Hi all.
I don't know if it is of interest to anyone.
I've found a company that stock 19 tooth front sprocket for our 14's. I've been running one for 2 years now, no problems! 9000 miles. (It also puts the speedo reading spot on.)
They are German based company.

I'm bad at maths - this lowers or increases the gearing? Some more acceleration, or lower revs at top end ?

Lower revs at top end. Perfect gearing as far as I'm concerned. I've done well over 100,000km with either 19/41 or 18/38 and would never go back to stock.

When the time comes for new sprockets and chain, I think I'm going to try this. Properly 19/41.   :cheers:  I generally just chug along.
Doesn't hurt to experiment.  :onya:

Perhaps you, or someone, would be kind enough to write a brief article / few paragraphs explaining gearing and the effects of changing Front sprockets , rear sprockets etc in overall gearing / what it means in the real world.

eg standard (whatever that is, perhaps 18/41? Not sure) so where does 9/41 and 18/38 sit on the spectrum.


Q for all - Who prefers lower gearing? Higher gearing ?

Good find Nellywelly, I've been looking for one of them for a while now, I will get one when my chainset needs replacing.  :onya:

In theory the gsx 1400 will do 85mph @ 4000rpm on standard sprockets (41/18).  Going up to a 19 front sprocket (41/19) will give an increase in top speed to 89.7 at the same revs and going to 38 rear sprocket (38/18) will give a speed of 91.7 at the same revs.  However the smaller rear will probably need a shorter chain so if you don't like it, it will be difficult to go back.  both these changes will most likely give you a more accurate speedo reading.  Changing both sprockets to 38/19 will give you a theoretical speed of 96.8mph @ 4000 rpm and you might get away with the standard chain but I think it will be at the extreme end of adjustment (my thoughts only).  If the bike will pull some of these ratios the speed at max power (6800rpm) would be:-
41/18  =  144.6mph
38/18  =  156.0mph
41/19  =  152.7mph
38/19  =  164.7mph

18/41 is standard sprocket setup.   

I have the black with std sprockets & the blue with 17/41 (lower gearing)  Which do I prefer?  can't make up my mind TBH.  I don't (as a rule) go as far as possible in the rev range through the gears or when touring, I do however like a quick acceleration & the blue with the 17 front has that over the black for sure. Touring or cruising, yes I'd be running more revs on the blue than the black, does it matter? or make much difference? Not that I've noticed really. Fuel consumption is about the same or slightly better on the blue - figure that? 

I had also been thinking of a 19 front, but reckon going from a 17 to a 19, the bike would feel 'dead' till I got used to it.  Might just get one though and it's there if ever I want to play around with it.

I forgot to add this link - great to see what a change will do without doing it for real.

I am happy with the standard except for 1st gear where I would like a bit higher ratio.

If my el cheapo EK ever wears out ill replace full kit with 19 front. EK chain and JT sprockets my choice. Not sure ill like higher gearing but think i will. Have used many other chain brands , EK just seems to work best. http://www.ekchain.jp/product/#

I should set you straight on the 38T rear sprocket. I doubt very much you'll get one to fit a 14 unless you do what I had to do.

How many of you look for that 7th gear? I used to do it constantly so I decided some taller gearing was required. At the time I searched for a 19T front sprocket but there was nothing available so I bought a couple of blank 38T and machined them. A blank sprocket for those who don't know is just a disc with the teeth of course and a small centre hole for hobbing. They have to be drilled and bored out to suit the sprocket carrier.

A bloody lot of work and unnecessary if a 19T is available. BTW, I still look for that illusive 7th gear but not very often now.

Useful knowledge, so I've moved to Chains and Sprockets and stickied it so its easier to find in future :onya:

I run with 19/41 it works with standard chain length. I also have a 190/55 rear tyre. (I just like the way it rides with 55 profile.)
I find in full touring setup (top box, panniers, tank bag and 2 up) it still pulls like a train.
Cruising is much nicer too. Not looking for that non existent extra gear. And it still pulls well in top gear. I have a T,R,E, fitted to. That makes a difference to through the lower gears.

Nellywelly, great feed back mate. Just what I like to hear regarding options others have tried.  :onya:

Only difference is my tyre is 180/55. And I do enjoy the open road for a ride in the country (getting through the traffic in the city to get there is the challenge some days).

I tried the German site to order, just not working. What am i doing wrong? I dont understand German, translator not helping. Anyone else bought a 19t front.

@grog  No idea what you are doing wrong, if any. Got cookies and java script enabled? Did you Right-click and translate to English? Might help if you post a screenshot from where you get stuck.

Thanks, I'm up for new tyres, and I suspect new sprockets and chain (40,000km on the bike and I've not changed them since I've owned it from 30000km, I will prob follow the 190/55 rear tyre and 19/41 sprocket route

Supplier can be contacted in english language AS they confirmed to me. Info(at)kettenmax.de

I've ordered 2x 19t front sprockets from them this week. 1st time I tried it didn't work properly, it wouldn't process payment.
2nd time it went through no problem.
I did notice afterwards the 1st time I tried postage had not been added. I don't know if that could be the problem.

Try opening it using Google Chrome grog, just tried it and it comes up straight away in English

Thanks blokes. Chrome makes it easy, good shop, lots of stuff. I just found 19t Esjot in Australia. Metal Gear in Brisbane for $22. Also a good shop.

I just saw this also.
Brendale, not far, race you there!  :onya:

I've been after a 19T front sprocket for ages now without success.. I'll be sorting this when I get home from Cornwall next weekend :onya:

For those that are interested I use this site to work out custom gearing changes..

https://www.gearingcommander.com/

The first shot is with standard gearing and the second is with a 19T front sprocket.
In theory a 19T front should raise top speed in 6th gear at 6800 rpm from 144.1mph to 152.1mph. A gain of 8mph if top speed is your thing :onya:

Apart from the top speed gains that most can't use anyway .this should improve fuel economy a bit as it will reduce the revs at cruising speeds.
The bike will feel sluggish low down but as I noticed when I went from the 17 tooth front to std 18 it felt sluggish but soon for used to it .
I'd be interested in seeing a picture of the bike with the 19tooth front sprocket to see clearances ECT.

:cheers:

There you go Seth

Thanks for the pic @Snapey .
It looks like there is plenty of clearance. When you go up a tooth on the Bandit you have to shave a bit off the sprocket cover otherwise it jams the sprocket!

I've just ordered two of them :onya:

Thanks
@Snapey very useful
As said plenty of clearance there . :onya:
I look forward to your thoughts @froudy when you change to the bigger sprocket.  :cheers:

Should use the spreadsheet on here Steve, feeds the variables in for the 14

I went up a tooth on the front on both my Bandit 600's. No noticeable lack of acceleration and made it a far nicer ride..A bit faster too on top end.

I'll report back once I fit mine. If I don't like it then there will be 2x19T front sprockets for sale :onya:

Snapey, the same as me. See attached photo to compare sprockets. Something interesting, odd sprocket weighed 355g new weighs 423g. Looks like I'm going on a diet.

Froudy, I used gearcommander.com as well and interestingly I have 180/55 tyres to use in comparison to sprocket teeth number. All in all, looking to smooth out my necessary gear changing lengths, tha's all.  :onya:

Downside is my 'Speed Sensor Rotor' and hex bolt refused to come off. Murphy's Law. Destroyed the sensor rotor but eventually got the sucker off. Seems the previous drongo may have put this bolt on at 115 Nm and the spindle nut behind on at 20 Nm (spindle nut basic fell off with little effect).
So $22 for the sprocket, $25 now for a new speed sensor rotor, a new 6mm hex bolt to attach it, and a few pennies in the swear jar.  :cheers:

When you say hex bolt are you talking about the socket screw?

Do yourself a favour & buy a rattle gun. Electric or air it probably doesn't matter but for sprockets & forks they're perfect.

It's the round bolt that takes a 6mm Allen-key (hex) that fixes the speed sensor rotor to the drive shaft. Not the 32mm nut that fixes the sprocket to the drive shaft.

Impact wrench is already in the mail. Expect it early July. Link below shows it. Not too expensive but not too cheap (staying clear of flea bay no-name brands or one's with strange Asian name types).

https://www.amazon.com/Impact-Wrench-Campbell-Hausfeld-TL140200AV/dp/B006JVIHQI/ref=sr_1_8?crid=3S4OTGGJ5XVHO&currency=AUD&keywords=air%20impact%20wrench%201%2F2&qid=1561177075&s=gateway&sprefix=air%20impact%20wren%2Caps%2C385&sr=8-8

I thought that was it but I thought a previous owner must have replaced it with a hex bolt. It's proper title is socket head cap screw but some people might call it an Allen screw. There are even some who call it a hex bolt. :whistling:1

Did I just get dumped on regarding a bolt, sorry a socket head cap screw. Didn't my previous picture illustrate the bolt, sorry socket head cap screw.

I'm tempted to go with a 17 front (or perhaps a few more teeth on the rear) though the former is probably easier / cheaper

No issues with the chain rubbing on the sprocket carrier or anything else?   (I know it's an issue on the DR650 which is why I ask).

@VladTepes No, no issues running a 17 front, still 116 links, just back a tad further on the rear adjuster. 

Just in case anyone is wondering what a 'tad' is, it's a technical expression of a precise measurement for 'a little bit'.

@KiwiCol
As in up in Scotland and we still measure things in bawhairs
Could you please supply the correct conversion for bawhairs to tad's
Thanks  :doh:

@seth Unfortunately there is no direct correlation or conversion from Tads to Bawhairs that I've been able to locate. My best guess is ask someone on the equator (as we're under & you're over) & see what they use, this may also give rise to another measurement again.    Math, funny thing isn't it.

We also measure in bee's dicks.

A bee's dick being 1/2 of 3/8 of fuck all.

Seth 1 tad = a smidging

Quote from: Daytona on Tuesday, 16 July  2019, 05:15 PM
Seth 1 tad = a smidging

1 Tad = 1 smidging.
1 Bawhair = 2 Tads or .5 of a bee dick.
1 Gnats whisker = .5 of a Bawhair

Oh, and I still haven't ridden my GSX14 since I fitted the 19t front sprocket..Played on the Bandit last week as it was MOT time for it.

Vlad, you beat me to those two.

Quick update..

Having been off from work for the last four weeks with "Family problems",  I finally got to ride with the 19t front sprocket fitted yesterday. Now this is really quite embarassing as it was only as I logged on here just now that I actually remembered that I'd fitted it. I hadn't ridden the bike for a month so it seemed fast anyway.
I had a bit of a "Play" with this 2 smoke Honda on the way home last night and I can report that the GSX14 went very well :devil:

Next time I ride it, I'll try and evaluate it a bit better :imrgreen:

Cheers for this.......only downside is the postage to the UK is more than the cost of the sprocket..Lol!!! Going to order one anyway and see if the speedo shows the correct reading now.....always within the speed limit officer.... ;)

If its correcting your speedo to read the right speed, then you might want to consider a Speedo Healer from Healtech instead @The Stumeister

I just always assumed the GSX speedo was a bit out as when i'm doing say 80 or 90 it doesn't feel like that speed..!!!

Other guys have done this evaluation previously & found the stock speedos vary in their inaccuracy, from 5-11% too fast, so a 19t front may fix one  bike, but not another.   

My GPS tells me when I'm speeding, problem is it never shut's up.
