Hi, this is the elephant in the room type question. Why is there not an inspection plug/plate to check the primary case oil and alllow easy changing like an ol' fashion Chevy differential bell housing w/ inspection plug at just above the recommended factory level. You could use your little finger to inspect level, a suction gun to refill and...you know!
Yeah, Yeah I know the purists out there will probably object because of the fancy derby cover they have (including me), but you would think after 100 years of motorcycle experience (not you Glider...Harley), would have figured out a tasteful solution other then woodblocks stacking to level out and raise the bike, countless stripped bolts, wasted knuckle buster weekends, stained driveways and lotsa curses that even the Almighty would have objected to; would have inspired them...heck, we would probably have an aftermarket for someone building a chrome blockoff to make it pretty the way the old oil breathers were on shiny Chevy rocker covers!
Hey, found a quick and easy way to change the primary/clutch oil in my 2004 Sporty, less than 30 minutes and no muss or fuss!
1) Warm up bike and park very close to a sturdy wood fence. Turn off engine and leave in 2nd Gear, manuever bike so it leans slightly to the right of balanced, and put side stand down to steady it. You can put wood blocks under the frame to steady it. 2) You can drain the case via the plug and refit it with a fiber washer (12mm) threads just fine, the O-ring used just sucks, tossed it, clean the magnet and torque to spec. 3) Refill using exactly 1 Quart (1 Liter is just a tad more) which is 32oz as specified in the manual) of Spectrol 85W using a Spillmaster Funnel with on/off valve, strainer & clear hose ($6) via the Chain Adjustment Inspection Port, and your done (you can also do the primary chain adjustment as well). No jacks, no more knucklebusting, stripped screws or messing with the clutch/derby cover noise, and like I said in less than 30 minutes...way cool!
