I don't know what your frame bushings are made of. The ones I took out of my 200 were some sort of composite material. I used a punch and a hammer to knock them out. It ruined them (chipping them) so I replaced them with ones from CMSNL (pricey). I saw some for sale on ebay that were brass, and people would drill out the center bolt and install a zerk fitting to grease them.
was that on the frame or the swingarm? I know the swing arm are impossible not to chip but I'm not so sure about the frame ones
 
Gotta say it.....With that tank, the headlight/speedo fits the look perfectly......
Of course, I might be a smidge prejudiced....

I'll have to look into it. I'll get back to you. As I recall, the bushings on the frame, just sat on top of the swingarm. They weren't pressed in or anything. It was only those composite bushings that were difficult to get out.

Well as you know this build is totally asthetical driven nothing to do with mad musing of 'I wonder if ......'
I think its awsome, a smudge on the white side but nothing a silver rattle can can't fix. Thanks again
now back to keeping you away from your 2007 build any ideas on the frame bushings
 
Simon,
As those are essentially the inner spacers and there is NO (read zero) movement within that part, I have never had to replace them (Not even sure it's possible)....
When you tighten the so-called pivot bolt (don't know why it's called that as neither it nor the parts it bears on actually move in assembly) it cinches the collars in place... the bushings in the swingarm then pivot on the rigidly held collars....

That's with the wheel centered
but I found this on the net it's the specs for a cb250n swing arm which is 20mm wider at the rear axle so will elevate the rear wheel clearance, but is 20mm wider at the frame so I was wondering about remaking the frame bushes
Or making spacers
but if I go down this path I'm going to need to find someone to swap the frame with as I'll need a 175 frame to fit the wider arm into
 
Why not do it the simple way?......Cut the existing adjustment plate off just in front of the shock attachment loop....
Lap on a complete plate excised from another swingarm (only the tube section cut away) to the outside of the remnant, using its edges as a guide....WELD....Instant 8mm more clearance without changing the sprocket/chain alignment (if you use an 8mm longer spacer on that side....)

Note:... I HAVE used the clevis cut from an old shock and welded on an arm to allow eye to eye shocks.....
Since it will be threaded on the inside, You can use the original short bolt, and you'll gain more clearance....
Simply position it where you cut out the loop/eye on the arm....

You can space the chainguard slightly inwards IF you feel it's necessary, and the original hole (in the replacement adjuster-plate) will already be in alignment....

Sounds like a plan, I've just been reluctant to mess with the arm but your solution definitely is simpler and I know that even if I got the 250 arm to fit at both ends something would be wrong in the middle
as fate would have it I've still got the original rusted out cl175 arm which might be a suitable donor
thanks Steve

So got a little time in over the weekend
the cb160 speedo was missing its indicator and not rolling the odometer when attached to a drill
so I popped it open
at some point something had gone very wrong and ground parts to a paste of grease and metal and busting the spring
so not much hope of repair
I striped a working mechanism from a cd175 but it was smaller and the odometer numbers were smaller and the font not as nice
so I pulled it apart and mashed the cb160 odometer dials onto the cd175 odometer shaft and got a little creative with the washers
at work over lunch I tigged the arms that brace the dial onto the cb160 speedo then cut out the guts and bored a 20mm hole in the back so the modified cd175 speedo can slot in
 
Thanks I also recycled 35000 miles off the clock, which is illegal but I figured it would help me remember when to change the oil, & I'll never be able to sell this bike without creating my own fiche
Yes any potential new owner will be lost with the stock parts fiche and manual. Will be better off printing this project log :D
