slides stay absolutely clean. Any dirt gets in there and that light spring might not be able to push it down, and if that happens your engine won't shut down. Bad news if you are coming in to a corner too hot already.
