Just wanted to post a little about the progress.
Got the frame back from paint last week, and the chrome finished
last week too. Two weeks early,  :toot:
Both came out very well. I am happy with the vendors I chose.
  Try and make a long story short. I ordered a pair of Ikon Shocks
for the Gilera 175 project I was working on before the RD showed up.
Since the suspension geometrys were very close I chose to install the
Ikons on the RD instead. Only change was the ID of the eye bushings.
From 15mm on the Gilera to 14mm on the RD. Got the new bushings
and press fit in the new ones.
Installed the triple trees, tapered roller steering head bearings and fork
tubes. Along with new headlight ears and the tube clamps for Woodcraft
Clip Ons.
I (had thought) I would use the nifty top triple clamp I got from HcvCycle.
Dumbazz me did not read the web site page. These are for the "Disk Brake"
model of the RD250. They are too wide for my "Drum (dumb me) Brake".
More on that later after my embarassssment wears off.
So far, looking pretty good.
Next is to fit the wheels so I can get it off the work bench.
I need to upload some of these pictures to PhotoBucket so they are larger
and clearer......just too lazy after several days of hard work around the house.
Hope you enjoy the teazer pictures.
Cheers, Jeff

Well?.... she's a roller. Got the wheels installed as well as the
chrome fenders, Air, Battery box and Rect/Reg.
Clip-ons and headlight ears. I left the protective covers on the
Ikon Shocks, for now.
Hope Ya'all enjoy.

looks great. side note, swap clip-ons from left to right, the bars should point down, they appear to be pointing up in the pic.  :twocents:

thats going to be one clean build.  :metal:

 Thanks Mark for the suggestion. Yes, as is, they are rather flat.
I plan the swap and flip them, try all the possible positions till I
find what feels ( works ) best.
I have an old pair of TeleFix clipons that can be adjusted in about
any angle and direction on could think of. Only problem, they are for
a set of 37mm fork tubes.
Cheers, Jeff

Are you keeping the Butterfly Blue?

Absolutely. It's my favorite color. Plus the tank(s) and side panel are
in really good shape for a 46 y/o bike. Heck, it sat in a garage for 40
of those years.
With the exception of the clipons and headlight ears and shocks. I will
try my best to return it as close to stock condition as possible......Well
the Excel Shouldered rims were an upgrade I fell in love with.
Cheers, Jeff

You might want to consider putting in some stops on the triple so the clipons can't dent your tank. Some people have used screws for this. There's more info here if you want it.

so-cal-sdr200

Yep! I swapped and flopped the clipons this morning to find the
best position possible.
I have ample room for both my hands and the (fork clamps) to clear
the tank at full turn. Maybe 3/8 to 1/2" clearance.
If it had a "tank slapper" and the forks twisted in the triples, I guess
you could contact the tank, but, it would take one hell of a twist to do that.
I am always grateful for all observations and suggestions. Keep'em coming.  :patriot:

Glad the bars have plenty of clearance. Keep up the progress!

PM Joe spooner and get a set of his rearsets made...
Stock foot rests and clip-ons don't go very well unless your GUMMBY!
Your doing some very nice work!

Tell me more about Mr. Joe.. And his rear sets! His he a member here, does he have a shop/business?
Or just a machine specialist? Yes, I was wondering about the Gumby issue if I was to go with the
stock foot pegs.
Since I am using the stock upper triple clamp, I could go back to using a regular handlebar set up
rather easy if the clipons turn out to be a hassle.
I would like to use rear sets, but, all the ones I see are rigid (solid) mounts. I would like a set that
fold up. One for ease of use for the stock kick start and if the bike ever happens to fall over. Heaven
forbid!!! Vintage Smoke are the only set I have seen that fold.

And thank you for the compliment! I appreciate that from a man with a much talent as you have.
Cheers, Jeff

He's on here as Jspooner I have a set and they look like they were from the factory. I used OEM rear pegs for the front. Yea they do fold, price is reasonable too.
Edit: I guess you can't see the pegs that well from that pic, you get the point though.

Very nice indeed.  Something nice about  that 1/4 litre.
