no need to take off derby cover??
 
as I plan on changing my primary fluid this weekend, I wonder if I need to buy the gasket kit. im going to take the inspection cover off any way to look at the chain, why not just pour the fluid in there, and not disturb the derby cover/gasket? its at 5k miles. Ill be watching the fluid for any metal chunks. but is there a reason to replace the derby gasket at 5k? 10k ever?

thanks

At 5 K miles you should also be adjusting the clutch.
(every 5k in the maintenance schedule)
That requires opening the Derby Cover.

You should also confirm the primary/transmission fluid level is at the bottom of the clutch spring with the bike upright through the Derby cover.

I'm not a clutch rider, so I check the primary chain and put 28 oz. of 20-50 oil thru the inspection cover:shhhh

I've reused the derby cover gasket many times.
It's good to have a spare on hand but I haven't had the old one leak yet as long as it goes on right.
The proper level can't be asserted without seeing through the derby cover.

EXACTLY. !



Every Service should require inspection and adjustment.. especially if you have the stock spring plate

derby cover
 
ok. good point. take it off to make sure the level is ok. but can reuse gasket most likely.

as far as clutch, HD is doing that. I made a deal with them that they do all 5k checks besides fluid changes, as they charge 2 hours and its a brainless job. well, when you have xlforum behind you. Yeah, id like to think Id have a forehead slap moment after dumping a quart into the case thinking. how do I know the level is just right? lol. thanks yall.

Many of us give advise based on our own past mistakes.
Here, I'll do the head slap for both of us. :doh
:laugh

I dump a quart in the primary every time I change the gear oil. with no ill effects. I have always done this and many others I know do this as well. My local Harley shops does this as well. Never had a problem.

A guy I used to work with would have 2 containers ready. One he would dump the old oil from the primary into and the second he would pour the same amount of new oil into and pour back into the primary. It works as long as you know you have the correct amount of fluid in the primary. Personally I was going to try it but not knowing exactly wear the oil level was at I just opened it up to be sure wear the fluid was to make sure and do it right.
