    I suggest you read the stickies on top of the 2 stroke section. Sorry, but it's already been discussed a thousand times

    Welcome to the forum.

    Getting to 70 mph on a GP1200R is not uncommon, where as 75 is going to take some serious work and a little bit of money. You will find that there is no silver bullet to getting there, unless you are just willing to fork out some serious $$$$$ just to get there in a hurry. It does involve a few bolt on performance parts, and the removal of some of your stock components. Fortunately for you, this hull and engine has been developed. In other words, there are not to many surprises. Also, many of the components that you will need are being sold on this forum used and in great shape.

    May I suggest to you that you do some research in some of the stickies above, especially the ones that discuss "speed tricks and performance gains". The best path for you to follow if you have a completely stock GPR is to focus exclusively on [B]hull,transom, and shoe [B] modifications. It will require certain bolt on pieces like a modified aftermarket ride plate and intake grate. In this way, you can document the improvements easily. You will need a GPS and an aftermarket tachometer to be accurate, because certain modifications may make the boat handle much better, yet they will slow you down. These meters will help you to keep track of things so you can see and feel the improvements.

    Your boat probably is running 61-63 in a best case scenario right now if it is stock. With hull (and pump) mods you might get it to about 66-67. You will find that for every 5 mph gain that you achieve, you boats handling characteristics will change.... mostly to the good. However, some of these changes are dangerous.

    Do a lot of reading, and get a tach and GPS to first figure out your starting point.
