Can anyone tell me the correct oil capacity for S & S sportster crankcased gearbox , oil is seperate from primary , no level hole of dipstick , i filled primary first then used the remainder of the oil to fill gearbox through hole for speedo sensor ( 450ml is what i put in there but would like to know the correct amount )cant find any info on S & S sight

 

mate da g/box oil is da primary oil same as better drain out from da bottom pri drain plug under left side of clutch housing & start again , fill thru da primary inspection hole in da top of pri cover da little 1 with da 2 little screws in it fill just 1 full ltr only, what model bike do ya have ,

on these S & S cases the trap door seperates the primary from the transmission , 91 to 03 style cases

Da trap door has cutaways in it for da oil to pass

is this a complete S&S Sporty, these engines cum with no g/box or pri you must use ya own stock parts or email S&S tech help line 

street or race bike , who built da engine

S & S trapdoor sealed no cut outs , just found info on xl forum 18oz primary 10oz gearbox

i wouldn't be going too far with only 10 oz in da g/box

thanks for the replies , 100' sounds like a good bit of fun , ive put a set of 1'3/4"drag pipes on mine to get it running but not happy with with top end or noise ,will try to modify my supertrap 2into1 to fit until i get time to build up a bigger diameter system

89" sidewinder kit i think S & S call it , sorry i was refering to the outside diameter , have just made my supertrap 2 into 1 fit , on the dyno power flattened off over 5ooo rpm with the drag pipes , running 555 cams so should still be building power over 5000 rpm

Thanks Hoodeng for the advice , the bike is a sand drag bike , will be racing this weekend so will see what it is like on the track & go from there , cheers
