What makes a camshaft have play


the cam shaft is held in position by a set of thrust washers normally behind the sprocket or gear between the cam shaft bearing block and the sprocket or gear
end float or around .020 " is acceptable as it allows oil to lubricate that thrust washer but any more ( check specifications for cam shaft end float ) would not be acceptable as it tends to load up the links of the timing chain
if the cam is gear driven the excessive end float will alter valve timing

Tip

Changing your drive chain


When changing the chain on your motorcycle, don't just pull the old one out and then remove the covers to thread the new one back on. With the transmission in neutral and the rear wheel off the floor, break the old chain, then using a master link attach the new chain to the old one, pull the old one around the countershaft sprocket and bcak until you can grab the new chain. Disconnect the old chain and you are ready to connect the ends of your new chain.

Put the bike up on the main stand. Remove the rear brake caliper assy. Loosen the rear axle and pull it out. Now pull out on the wheel, pull it away from the rear gear housing, the wheel will disengage a gear inside and then it is ready to pull out the back.

hi you could check the rear sprocket bearing, firmly grip the sprocket try rocking it from side to side, you should not have to much exsess play, have you refited the spacer that fits between the sprocket housing and the wheel? it is easy for this to be omited as it can fall out when sprocket housing is removed from the wheel, this will put undue stress on the bearing inside this hub as the wheel is tightened causing early bearing failure, you will need to remove the wheel again to check this, you may also check the conecting link has not been over riveted causing the link to become tight, check the link manualy compare it to the other links for stiffnes this will also make a clicking noise, is the sprocket a 1 peice construction on the rear, using a scredriver or similar rest it ontop of your swinging arm, rotate the wheel slowly and check for runout in the sprocket,was this noise apparent before you fitted the chain and sprockets, check security of the front sprocket, remove cover and check there has been no contact between chain and cover and or metal strengthening bar, run machine with cover removed to eliminate it from poss cause, hope this helps

Sprocket replacement


pull the front case cover off that is over the sproket, then you will remove the large bolt that retains the sprocket to the output shaft of the trans, this will require a 1/2" drive air impact gun (like tire shops use to remove wheel lugs), u will also need a good quaility gear puller to get the gear off as it is a press fit.
