The vibration just isn't that bad on an SOHC4.  And, the fuse wire mass is so small.. Metal fatigue? Seems so unlikely.

You should try riding on UK roads TT ;)  Trust me when I say the vibration isn't generated by the bike >:(

I certainly can't speak for UK roads.  But, I do like running on the back roads up in the hills that really aren't maintained that well.  Mud clods from farm equipment, tractor wheel and crawler track road impressions, washboard, potholes, and uneven pavement is pretty common.   We don't get frozen earth (no frost heave) around here, but our rain is a 3-4 month affair that undermines and hydraulic pumps the road base under many unsealed cracks in the tarmac.  The local politicos aren't keen on having a large and/or active road repair regimen, by any means. So, any repairs made don't happen till late summer... of the following year.
 All my bikes still have the glass fuses, and most are original. Did I mention the railroad tracks I crossed on my daily commute for 15 years?  I think I have experienced road vibrations, too.

Best of luck to you!

Hey Jimmy, how much would you charge for making a second one of those there fenders?

Finally got the wiring all sorted out. If you haven’t taken the time to relay out your headlight, find the time to do it before riding season starts. The difference in the garage is very noticeable. Can’t wait to get out on the road and see exactly how much brighter it is.


I really dig the cleaned up wiring, and those multi-wire connectors...nice idea.

so are there two relays...one takes the wires from the hi/low switch, and the other one the "always on" wires? then you have a direct run from the battery that feeds into both?

Also, great fiberglass work on the seat and fender. Looks like you know what you're doing. What weight of glass do you use and how many layers? I am curious -- what kind of resin are you using? West System?  I too want to make a solo seat for my bike, using a stock seat pan and foam/fiberglass. Then I can switch between stock and solo.

Cris

What fender do you want?
Stock Suzuki GS750 copy or the soon to be widened variety.


I'm not too sure Jimmy, I'll be running a stock 550 front end with a 110 tyre, what are you running that requires the fender to be widened?

Jimmy- Thanks for the info, that Vintage Connections site has some neat stuff. The tank that guy made is pretty unbelieveable...90 hours of work too...WOW. I think, to keep things simple, I'm going to go the fiberglass over foam route, and make mine a one-off. But I think the process of making a mold is the better way to do it, and will produce a lighter part with a nice finish. Looking forward to keeping an eye on your progress.

Personally, I don't think cafe humps should be taller than the seat, but that's my style. It looks more grotesque from the side.

The rest of the bike looks sweet! And thanks for answering my question as to how Kerkers look/fit on 550s.  ;D

Have someone take a picture with you sitting on the bike in riding position.  Isn't that tail piece supposed to reduce turbulence at high speed?  If so, it should continue the line your back arch takes while mounted.

If it is just for show, without a person on it, then it can be whatever pleases you.

I'm loving the swingarm, and the fork conversion ;D

If the hump is purely for aesthetic purposes it does need to lose some height IMO. Personally I like the ones that copy the form of the rear half/third of the tank, but that's just me :)

+ 1 ....my thoughts exactly!

While not exactly in the most aerodynamic position you get the idea.....




rest of the bike looks very good!! Job, well done!

To me it looks like it "belongs", with a rider on the bike.  And, it is easy to visualize air flowing over the rider and then the tail section meeting more gently at the end.  If that makes any sense. ::)
I'd expect less wind turbulence to blow up your jacket or past your belt near the transition.  Bad on warm day, blessing on a cold one.  Such are design trade-offs.

Remember also, that lighter colors "look" bigger than darker colors.    And, curved shiny light reflections turn those sections invisible.

I expect motorcycle show purists won't like it that big.  But, who are you trying to please?  What do YOU like?

I've seen very art-full chairs that were beautiful to look at.  But, sitting on them more than a minute verified exactly what their purpose was, and why they weren't common as anybody's furniture.

The rear fender is from a Suzuki GS550. It’s a little smoother and rounder than the CB550 fender and should complement the café seat nicely. To make it fit the CB550 I cut the front mount off my CB fender and bonded it to the GS fender with a little fiberglass and bondo. Bondo is an excellent adhesive and with some more filling and sanding I’ll have all the holes filled and the CB mount blended in prior to making a production mold.


I did the same thing with my first 550 but used a stock seat. I welded the two pieces together which was hidden under the seat. It turned out nice and clean. The GS fenders have nice lines. Sweet bike, tons of great work, curious to hear how it rides out.

yeah, +1.

I think it fits the bike somehow. The bigger tires, bigger discs...it works. You could stand to lose a small amount of height, but not sure how easy that is to make happen.

your bike looks great though! 

Thanks again for the ignition. My bike is running great, I was out riding tonight. fun fun fun.

Bike is looking very nice, just wish mine was this far along. 
Couple questions for you.  One, did you ever come up with a way to drive a mechanical speedo? Two, any idea how much larger a diameter your new sprocket is from the old?
Thanks, keep it up.

Thanks for the info on the speedo FJ, as I am actually trying to find one for a 25mm axle, so that is absolutely perfect. 
Looking forward to some more pics.

Would you be willing to make a second rear fender if so how much would you want for one? Would ask about a front fender but like the other member who asked for one i would need a stock width part there.
