Hello everyone, first time posting, long time reading this group. I have had my RTV 900 for over 2 months now and I love it. It is strong, hauls plenty and tows great. I have the worksite model, with ATV type tires. I alsohave the plastic roof and the high mount air cleaner kit. I have had no problems with the machine and it will go just about anywhere, the "I shouldn't be driving that way" feeling will kick in well before your past what the machine can actually traverse. The fuel usage is as good as others report on this board, with mydealer fill lasting well over 20 hours to merely get down to a quarter on the gage. Great site here with lots of information that led me to purchase the machine.</P>
I'd like to share a little mod I have done to the high mount air filter. I had two issuses with mine, the first was the noise. I soon discovered that there wasnt a gasket between the two halves of the housing that come apart to change the filters. This was allowing a large ammount of air through the little gaps around the housing where the clips fit into and was really making some annoying wistling noises. Did your kit have a gasket in this location? I fixed mine with some silicone gasket maker.</P>
The second issue was the air inlet that was basically wide open facing down. Occasionally we have some relatives kids tag along as we ride the fences or look at the cows, and they were allways wanting to put thier hands over the intake or put something in it. Before the gasket mod, you could block the downward inlet and it would take in so much air around the housing the engine was not effected and really it didnt pull enough vacuum to hurt. With the gasket it maybe a problem and could hurt, I wasnt goin to try it. </P>
I got to looking around and fabricated a new intake that was raised up higher and was large enough that no set of hands could make enough of a seal to get hurt. I used the upset end of a 2" PVC pipe, some hose clamps, the "mushroom" intake cap from a JD 4240 tractor,some black paint, and part of an old rag. The old rag was used to increase the thickness of the PVC slightly to acheive a tight fit of the intake cap. I also slit the small end of the PVC fitting so the clamp would be able to squeeze it down to the filter housing. The filter housing was rotated so the inlet pointed up and the end cap was removed and replaced with the valve pointing down again. It also had the added benifit of further reducing the noise from the intake. It is nearly as quiet as it was before I installed the high mount kit, and actually has a little mean growl to it now instead of just a whooshing sound. I think it looks good too. I will attempt to attach a picture:</P>
