| As was mentioned on another thread the other day, if your bike is 2001 or later, it amy have a slightly different set-up with the pick-up filter from the pic shown in the Haynes manual. Instead of a "bolt-head" on the filter, there is a cover palte, removed with a 14mm Allen socket, and thewn the filter is behind that again. Poke the allen key socket doen in there again.
And it's a very good idea to use a Allen socket adaptor for that, and the sump plug (10mm?), rather than using an actual Allen key. You can more safely apply a bit more force than way. Don't want to round off yer hexagons! |
