BASIC DAY-TO-DAY MAINTENANCE: CHECKING A N D ADJUSTMENTS
Bad Flooding Sometimes a carburetor will pass fuel out its overflow tube from the instant the fuel tap is turned on. This condition can be brought about by dirt fouling the float needle, o r an excessively worn needle valve or seat. First, remove the float bowl and carefully take out the float lever hinge pin, and then remove the float and lever. With a suitable container, such as an empty tuna can, under the carburetor, open the fuel tap and allow some fuel t o run through the unimpeded float valve. This should wash out any dirt particles. If dirt is obviously a problem, the fuel tank may have t o be removed and cleaned. Test the float valve closure after reassembling the float and lever into the carburetor. CHASSIS ADJUSTMENTS There are a number of adjustments and maintenance procedures necessary t o keep the general chassis in tune on your Bullet. These may be divided into the following categories:
Front Forks A. LUBRICATION Lubrication of the fork sliders is taken care of by the hydraulic oil in the fork legs themselves. There should be about 200cc of hydraulic oil, SAE20-20W, o r ATF in each fork leg. If there are no signs of leakage, and no indications of "bottoming" - a heavy clang when the front wheel is deflected suddenly by such things as speed bumps there is probably nothing amiss with fork oil level. To check level, remove the cap screw at the top of each tube (in the casquette casting), and insert a piece of rod about 2 feet - 60cm long down the hole t o use as a dipstick. If you feel around, you'll feel an obstruction partway down the tube, and the oil level should cover this obstruction (the top of the damper rod, or "fork spring stud). B. STEERING HEAD ADJUSTMENT Steering head adjustment, although seldom necessary, is easily checked. The front forks are mounted in a fork head at the front of the frame, in adjustable ball bearings. If the bearing cups are not sufficiently tight, the front end will be allowed t o move in unconventional ways, affecting handling in a negative manner. To check for looseness, simply apply front brake while straddling the machine, and rock it fore and aft, paying attention t o the area of the fork head. Any looseness will immediately become apparent. To adjust the steering head bearing clearance, first loosen off the two fork tube clamp bolts ( I ) at the bottom of the casquette. Then loosen off the adjuster clamp bolt (2) at the top rear. N o w you will be able t o screw down the top crown adjuster nut (3). Run it down until it's tight, then back a bit until the front end turns freely in the fork head. (Machine on center stand with front wheel of the floor.) Re-tighten the clamp bolts when finished.
