RD250C Rear Mudguard
« on: December 30, 2021, 02:38:47 PM »
When I started this restoration, my intention was to just put the bike back on the road (it was a runner when I bought it) with the minimum amount of restoration, and then do a full strip once I'd worked out was working and what didn't.

However, the best intentions get led astray, and I was seduced into trying to improve everything.............and didn't get very far!  So I'm going back to my original plan, so I'm putting back onto the bike the parts that have been restored, starting with the rear mudguard assembly.

The original mudguard was completely shot, so this one was sold to me at a very fair price by RD Jock.  Someone had converted this mudguard to a "D" version (which is complete sacrilege, as "D" pattern mudguards are available, and there are no "C" pattern mudguards) and so I had a friend fill the unwanted holes to restore the hole layout to a "C".  He also put the grab rail on a mill, and replaced the 5mm stud that supports the mudguard, and that had of course completely rotted away.  I also cleaned up the mudguard to grab rail welding that had been attempted, as a result of this mudguard support failing.

The rear light was disassembled, the rubbers removed using My Precious' "cut and shut" method, and the back plate sent for recroming, along with the grab rail and mudguard (Vehicle and General in Arseley, before anyone asks, as someone always does!).  Paul Scott painted the light bracket in 2-part, and the assorted shoulder bolts and special washers came from Webbs and Fowlers.  Yambits provided a number of the rubbers (and I find Yambits parts to be fine).  Next up, finish the exhausts so it can run again (now that it has 2 exhausts of the correct type).

Nice work

Can I just ask what sort of state was the mudguard in when converted from C to D and was it converted back again easily?

Hi

The mudguard was in good condition when I received it as a D, which is why it was worth converting back.  There was little rust, and normally it would not have been worth rechroming it.

The D fitting holes were filled with braze, and ground down to a polished finish, and then rechromed.  The brazing took a bit of patience, as you needed to be careful not to warp the mudguard.  The rechroming did show up some small flaws in the brazing (which were not evident until the mudguard went into the aggressive chroming process), but these are hidden under the rear lamp bracket and not obvious unless you go looking for them.

Its certainly better than the mainly-filler mudguard that came with the bike, when I bought it!
