38 / 18 sprockets

[Sabre093]

I went with 18/38 combo and I love it,worth the money for sure I had to change sprockets,17/39 in 5th I was doing 3800 rpm now I'm doing 3300

   That is the most worn sprocket I have ever seen that was still intact [no broken teeth].

Yes, it looks like he got his moneys worth.

I stand corrected.

 Baaaa, that bike just needs to have it's chain tightened....many miles left on that sprocket.

Pat, I thought the same thing when I saw that...... Tighten up the chain and stay up one gear too high and clean off any chain lube....

Finally fitted the chain, someone on the UK FJ site kindly lent me one. Well, I do have three other bikes to ride.

Now, I'm waiting for my mate to cut up a couple of pieces of metal so that I can mount the rear indicators. I removed and sold the Non Fango panniers and topbox, my other bikes can all take luggage, so I didn't really need it. Waiting for the rear side panels I just sourced from E bay, then get it MOT'd and we're up and running.  

Big bonus as well, I paid £500 for the FJ, sold the luggage for £150

At the start of the year I had ten panniers and top boxes, now down to three. Garage is much tidier, still overcrowded though.

I have a 38t sprocket on the rear and currently have no idea what the front sprocket is. Around town I have had no issues with difficulty with the gearing. I have not had it on the super slab yet. I have a 18t counter sprocket waiting for me to install when I get the bike back from the head rebuild.

I reckon 18/38 takes nothing away from the abilities of the FJ. Acceleration is still arm stretching, cruisability is wonderful, its a win win. If you like winning drags from the lights over 50 metres then its not for you, but anything longer and its game on!

On the motorway in 5th at 80mph, I dropped into 4th, dropped into 3rd, then dropped into 2nd  Think this was about 8,000 rpm. Bloody hell. I haven't ridden it since August, even with the higher gearing I was still surprised how quick it is.

I've got 17/40 and it's ok. It's what came on my fj when I bought it. I will probably go 18/38 next and try it out

I have a 18/38 with 530, 110 links. Sits about 3/4 way back. Probably could have went to 109 links BUT I wanted to have a little slack so if I want to install a larger rear sprocket it will probably fit.
In short 18/38 is fine with 110 links .  I think that I read 2 or 3 teeth on the rear equals one tooth on the front.

A change of 1 tooth on the front sprocket equals ~3 teeth on the rear sprocket in RATIO.   
Diameter of sprockets (for a given chain pitch) determines diameter of the sprocket and therefore chain length needed with axle in Xposition.
You won't be able to go to 109 links on the chain unless you can find a "1/2 link".  I haven't seen one of those in many years. So, you'll have a choice of 110, 112, 108 etc. and will have to adjust axle position to suit, if you can.
So endith the lesson. :-)
