All,

I might be going insane - but I have a 36mm on a 1/2 inch impact driver turning it lefty loosey to get it off - no dice.

Any tips?

apply the rear brake by sitting on the bike or with a piece of wood jamming the pedal down also you can put a piece of wood thru the wheel over the svingarm. If there is a lock washer
(I cant see one in the picture) bend the tabs down then use a long arm wrench while sitting on the bike with your heel pressing on the rearbrake . Or just use impact driver  .
Sometimes people has used loctite on the frontsprocet nut....bit i would not use a torchflame to free it because of the chain o-rings and the transmission seal
When replacing use a new lock washer place some grease on the splines and torque to 85NM.
It looks like you need a new frontsprocket too

Yeah! I tried a bunch of tricks - eventually I used the 2x4 jammed against the rear wheel and that did the trick. No lock washer and not torch!

Yep - sprockets coming out, new sprockets and chain for sure!

Just out of interest, what sprocket teeth numbers did you go with - did you stay stock 17/40, or change them ?

I bumped up to 41 teeth in the rear - I doubt it will make much of a difference.

Speaking of rear sprocket... two of the rear sprocket nuts were completely round  :dash2: very fun to deal with...

good news: wheels are off the bike to get swapped - forks are off to get rebuilt. Before they go back I'll be placing all the new lines in there.

Instead of looking for 6th gear, he'll be looking for 7th!

The bike looks great!

It mighttttt have been possible I ordered the wrong size on accident. Lets just pretend I did it on purpose  :yes: not my brightest moment.

I cant see it making that much of a difference - maybe 5 mph more? If it feels really sluggish it will be the first to go.

also on the fun side: when swapping the grips out - the internal keying for the bar end was also rounded out (thanks previous owner) a ratchet strap did the trick and a new set is in the mail. 

so it turns out basically all motorcycle shops in the region are about 2 months out to change tires - which leaves me on my own for swapping them out.

Cant be too hard... right?

No worries....You'll be fine with the 17/41 combo....my '84 came stock with a 17/42 set.

Do not go cheap on your chain. Get the best of the best. A bit more $$ at the start but cheaper in the long run.

FJ's eat cheap chains for breakfast.

Completely agree - you trust your life to these machines, part failure mid corner can lead to a good case of the nasties.

I ran with a EK SRX2 chain from revzilla - I've had luck with EK chains before and it fits in nice on the sprockets (at least while its off the bike)

I've been doing it for years.  I bought a little balancer years ago also.  I've taught my kid how to do it.

A quick view of my balancer:

My teenager changing his own tyres:


I suspect your sprocket choice will be fine.  It will give you slightly lower gearing so that should improve the acceleration a bit.  You may be RPM limited to 146 MPH or so.

Yeah, believe it or not, not EVERYONE on this site is looking for FJR-like touring RPMs!
