Welcome Lee Davis,</p>
Really don't know, for we own RTV 900.... </p>
For I haveheard of people doing different things to their machines to gain speed, not only the Kubota's, but other Utiltiy vehicles also, and when it comes down to it, the question is, is it worth all the effort and money / time, just to get two or three MPH more out of the machine. </p>
In some ways, it would be nice to go a little faster with the RTV's, but the way I look at it. Kubota has spent millions of $$$ on researce and design on building these units.Figure they are a little smarter than I on the pinging and panging on their machine., if I get to messing with the flow of things on the machine, not will I mess up the machine, but I will probobly mess up the RTV, void the warranty, and end up either purchasing another RTV, for I just screwed this one up for sure.... or just right out end up walking ~~~~</p>
Now I did notice one thing, when I installed the High Rise Intake, it made my machine run a little faster than it did when purchased, but the reason for the intake was not to increase speed, but to keep better / cleaner air going to the engine >>>></p>
Imagine it is some secret somewhere one can do to increase speed, but my suggestion would be, leave well enough alone and enjoy, you knew how fast it would run when you purchased the machine, that's just my 2-cents worth.....</p>
Do you like the power of the 500 ??? Never worked out of one .</p>
