I will not take this space to complain about how the japanese motorcycle manufacturers used screws that were made out of butter on 70's and 80's bikes, I will use it to sing the praises of Dynojet, because they make a fantastic product. I've heard horror stories of plug chops and air correctors and weekends of trial and error to get "close" to perfect. With the Dynojet kit, based on my bikes current modifications, I was able to do all that trial and error in one shot.
My bike has improved throttle response, increased power and oh my God that sound. I DO still have a bit of fine tuning to do, but I believe it could be ridden indefinitely as it currently sits.
The one thing I would suggest, is that if you have access to one, use a drill press and some type of jig to bore out the slide lift holes as per the instructions. Doing so by hand is possible, and it's what I had to do, but you could ensure a nice, even bore with a drill press.
The kit is a bit spendy, but it saves you so much in time and frustration that it is still worth the four stars, and I will buy another one when needed.
