Adjustingthechainonamotorcycleconsistsoftwojobs:Adjustingchaintensionandaligningtherear
wheel.

Youcancheckthisadjustmenteasily, andyoushouldperformthischeckonaregularbasis.Alubricated
chainwillrequireadjustmentevery500to1000milesoncethemotorcycleisbroken
in.

Adjustingthechaininvolvesloosening(butnotremoving)therearaxle,looseningtheadjustornutsand
locknuts,usingascrewdriverbetweenthechainandtherearsprockettoremoveallkinks,aligningthe
rearwheel,tighteningtherearaxle,andtighteningtheadjustornutsandlocknuts.

Youshouldcheckthe
chainadjustmentduringyourmotorcycle’sfirstscheduledmaintenanceandat
everyscheduledmaintenancethereafter.Thebiggestadjustmentwillmostlikelyoccuratthefirst
serviceinterval,becausechainsdomostoftheirstretchingintheirfirstseveralhundredmilesofuse.

Whenthechainisproperlyadjusted,itshouldhave
about
15mm(or3/5ofaninch)slackatitsmi dpoint.
Therearaxleisloosedbylooseningtherearaxleboltand
nut.Therearaxleboltheadontherightsideofthe
motorcycletakesan18mmwrench;therearaxlenutonthe
leftsideofthe
motorcycletakesa19mmwrench.

Ifyourchainrequiresadjustment,loosentherearaxle.
