After removing the filter & having a good look I am sure now you must not remove the plugs. If you do the oil that goes through your cooler will not get filtered, in fact most of your oil will probably not get filtered. You must install the filter adaptor so the oil goes through the filter then through the cooler & returns back in to the motor.
It is taking me a while to get this done (about 4hours so far) but I am changing the motor oil & filter, staying with HD SYN 3 ,changing the gearbox oil to Redline Shockproof, changing the primary oil to Redline MTL , polishing the paintwork & polishing all the chrome & wheels as I go. Its amazing the places those bugs get into!
I have a new problem now, when I drained the primary last night there was 2 reasonable size pieces of what appeared to be pieces of a gear stuck to the magnetic drain plug & I also thought the primary chain appears a bit loose so I will remove the primary cover this morning so I can have a good look (can't see much at all through the inspection covers)
Will post some pics later
Cheers
