EZ-Pull Springs

I went ahead and installed the EZ-Pull throttle springs. I simply loosened the hose clamps on each side of the carbs so I could easily rotate them since the springs are on the backside between the carbs and the engine block..I now found another area that really needs cleaning. In the photo, the original, factory spring is on the left and the new one is on the right. The wire gauge is lighter even if it is a bit longer on the EZ-Pull spring so I can easily believe their claim of 30% lighter pull. After snapping them in, you can easily notice the difference on the throttle. These old Beemers have a "maintenance screw" to add friction to the throttle tube to allow you to have a fast idle to balance the carbs. I had the screw turned down a few turns to help hold the throttle a bit so you weren't always working against the springs. I had to completely relieve the friction in order for the throttle to return to an idle. They are definitely much lighter pull. I then tightened the hose clamps on the carbs and moved up to the take a look at the throttle. There is a little gearbox on the throttle to turn the rotational force into a linear force and this is another area that is usually ignored during normal maintenance. I pulled off the cover and was very happy to see plenty of clean grease and the gears are in great shape. I suspected as much since the throttle is very smooth but it never hurts to check.

I took it for a short ride, partly to see how the throttle feels and partly to help charge the battery. I had left the key switch on Thursday evening which leaves the parking lights on so the battery was almost dead yesterday morning when I was getting ready to leave. I had it plugged into the battery tender all day but it wasn't enough to fully charge the battery. Tomorrow, our church is having another ride supposedly out to Rika's Roadhouse near Delta. I suspect it may depend on the weather as some of the riders don't really care to ride far in the rain. I'm not complaining about the rain since it can only help with all of the fires in the area. Hopefully, my right hand will like the lighter throttle springs...
