Good Job !

Thanks !

Shameless self promotion bump to get this to the top of the page.  A few people have been asking about this lately.

The "Service Manual"  lists 265+2.5 ccs in each leg for the C5 and G5, page 02-7

My bad!! That was supposed to be B5 and G5!

You, that's what it say in my manual too.

I pulled only 155-165 out of the G5 I did, put 195 back in, and it was notably better, felt good to me.  I think the Pete Snidal manual for the old bikes says 200 too.  You could try the 265 if you want.

I dunno. I've been thinking about changing mine soon, as soon as it cools off a little. I've got the stuff, just gotta do it. Did you push the damper rods up when you did yours? The forks are a little longer on the G5, so I been kinda kicking about 220 around in my mind. But it's a play it by ear thing. I'm going to try to measure the height of the oil in the fork legs.

Both forks were totally drained, that's all that came out.

I'd say measure what comes out, I'll bet it's less than 200.  Then refill with 200.  It's very easy to add more to yours after if you think you need a little more.

Shamelin pointed out to me that the B5 also has the same style forks as the C5.  I could swear the first one I saw had G5 style forks and I'm sure I've mentioned that here and elsewhere.  I stand corrected.  Maybe they switched or maybe I mis-remembered.  Regardless, let's just say that any RE may have the C5 forks.  If you've got offset forks and don't have giant hex nuts on the bottoms of the legs, this tutorial is for you.

May be a silly question, but are the two forks swappable from left to right, or the left should only be used on left and the right on right side only.....??
Would the disk brake caliper fit on either fork ??

[GSS]

The two sides are different so these are not swappable. I can't comment on the new straight forks.

Related question on a long-dormant topic...

Are the springs on this fork similar to the old Iron Barrel springs, in that the top side coils terminate in a short section where they're wound solid and static, in full contact with each other?

Or is the spacing different on this newer fork?

Thanks,

Mike

[Ducati Scotty]

These are straight rate springs, same coil spacing for the entire length.

Excellent write up!!

This may be a silly question, but if all I want to do is check/top up the fork oil levels in by C5 EFI classic is all I need to do is to remove the internal 12 mm hex plugs?

You can't take out that top plug unless the fork leg is off the bike.  You pretty much need to take them out to do anything.  If you're just swapping oil you don't have to break it down once it's out.

Bugger :-(
I thought that it was a typo in the Manual "Take out front forks from vehicle, Remove Bolt cap, Check oil level"
Not a 10 min job then, like it is on my Beezers.
Job for a rainy weekend - after I buy a 12 mm allen key.

Many thanks again.

That's about as concise as it gets.  FWIW I could do that job in under an hour but I've probably done it 6 times by now.
