INSTRUCTION SUPPLEMENT FOR 1987- LATER YAMAHA YFM350 WARRIOR Removing stock carburetor and cables. 1. Remove seat and gas tank. Make sure fuel petcock is in “off” position. 2. Remove throttle cable paying close attention to routing, as the new cable(s) will need too be routed the same.
NOTE: Modification of the stock thumb throttle housing will be required in order to achieve wide open throttle. Figures 4 and 5 will show the mods. Figure 4. Mod number one is to remove material on the outside throttle stop that limits the thumb lever travel.
6. Adjust throttle cable to take up the slack. Note: When throttle cables are properly adjusted, there should be approx. 1/8” of free play in the throttle. 7. After throttle cables have been adjusted the handle bars should be rotated from full right stop to full left stop while opening and closing throttle to ensure smooth operation.
