B. Brakes check and adjust as described in owner's manual.
C. Horn check for proper operation.
D. Lights check all lights for proper operation.
E. Axle Nuts be certain both front and rear axles are properly secured. Cotter pin must be installed in
castle nut on front axle.
F. Chain check and adjust as required.
G. Steering Damper check for proper operation. The damper is intended for use at high speed only. Do not
overtighten.
H. Idle adjust idle, if necessary, by visually checking the position of the carburetor throttle valves. Adjust
cable adjusters on top of carburetors so that, with throttle grip closed, 1/32" of free play can be felt in the
throttle cable at each carburetor.
I. Oil Injection Adjustment the entire oil injection system is designed to provide the correct oil mixture at
all speeds. The only adjustment it will ever need is the cable adjustment.
• The oil pump volume is affected by the position of the throttle and varies from 20 to 1 mixture at full
throttle to 100 to 1 at idle.
• To adjust the oil pump control cable, proceed according to the sequence as outlined under Oil injection
System, 175 DT, Section B, page 51.
8. BREAK-IN: ALL MODELS
A. First 250 miles: The oil injection tank is filled with 2-cycle oil and the fuel tank is filled with 20-1 gas/oil
mixture. Do not exceed 30 miles per hour (40 mph w/ 175DT) for the first 250 miles. To insure proper
break-in and to prevent spark plug fouling for the first 250 miles, do not run at any one constant speed.
• 250-500 miles: Fill the fuel tank with regular gas only. Be certain that the oil injection supply tank is
full. Do not exceed 40 miles per hour (50 mph W/175DT) Continuing to vary the speed during break-in
will insure for proper break-in.
• 500-750 miles: Do not run continuous maximum speed. Check the oil injection tank daily. Caution:
Engine will be severely damaged if tank is allowed to run dry.
• Note: A 20-1 gas/oil mixture is used in addition to oil injection for the first 250 to insure proper break-in
and priming of the oil pump.
B. Never run engine at constant speed during break-in. Run it up to the maximum allowable speed for a
minute or two and then back to lower speeds.
C. Clean the spark plugs every 100 miles during break-in.
D. Change transmission oil after the first 250 miles and after 750 miles. Then change at regular intervals
thereafter.
E. Check and recharge the battery after the break-in period. At slow speeds the battery does not charge at
the normal use rates.
F. Check frequently for normal chain stretch and adjust as required.
