Poor Idle or Low Speed Performance
1. Check for an incorrect pilot screw adjustment
2. Check for damaged or loose intake pipe and air filter housing hose clamps. These
conditions will cause an air leak
3. Perform the spark test in this chapter. Note the following:
a. If the spark is good. Go to Step 4
b.
If the spark is weak.
Perform the Peak Voltage Testing
4. Check the ignition timing. If ignition timing is correct. Perform Step 5. If the timing is
incorrect. Perform the
Peak Voltage Testing
5. Check the fuel system as described in this chapter
Poor High Speed Performance
1. Check ignition timing. If the ignition timing is correct. Perform Step 2. If the timing is incorrect.
Perform the
Peak Voltage
2. Check the fuel system as described in this chapter
3. Check the valve clearance as described. Note the following:
a. If the valve clearance as correct. Perform Step 4
b. If the clearance is incorrect. adjust the valves as described in Chapter Three
4. Incorrect valve timing and worn or damaged valve springs can cause poor high-speed
performance. If the camshaft was timed just before the UTV experiencing this type of problem.
The cam timing may be incorrect. If the cam timing was not set or changed. And all the other
inspection procedures in this section failed to locate the problem. Inspect the camshaft and calve
assembly
FUEL SYSTEM
The following section isolates common fuel system problems under specific complaints. If there is a
good spark. Poor fuel flow may be preventing the correct amount of fuel from being supplied to the
spark plug. Troubleshoot the fuel system as follows:
1. Clogged fuel tank breather hose
2. Check that there is a sufficient amount of fuel in the rank
3. After attempting to start the engine. Remove the spark plug and check for fuel on the plug tip.
Note the following:
a. If there is no fuel visible in the plug. Check for a clogged fuel shutoff valve. Fuel filter or fuel
line
b. If there is fuel present on the plug tip. And the engine has spark. Check for an excessive
intake air leak or the possibility of contaminated or stale fuel
NOTE
If the UTV was not used for some time. And was not
properly stored. The fuel may have gone stale. Where
