On my Bullet which is a 2014 model the bottom of the fork is straight the axel is in line with the leg there are no visible bolts that can be removed with the wheel on, there are large holes in the bottom on the underside of the legs I am guessing that if the axle is removed there may be access to the bolts through these holes as they are probably the other side of the axel, assuming my guess is correct these will not be drain or fill access points they will only serve to hold the fork together, all draining and filling will be done from the top by removing the leg, I hope this makes some sort of sense I would only know for sure if I was to start taking the wheel off and having a closer look but I am not about to do that at this time perhaps there may be someone who has taken the later Bullet apart may be able to throw some more light on this subject

A bit more info for your sore heads apparently if you remove the bolt from the bottom of the leg that holds the inner in place the inner will block oil from running out, but if you only turn it out a few turns and give it a tap upwards it will move the inner up a bit then remove the bolt to allow oil out, this is ok if you have the old style of fork were you can put new oil in from the top without removing the leg, otherwise it is a leg off job, these forks seem to have evolved over a period of time making various variations, you will need to make a careful check of what you have on your bike before starting, only let the oil out if you know how to put it back in, a good tip if you are changing the oil in a differential or gearbox on a car remove the filler plug first if you drain it first and then find the filler seized you are in trouble

So all this is because later bikes have a new design of forks (with or without the leading axle). I have seen the C5 fork pics on the US site before, it's still not fully clear (to my easily fuddled brain) how it all comes apart/goes back together.



With plenty of UCE bikes around that now have these forks (and a couple of years ago someone in Classic Bike magazine was even putting together a Redditch Twin with a set of C5 forks!), perhaps our hosts might oblige with a new item in the Technical Notes section!

Hi all
Thanks for the replies and interest in the story.
A quick update: After two emails, the factory hasn't got back to me at all. Sadly, I'm not surprised.

Les, could you possibly post a pic of your fork bottom? You're saying the wheel spindle is directly on the same axis as your forks and not on a lug?
I've never see any other design other than the one I have on an EFI. This one:

This is the best I can do with what I have to hand at the moment, a close up of the forks will have to wait until tomorrow when the shed opens and the light returns

Thanks mate. Not at all like mine. Never seen them before.
Really appreciate your effort there. I'll post mine tomorrow - weather allowing!
Best ones
Matt

I think 2012 was the changeover year when the leading axle forks (the type shown in your link) disappeared from the C5 models, with the the centrally mounted spindle type shown on Les' bike replacing them. A quick check of the on-line parts books might show if they're similar INSIDE. I have seen pictures of more recent B5 models where the leading axle forks are still fitted. A.

These are better close up shots
