First Question ;
The front axle boot on my 250 Quad is torn. Does anyone make replacement boots for this CV joint that are split like those for autos , so that they can be put on without a complete tear down of the axle shaft ?

Second Question;
Are after market guards available for the above mentioned axle joints ?

Third question;
This will probably date me but are different heat range spark plugs available for the 250', and if so what is the best plug for low speed , short runs ? ( I use my unit to run back and forth to the shop from a home construction site)

Any help or suggestions are appreciated.
