I'm pickinI don't SEE anything else different?   I don't really need these and I just installed the complete kits from RPM in my set.  I was hoping for a decent set I could replace my broken post body with but it would be a total waste to bust these up unless ya'll tell me there is something special about these that would improve on my OEM '86's?

Thoughts?
You will also find that the float valve needle and seats are different between the gravity and pump fed carbs. The valve orifice in the pump carbs are
smaller in size, necessary to control the volume and pressure from the pump.
Damn good looking set of carbs.

I've been running a set of pump carbs on my '85 for about 8 years now.  I've run it at a pretty good clip on the highway (as we have a lot of those in Texas) almost all the way to an empty tank and never had a fuel delivery/starvation problem. 

I didn't change the needle seats and kept the single middle input.

I was even able to add a Colder double dry break fitting on the fuel line for easy hookup/unhook.  This keeps stress off of the petcock outlet.

Pat,
I think you will find that bearing had the perfectly measured amount of grease from the factory.

FJ Owners,
Thanks for the input on the carbs.  However, I'm gonna let them go to a new home.   With my set in good condition having recently been treated to a full rebuild with those stellar RPM kits, I'm in pretty good shape for carbs.  Also, sending them down the road will allow me to buy a few of the many items this bike needs to be properly restored. Hopefully, I won't regret it in the future.......

I've been able to do a little work on the chin spoiler as it certainly isn't perfect.  The dreaded "PO" of the '93 wasn't particularly handy...... this was his attempt to repair the small cracks in the spoiler:

He used some form of epoxy and embedded nails (looks like #8's) into the recess on each side of the spoiler.   :Facepalm:

I'm sure there are a hundred different opinions/experience on how to fix these cracks.  Obviously, the plastic is old and has been exposed to great heat, time is taking it's toll a bit on any of these.  Personally, I've done a fair amount of body work on CARS with plastic/endura bumpers and have found 3M structural bond to be fantastic for this type of repair.   It remains flexible (unlike the PO's nails) and is RELATIVELY easy to sand and paint.



I've obviously removed the nails and applied only enough of the 3M Bond to heal the small crack without immobilizing the entire area.  The thing still needs to be able to flex/expand/contract a little or I'm going to PROMOTE additional cracking.   I'm hopeful this will be as long lasting as the repairs I did to the bumpers on my TransAm, Z28, and Corvette.

The '93 Donor gives up another couple parts....
Whatever the "Dreaded PO" of my '86 did to destroy the fender, forks, and chin spoiler of the bike he also dented in the #2 & #3 exhaust down tubes.  Those on the '93 were perfect.  The part numbers matched so they're in place on my '86.  I'm not certain I would ever notice any sort of performance issue with these relatively small dents but it won't be an issue now.  Besides, it just looked like crap.





Well.... the bike is making some progress.... as I also continue to pick at the donor

If you don't like the discolored black head pipes on the 93. When you remove them, sand the black paint off, they are stainless steel and will polish up to a mirror finish.

FJ Friends,
Making a LITTLE progress this weekend.

Got all the mis-colored pieces prepared and primed.


Found the time to get the Pearl White onto the belly pan.

Gotta keep moving it around the lawn so it stayed in the direct sunlight while it dried.

Since it seems the correct decals are like unobtainium (?), I'm gonna try to paint the Stormy Red accent onto the belly pan when I paint the fender tomorrow (weather permitting).

I also received the front wheel bearings in the mail from RPM yesterday  :yahoo:  and a clutch safety switch from Evil-Bay. 


I may delay the bearings until the new tires are here.   Keep from pulling front wheel off twice....I don't plan on driving until the brake lines, tires, and front wheel bearings are all replaced..

Hopefully, the bike will be ready to roll at the start of summer. In the meantime, I have plenty of bikes to ride. :good2:  I won't drive this one again until I am SURE it is ready!!

THANK YOU FRED!!
Currently, I'm on a mandated "Corona Virus Spending Freeze".  I can get away with little stuff like front wheel bearings and $10 switches but anything big (like the decal kit) will get me a few nights on a very uncomfortable couch.  I will NOT attempt to paint the story red on the belly pan.     
Once the spending freeze is off..... I will order the decals!!
THANKS AGAIN FRED!!

Mounted the freshly painted '93 chin spoiler.


The fender pieces really need to set a couple days before I mount them.   But the red turned out really great.



The local OneSource PPG paint store did a great color match of the Stormy Red and Silky White for me. I'm using PPG OMNI paints & high build primers (aka. SHOPLINE). I paint all my bikes myself and I painted everything I could for the FJ1200 this weekend. I will be doing a repaint of the tank sometime soon.

This is the NEXT Mess I have to fix & paint.

FJ Owners,
I'm making really good progress on my project.  I'm taking care of neglected, worn out, and broken items on this machine and it runs fantastic now.

But there is still work to do....


  • New Wheel Bearings
  • Completely New Brake Systems including a New Rear Rotor - Rear was Damaged badly
  •     I replaced the rear master with the Brembo from the '93 donor (after it was rebuilt).
  • New Front Tire (Waiting on the rear to arrive)
  •      I'm going with Pirelli SPORT Demons  - I have Pirelli's on all my other bikes and have never been disappointed....
  • Complete carb tune with Colortune and Running Sync. Completed.
  • Waiting on my recovered custom saddle (using the pan from the Donor '93 I purchased).
  • Replaced all the instrument lamps with LEDs  - REALLY NICE & BRIGHT!
  • Replaced the rear turn signals with those from a SECA 600.  Exactly same style just slightly shorter stalks.  I thought the originals just stuck out too far and looked odd.
  • Checked cleaned, lubed as necessary, and re-torqued all motor mount bolts
  •     Improved the vibrations a lot but the new front tire made a vast improvement in vibrations, I suspect the new rear tire will really help with this as well.   The rear tire is 28 years old and hard as a rock!


I found this bracket under the fairing and I have no idea what it was intended for.   I find it hard to believe that Yamaha installed this bracket and then didn't mount anything to it:


What's missing?
Is this the correct horn for my bike?  It looks like an XS or XJ horn!

I'd appreciate a photo of this area from a stock '86 if anyone has one available.

Thanks
