Well I got the coil kit installed when I got home last night. Overall, it's a very well made unit and the instructions that came with it were easy to follow. The total installation took about 15 minutes including the time I took to remove and replace the right side panel for easier access.
I haven't had a chance to ride it other than down the street as we have rain here this weekend. I also rode it down my driveway and around my backyard. Overall, it seems to idle even more smoothly now. I did notice that now that I have it on, if I just give a little juice off the start, the wheeler dies like it used to before I added a fuel controller. I know, don't throttle like a girl and it won't be an issue. Anyway, my guess is hotter spark, burning more fuel so it needs more fuel at idle. I'm gonna bump my fuel controller up a half bump and see how it does.
My initial thought is that this item will compliment the CDI box nicely as both of these products have made the Grizz700 just feel smoother all around. It's near impossible to describe the difference in the feeling of smoothness that I'm trying to describe, but acceleration, idle, just the vibration of the motor is more crisp and SMOOTHER. Something you can't understand until you add these items and go, OHHHHH, now I see.
Let me see if I help you understood smoothness as I'm referring to it. Take 2 cars, a brand new corvette, which has a lot of power, is fuel injected and when you get on the gas, you receive that power and feel it beneath you in a real smooth and crisp power band. Folllowing me? Now, take an old Corvette with a carbureted big block. Again, a lot of power and more so than the new injected Vette. SO, in the old collector car, you roll into the gas and again, you can feel the power, but it's different. It's more of a vibratory, rough feeling power than driving the new one. I know, it's not really the same but it's the best I can do to help you understand until you just get off the coin and go buy one for yourself.
Anyway, I hope that helps to give you a feel for how the CDI box along with the Coil kit have helped the feel and crispness of power on the Grizlly 700. Personally, I'm very impressed with the change they've made.
