Title: GSXR back rim.
Post by: Paul.1478 on November 05, 2018, 11:11:59 AM
Hello,
I have a 93 FJ1200
It is time for new tires on the FJ and as I have seen posted several times and noticed when looking for tires, they choices are very limited with the 16" back rim.
So I was hoping someone has a 17" wheel setup with all the needed parts sitting around they want to get rid of. I have no machine stop or real desire to fabricate anything so hoping for the GXSR rim, chrush drive master cylinder and brake caliper ect

thanks

Get the '91 GSXR wheel. No machining of any kind is necessary. Try to find the entire wheel, with disc, caliper, torque arm, spacers, bearings, etc.

Try this

Thanks for the reply and link! .
I looked and did not see this.

I sent a message to the seller asking if they have the rest of this.

It will need to be painted but small detail.

Check the pdf file attached to the first post in this thread for some good instructions. You'll need several large fender washers for spacers.

well I went with a new set of tires and was going to put this on the back burner. After I got them, woodcreekpete in Canada contacted me with a GSXR wheel with spacers, modified caliper mount and all the parts to make this work.
SO... Parts found...
Thank you all.

You're gonna LOVE it!  Take a look at fabricating some new dog bones to get the ass up in the air a tad. Go with 115mm center-to-center length. It makes a wonderful difference in turn-in handling.

I will have to look into this. Thank you for the tip. any help with handling I love. going straight is not for me.
And while I am at it, what about rear sprocket? with the 17" what sprocket would bring it to about stock?

The 16 & 17" work out to be much the same OD, certainly for the sake of gearing.

I use Gearing Commander (link below) Paul, it's a great tool for looking at the effect of sprocket changes and wheel/tyre changes  on a huge range of bikes - especially useful for seeing the rpm/speed impact of sprocket swaps on the FJ, which can carry much taller gearing for more relaxed high speed cruising.

My combination of 170/60 x 17 tyre, reduces the wheel circumference very slightly, but I'm running 18:38 sprockets. This means I'm running 4000 rpm at about 72-73 mph - just right for our motorways/ main roads - and it doesn't make the bike struggle in first gear on pulling away.

I love that. what a simply site. It will make choosing gearing super easy and really like you combo. 91 mph at 5K. just about right...
I do tend to shift into 5th about 2-3 times... feels like it needs a 6th.

Get the 18 tooth front sprocket from RPM, and match it to a 40 tooth rear. Perfect.

Also, look up my gear indicator mod (http://www.fjowners.com/index.php?topic=17615.0). It'll keep you from trying to find 6th...

I also use the 18t/38t sprocket combo. The rear sprocket is noticeably smaller than the OEM 40t sprocket. I like the fact that the engine RPM's are below 5000rpm at Highway speeds. Never had any issues with pulling away from a stop. With the sprocket change and reduction in RPM's, I have found the instances of searching for 6th gear has been greatly diminished.

The shift indicator is a brilliant mod. Love it. The idea of using the tack is great.

Jeff told me to go to Rebel Gears to get a sprocket if I wanted one less than 42 tooth.
I emailed them the year of the rim part number of the stock one and the tooth count I was looking for.
Before I got home they called and said no problem. 62.00 and take 2 days. Wow great service and shockingly easy.

This should be easy winter project for me.
Thank to everyone.

Paul,

If you go for a 41 tooth rear sprocket, the bike will be revving higher than standard at any given road speed. This seems the opposite of what you were wanting to do ?

Is that $62 for the sprocket ? - Seems expensive compared to what we pay here.

The stock gearing on my 84 was 17 and 41. I changed to 18 and 40. It made slightly more than a 500 rpm difference at highway speed. Most of the guys that do a lot of highway riding go to a 18 and 39. Pat was running 18 and 40 on his 84 with the 17 inch rear tire mod. Riding beside him our speed and rpms where the same as the 17 inch tire has about the same profile as the 16 inch stock. 17 just gives you a wider selection of rubber with a wider tire.

I do not want the 42 that's the issue.
89 gsxr 750 (the rim I will have )  smallert soroket is 42. I have to have one made.
Agree 62 is high compared to off the shelf but not bad for "custom" made.

Post by: Millietant on November 15, 2018, 09:15:08 AM
That's cool Paul, I understand re the cost  :smile:

I was just thinking that as standard is 40 teeth on the rear, anything more than that on your GSXR wheel will mean that your bike is revving higher than standard (and if you went for the 18 tooth front, the 41 rear will be negating some of the benefit of the front change)   :good2:

I found a 40T GSXR sprocket on eBay.

The 750 wheel has a 5 bolt sprocket not the 6 bolt like yours Rick. The 6 bolt sprocket will not fit.

Well, that's just stupid. Will the cush drive with six bolts fit the 750 hub?

Post by: RPM - Robert on November 15, 2018, 11:08:23 AM
That I do not know. I actually thought they were all the same yesterday until Paul contacted me and said our sprocket would not work. Upon further investigation, our supplier only stocks 42T-48T sprockets for the 1989 GSXR750.

Guess he could ride wheelies everywhere if he wanted a cheaper sprocket.

I've got an 88 gsxr 1100 4.5in wheel that's got the six stud sprocket fitted. Strange how they went smaller for the 750 as it wouldn't exactly be lacking in power itself. Not sure if the Sprocket drive is interchangeable, I'm assuming it is and might be something to look out for as smaller sprockets are easily available for the six stud. I found a 38t sprocket for mine on EBay no problem at all.

An 18t/42t is not a bad combo. That would at least get Paul on the road until a custom sprocket can be made.
Title: Re: GSXR back rim.
Post by: Millietant on November 15, 2018, 03:24:51 PM
True Pat, I agree.

18:42 is as near as makes no difference to the stock 17:40 sprockets.

It only 4 days from order to delivery.
I'm not going to do it for a few months. I just got new tires installed.
Need to burn off the back ASAP.

Thank again guys. Great helpful group.

 My 84 fj1100 came with 17/42 sprockets and i still have those sizes on.I do admit I try to shift to sixth often on open roads but I've yet to top it out in fifth and i love the gearing when driving sporty through the mountains or when passing.I've never ridden another fj so I don't know what I,m missing.

Post by: Pat Conlon on November 15, 2018, 07:27:43 PM
Hey Travis, yea, same here, I remember the 17/42 combo on my bike. That was a looong time ago.
The easiest way I have found to experiment on my '84, is to try a 18t counter shaft sprocket. See if you like it (you will) Your chain will like it for sure.

Changing the front sprocket is a snap, much easier (and cheaper) than the back sprocket.

Just before my big trip with Cap'n Ron this past summer, I installed brand new chain and sprockets. I went with 18/38
After riding that whole trip with those (6,000+miles) I am switching back to 18/40..............I may even try to find a 41, if anybody makes one?

The 18/38 combo is too tall for my liking. The FJ has no trouble pulling away from stops with these, and has plenty of torque to accelerate with them even in the higher gears.
Although I liked how this combo put the revs down in a lower range, I felt that it caused the engine to be "working" slightly harder during the kind of riding I like to do.
I noticed my fuel mileage to be slightly worse than with the 18/40 combo, due to me having to use a bit more throttle to maintain speeds, either on the Interstate, or into the wind.................especially loaded with gear.  I feel that it puts the revs below the "sweet-spot"

Anyway, that's just my findings. YMMV  :drinks:

ps:  I'll probably have a slightly-used (only just over 6,000 miles) 38-tooth rear sprocket for sale shortly.............

I switched to 18/41 about 80,000km ago. It was one of those changes that I never gave another moments thought to, it was just right. As many here know, my riding covers a bit of everything from crawling along bush tracks in first gear to big, fast days and everything in between.

I can't imagine going a whisker either way being an improvement as an allrounder best option.

There is however no right or wrong with gearing, within reason it is entirely personal choice.
