What if the span portion of the brace fits too tight? That was the case when I installed mine, I had to gently tap it into place. The result was a little stiction at first but loosening the axle pinch bolts and working the forks took care of it. If the fit was tighter I would have been out of luck.

Mine is the same, the brace fits snugly between the tubes, have to tap it a little to get it in.

Myself I originally found I had to tap it in. But later I found that I was not holding it perfectly square. Meaning I had a slight tilt to the side or front back etc. As soon as I get it lined up just right it will slide right down w/o tapping into place. That may not be the case for the ones just mentioned. I dont know. Just wanted to add that experience. Before tapping into place make sure there is no side to side, front to back tilt going on. Assuming there is only a few thou clearance it will take very little angle to eat that up and make it seem like its too tight.

2) fork oil. It wears out. also different viscosities will dramatically change the ride quality. Thinner is more reactive as it moves through the damper rod, but may not provide enough damping. Thicker damps better, but may be to harsh. If you want to set up the fork, you may need to try a couple different oil viscosities to get what you're looking for.

To back peddle a bit, I see a lot of members replacing OEM with 15 wt fork oil.  I'm not a gung-ho
technical rider, and I like the bike's ride, but the front end is still a little soft for my liking.  Will 15 wt oil
help this, or do I need to combine a new set of springs with heavier oil?

Fork Oil Change is towards the top of my 'to do' list.

Thanks.  Marty.

I first tried only the 15W oil and did notice a difference, but eventual changed the springs out to the sonic 1.2 straight rate springs with the 15W oil as well.  You might just like the oil change by itself.  You can also do the cheap thing and cut the stock springs down and add a PVC tube with washers to make up the difference in overall pspring length.  I beleive this is noted in the thread somewhere.

If it is too tight you'll spread the forks and have exactly the same situation as if it was not tight enough. Just remove some material untill it fits just right. If it is close but just a little tight may just need to remove some paint from the forks. Use a strip of plumbers tape, emery cloth or sandpaper and work on the inside of the fork, like shoeshine motion. If it's a lot of material to remove then you'd want to either machine it or return it.

Steve, regarding the fork brace shimming, is that specific to a particular brand?   Mine had a brace installed when I bought it used.  I've had it off and back on for various reasons, but never rode the bike without it.  I'll probably give that a try to validate it's working ok for me, but curious if your shimming need is specific to a brand.  thx....

All, I don't recall the year of the change, but earlier Connies (mebbe 99 and earlier) the diameter of the fork tubes was not as exact as the later models. (I think the area where the Fork Brace is mounted was cast on earler years and machined on the later years).   You can look at Murphs site to see the exact years. He sold fork braces for earler years and for later years. 

For that reason the earlier model Connies are more likely to require shimming.
But it is a good idea to check for stiction when installing on any bike....

Ride safe, Ted

Hey Steve I used soda can shims.  They worked great.

One thing I did notice is the fork brace and the fork may not be the same shape of round.  I had to custom fit shims that were shorter then the brace opening because if I shimmed all the way to the edges the brace would no longer fit onto the tube correctly.  Hard to explain but not that hard to figure out when doing it.

I sanded the top of the fork tubes to make sure that the brace is fitting as it should. The brace fits between the tubes snugly, requires just a hand push to place it in position. Tightening one clamp produces no measureable clearance on the other side.  Installed the other clamp, went for a ride, seemed to be an improvement in ride quality.  However, I returned to the garage, removed the brace, went for another ride, very nocticeable improvement in ride without the brace. I'm a bit stumped on what to try next.  :smiley_confused1:

What year model are you installing the brace on?
It sounds like your fork tubes may not be aligned. As they move up they may be binding a bit.

Easiest way I know to determine that; is to raise the front end, remove the fork caps/springs and move the wheel up and down (full travel) to check for binding.

Ride safe, Ted

It's a '98. I will be pulling the forks for a fluid flush sometime in the next couple of weeks, I'll be able to check for binding at that time.

You had the year, '99s and up had the factory fork protector's so hence the tubes are machined for the protector. '98s and earlier have more potential for variance. Technically '99s and up are more precise since they are machined for the protector, but there are still manufacturing variances and other factors. A better chance for the braces to fit perfect, but not a guarantee....
