derby cover
This is probably a stupid question but I am changing out the derby cover on my bike for a new one. Do I just unscrew the 5 screws and swap the covers or is there a gasket or o-ring in there that needs changed or is there anything in there that I need to worry about falling out?

RE: derby cover
Bike has to be upright or the fluid is gonna come out. If you have a stock derby cover, it will have an o-ring in the groove (depending on the year) and when you put on a different one, you will have to use a 25416-99C full gasket. The screws are T-27 torx, and don't strip them out. It's simple really

RE: derby cover
You should buy a new gasket, but if you're careful taking off the old one, provided it is the full one, you may be able to get buy using it without any leaks until the next service. I've reused a couple before without any problems.

RE: derby cover
'05 EGCwith a cardboard disc gasket,I have reused it3 times so far. Just wipe it, and the sealing area off, & make sure to install it right side in, it's marked. Like Dawg said, the bike has to be straight up, not on thejiffy stand.

RE: derby cover
I had the exact same question about a year ago, LOL. It is very, very easy. Just make sure you use the correct torx head, a T-27. Take care to not strip out the screw heads, as that will cause you a couple more issues. My '05 had the full round, cardboard gasket. I reused it when I did the derby cover swap, and put a new one on when I did my 5k service. Didn't have any issues to worry about. One bit of advice, if you feel like the head is starting to strip out, stop. Take you bit driver, place it in the screw head, and give it a lite rap with a hammer, and turn it at the same time, to help break the seal. Sometimes, the srews are way to tight.

RE: derby cover
also, throw the POS torx bolts away. Go down to Ace Hardware and get chrome allen head bolts to repace the torx bolts. less chance of stripping the heads when removing to change the primary oil, and much easier to work with.
