Here are the problems you can expect, beating on RTVs like I do: You'll buy lots of fuel, oil, Super UDT and filters. And some tires.
Yup. That's it. Well, not quite "it". I have had one oil cooler hose leak and one temp gauge go bad. And a wiper fell off. That's really all.
I follow the service intervals in the factory manual, except only one unit has had the valve adjustment checked. When the warranty runs out, I may do oil analysis and stretch my intervals out.
Fuel consumption is a little more than 1/2 gal per hour.
Tire life is a tough question because at first I had HD front springs that I shouldn't have gotten, so my front tires wore badly on the outside. I suspect I could have gone 1500+ hrs on the HDWS if it wasn't for the springs. Hoping to get 8-12 months on the street tires. That'll be around 40,000 miles.
The throttle pedal stops are adjusted to limit speeds to ~12mph and we run in "M" range.
I simply can not say enough good things about these little rigs. They're miraculous.
My other vehicles include 17 Ford trucks & vans, 5 school busses, a charter bus, an Escalade, a Town & Country minivan, several Turf Gators and Club Car XRT950s and about 50 golf carts.
I'll PM you about motorcycles...
