bolt on performance parts do the most noticable difference on a 85 fj1100

Good to know

Ok,  I'll play....

In this order...Track school, front and back suspension, 17" rims, modern radial tires and brakes...then back to track school..

There is plenty of poop in the motor...

If you want bang for your buck, for you I would recommend a smaller front sprocket and a larger rear sprocket.

Switching to air pods and re-jetting the carbs is always a good option too. More air and more gas usually means more power but that's just my opinion.  It's not too expensive if your handy.

You appear to be new, but I'm sorry, that's the most misinformed opinion of carb tuning that I've seen in quite awhile.

The CORRECT amount of air/fuel will make the most power.  If you simply add more air and fuel, that's called accelerating (i.e. twisting the throttle).  

For a given throttle position (short of WOT) the filters do not allow any more air into the intake than the stock filter since the throttle plate is controlling the airflow.

I'll stop now.

Nicely put
im only 18 and new that.... then again im in school to be a certified tech.

wouldn't putting a smaller sprocket in the front and and bigger in the back increase low end in my opinion these bikes are pretty fast off the line,
i was thinking about going the other way, has anyone else gone bigger in the front and smaller in the back, better mpg? top speed? (NOT saying that the bike doesn't have enough top speed either?)

[Pat Conlon]

Yep.

Many of us have changed over to a 18 tooth front sprocket (stock being 17)
The larger diameter sprocket is a tad easier on the chain.

My '84 came with a oem 17-42 combination.
I find that for the longer rides (like the upcoming WCR and Colorado trip) a 18-41 or 18-40 combination gives good economy and a relaxed cruise yet still plenty of poop for corner exits. Gotta love that FJ motor!

For weekend mountain rides to Julian or Palomar, a 18-42 combo is fun.

Everyone is different. Different styles and different abilities.....it's all good.

[moonrunnah]

right now mine is stock (17-42) i guess
it rides good and the bike has lot of power but i think doing an 18 -42 or 18-40 i should still have enough torque in 4th gear  these bikes are fun and fast 

i want to pipe and jet it but i think im going to wait until winter time i dont want to interrupt riding season 

[fj11.5]

i recently fitted an 18t front havnt yet taken the Fj out to try it with the 45t rear that was fitted when I installed the 17" rear wheel, but have a 40t to use if I don't like the 45, not a lot of long straights down here

I learned this from David a while back. The only time you use more gas is at WOT. At every other throttle position its less gas used as less air needs to be taken in becuase the air is reaching the carbs at a greater velocity..Either way, you would use less gas to maintain the same speeds.

As for original question?
The FJ has tones of grunt, not so great handling unfortunately. If you really want a concise list, take a look in the files section. AndyB put up a list of almost every conceivable upgrade you can do to an FJ. If you want ideas, take a look at what racerman has done to his FJ - I hear it moves lightning quick

As to what moonrunnah said.. Im just 20, was 19 when I learned from David.

FJ1100turbo Pat gave you great advise to go fast learn how to brake and turn TAKE SOME CLASSES!!! IF you hit the brakes half way down the straight a way or don't know how to take a corner then you will be passed at every turn. I am a former desert racer and coached some young motocross riders, the ones who listened learned you win in the corners!!!
