Hey Vishnu, yea the kit was great. I had to do a few things to make it all work perfectly, but altogether it was a great kit. Thanks for the kit. Anyway, to answer your questions. I needed to buy the speedo back cover and 3 tapping screws from yamaha. The speedo mounting bracket I had to cut like this.
The bottom of the speedo cover I also had to cut because the metal for the windshield stay kind of got in the way of the cover as well. So if you can make the windshield stay detachable from the main headlight stay, then that would be great. If that's too much work, just tell them to cut the speedo cover just enough to get it on. You don't have to cut too much off the speedo cover, but just enough. Also this only applies to the rectangular speedometers.
Hope that helps.
