KNOWN FAULTS 1 - 1
Fan touches Radiator. Remove tank, look down back of radiator &
check that fan shroud has about 3mm (1/8”). The fan mountings are
slotted but if there is not enough adjustment, trim the front of the shroud.
Long rear engine bolts can seize. Remove the bolts one at a time,
clean off any corrosion and coat them in ‘Copper Slip’ or grease before
refitting. Torque 30Nm.
Tank filler thread can be broken off. Over tightening the tank cap
can cause the threaded part of the tank neck to be pulled off the neck.
Not easy to effect a good repair, but some resins and super glue can be
used and may repair the damage.
Fork seals leak. Seals on upside down forks do not last very well.
Fairly easy to replace. ‘Leak proof’ seals can be used and are
guaranteed and can be pushed in with your fingers. Available from
dealers selling ‘bike bits’ parts.
Body panels crack from fixing screw holes. Remove all screws and
refit one at a time loosely. They must go in without the panel having to be
stretched. If they will not go in, enlarge the holes slightly then all should
fit. Nose crews first, then tank screws, then the big screws in the middle
of the panel. After 228-70862 a revised system of fixing the tank panels
was used to stop the cracking. To update an older bike:
Screws only in the rear fixings to the tank. Spacers under the crescent at
the front of the tank to stop it clamping the panel tight. Cross bar is in two
pieces with rubber washers under fixing bolts. Strips of draught excluder
along top of tank in front of rear panel fixing screws.
Rear suspension linkage. The linkage is fitted with grease nipples.
Don’t forget to grease it occasionally.
