I purchased the gp3-30 for use on my 2007 Yamaha Vmax. The no loss chuck on the flex line made it very easy to get the correct pressure in each fork. Well worth the small price for the piece of mind knowing the front forks are both adjusted to the same level.
Super sweet little pump. I purchased the 100psi rated one. Very well packaged and seems to be very well designed and made. After recieving from Dennis Kirk at lightning speed< I removed from the plastic sleeve and left it in the sponge packing designed to fit perfectly so it wont get damaged in the saddlebag>alot better made and designed than the Harley brand!
For anyone with a touring model Harley Davidson with air shocks, this is a necessary piece of equipment. Using an air compressor to fill shocks can easily rupture the low pressure airlines. Additionally, this unit is compact enough, it can easily be packed along for the trip. It is easy to operate and most of all, accurate.
Tried out the pump on my 1500 Nomad and it worked great. The zero loss feature works as promised. Easy to pump up the shocks and the bleed valve allowed me to get the pressure easily within a psi of what I wanted.
My main reason for buying the pump / guage combo was to adjust air assisted shocks. It does everything the ad says. Screws on and off without loss of air, Pump works great for small volume air needs such as cycle shocks and forks. The air release button allows easy adjustment of pressure if less is desired. Very good quality product that I would definately recommend to others.
This is the best pump for my limited airshocks I have purchased, I purchased two other different brands and they were junk fell apart after one or two uses, this one is heavy duty and works great. Do not use an air compressor to pump up your shocks!
