-Engine loses oil through output shaft / clutch seals – blocked/kinked engine breather or old worn seals, also possible excessive blow by
from worn piston/rings but this should be evident from white exhaust smoke long before losing oil through breather.
Suspension
-Shock feels springing, no rebound damping – check shock pressure 100 – 150 bar ( using shock pump ) If loses pressure quickly seals
gone replace shock
-Clunking from rear over bumps – check shock bushes for wear, check shock bolts are tight, check swing arm bolts are tight, check
swing arm bearings for wear, check rear wheel bearings
-Oil leaking from shock – seal gone, replace shock
-Back end very soft – check shock preload locking nut is tight. Re-adjust as necessary, if does not remedy spring is worn, replace shock
-Forks leak oil – replace seals & re-fill with oil ( 175 ml per leg 7.5 – 10 weight )
-Forks have no or little rebound – replace seals & re-fill with oil ( 175 ml per leg 7.5-10 weight )
-Forks are soft – replace springs
-Fork stanchions are pitted/rusty – replace form
Brakes
-Feel spongy – check pads for inconsistent wear, bleed system with fresh DOT4 fluid
-Feel firm but do not work – Pads incorrectly fitted & thus unevenly worn or wrong size disk – inspect pads for inconstant wear
-No feel – lever goes full travel without actuating brake – rear brake – adjust master cylinder actuating rod, check for leaks, bleed,
replace brake assembly
-Metallic noise during braking – replace pads
-Front/rear brake dray – inspect and clean caliper, use copper grease on caliper floating pins, warn pads ( replace ), warped brake disk
( replace )
-Grabs ( shudders ) under braking – loose caliper bolts or pins, worn caliper housing
Other
-Chattering from rear – chain tension / worn sprocket/chain
-Play in rear end – loose swing arm or shock, worn swing arm bearings or shock bearings check & replace
-Knocking front end – loose or worn headstock bearing
-Steering notchy – headstock bearings too tight or worn
