pbblaster penetrating oil.. use 3 days in row (spray it) then try.. but if stuck.. use heat.. but will melt the drain seal.. so new plug after!

[@chrisstokley7687]

i like to bounce a 3 lb hammer on it.. soft blows.. helps loosen rust. allow pent oil to go in

Where is the oil filter on these?

[@simonh870]

Good video. I think that you should invest in a small funnel though as it makes filling 10x easier and you will spill less.

[@exonic5898]

I bought this bike 2nd hand and the drain plug is so rusted it won’t undo any advice ?

[@LukeModsxd]

Sand the top of the screw and weld a nut (in the inside) on the top of it, so later you can undo that welded nut with a wrench. Buy another oil drain screw.

Does it use the same oil for gearbox or do we change gearbox seperately?

[@zambaretulzambitor3713]

there is no gearbox oil in motorcycles engine oil is for all just make sure to use jaso ma or jaso ma 2 for wet cluctches

You not changed the oil filter?

[@saskay48]

I’m pretty sure they don’t have a filter it’s a mesh screen that just needs to be cleaned

[@williambritcliffe2211]

Doesn't have one only screen

[@motorm.m7583]

open the right side case(engine cover) and bottom right there is a mesh insert that u can rinse and put back in its a gold shh mesh but can be different depending on your bike
