I'd like to make it clear at this point that my intention is to attempt to get this pile of shite back to as near original, in terms of appearance and finish, as possible/affordable.  I'm not an OCD bolt counter (there seems to be some good natured 'hostility' to this approach anyway on the forum...) and there'll no doubt be numerous repro items involved in the build, but as I've mentioned in various other posts when challenged why I'm trying source correct parts, is that it costs just as much to restore a wrong part than a correct one ;)

 Yes, there are some strange comments from some folk  ??? but, I think most members would respect your aim.  There should be room for all approaches to RD ownership in this club, IMO! :)

Good luck with your rebuild!

It's your bike and your rebuild, I think it is bods claiming a "non standard" bike as "standard" that tends to rile the members of this forum

Please do continue to post updates as the Restoration section is my favourite section of the forum  :) I will look forward to your progress of both builds

Getting an RD out of the skip would have been an even better result  ;D ;D

OK, game on  8)

It's been a while since I started this post - 5years... were does the time go  :o (building RD racer reps and H2's basically).

I've had the chrome, paint(ish) etc. done over the years as well as trying to source all the parts I need (there'll be more bits I'll need during the build I'm sure), so now the workshop is clear I can start with trying to get this rare little beauty back on the road  :)

Engine nearly finished, PJME crank, new bearings/seals and 6th gear selector drum pawl.

Does converting it to 6 gears = 15/40 sprocket sizes?

Cheers

Great Stevie!  The UK 5 speed bikes were the same gears in the Gbox as the US 6 speed, just that you couldn't get the top gear because of the pawl plate difference.  So, UK 5 speed had the higher sprocket ratio to have similar overall gearing in 5th as US in 6th.  So, you have 6th working and the US sprocket ratio is the one to use on a standard bike, 15/40.   Cheers

Got most of the Chrome back, however I'm after a set of the round head bolts to mount the front mudguard stays.  I guess as they're NLA any spare ones are hard to find.  If anyone has a set for sale/swap (I've got quite a lot of spares that I'll be happy to trade) please let me know  :)

Just confirm exactly which bolts it is that you're after Stevie. If they're what I think they are, then it looks like CMSNL have them. Also, as they were/are used on at least 1400 models, then Yamaha might still do them.

Hi, I think you'll find they are all the superceded part number.  They are now flathead zinc plated bolts, don't ask me how I know...  :(

Yup... I've got some with 6's on but they were for 'B's' I think.

Noticed your location - do you work at one of the racing stables? Gr8auntiepat's brother works for Saeed bin Suroor and prior to that was a pro jockey with David Elsworth.
