Time For A Gearing Change ?
#21
Posted 17 July 2018 - 08:35 pm
Just been out to test it (about 15 milles) on a mixture of town, B roads and some A roads.
In my opinion the bike is much more useable. I can use 4th gear down to 30 before changing to 3rd.
To sumerise I found myself changing gear a lot less on this brief test ride.

If you're wanting to check your speed exactly, most local authorities have (or certainly did have) a measured mile. Speed = distance / time. I've never found sat navs to be that accurate. Or find a friendly speed plod to check with the speed gun. These are supposed to be accurately calibrated.

I fitted a HealTech Speedo Healer to mine and from memory the Healtech App calculated a 5.2% variance for the standard 16-42 gearing. Switching to a smaller front sprocket increases the inaccuracy even more, will be more like 8% off. Going the opposite way (17t front sprocket) blunts the acceleration but would make the speedo almost accurate.

For anyone interested, I fitted the 15 tooth front sprocket today.
Just been out to test it (about 15 milles) on a mixture of town, B roads and some A roads.
In my opinion the bike is much more useable. I can use 4th gear down to 30 before changing to 3rd.

I found - 1 tooth to smooth out any jerkiness, and consumption only increased marginally
900 with better bits. Owes me nothing, Makes me smile

update: see here the page: https://www.tdm-yama...t.org/?page=RATwith a awesome great range -front sprocked from 13 to 19 teeth and besides thatrear sprocket from 34 to 50 teeththis is overwhelmingly big
What has prompted you to look for a gearing change ?

good day dear fixitsan
many thanks for the reply great to hear form you
well i ride also a Suzuki VX 800 _ with
5 gears and cardan - so far less options to do any thing in that direction
but the VX has got power enougth for a different gearing - to lower the rpms

and of course: https://www.volusiar...800-c50.185987/and - besides that i have had a Suzuki GS 500 - where i wanted to do the same - lowering the rpmsAdding a Tooth -- Going Up to a 17T Front Sprocketso - i think the TDM is pretty good for thinking about these matters (too)i wonder _ which front sprockets fit on the TDM; 900and which rear sprocekts _stock is 16 / 43 isn ´t it !`?

good day dear Fixitsan
many thanks for the reply - i did not get it - you link to exactly this (!!) thread
look forward to a fruitful discussion of all things gearing and gearing ratio
perhaps we can discuss all that things with regard of this great page
https://www.tdm-yama...t.org/?page=RAT
Interesting topics
what options do we have to change the gearing ratio
Tires
sprockets - size - and adresses where to obtain!?
and all that things.

I was just trying to point back out to you that you already have the ratio information, now all that's required is for you to try them
Without knowing your main use it's just guesswork. Dropping one tooth at the front, for example, gave me higher revs at lower speed, something which makes the bike more comfortable and easier to ride slowly in first gear. Sometimes I go up steep inclines and tall gearing doesn't suit it that much

hello dear Spike240
many thanks for the reply and for sharing all your thougths - this is a great idea.
Hi and thanks. There is a link earlier in the thread to a site gearingcommander which is very very good. It does all the maths for you, but there's nothing like experiencing the change - if you know what I mean. Can't help thinking if a 15 tooth sprocket was better than standard 16 then Yamaha would have done it. Having said that, my mate (mentioned earlier) is a dinosaur biker/racer/mechanic and reckons for the losses on top speed the bike will be more useable.
So for the cost of a sprocket I will try it (don't know when tho). When I have done it, and road-tested it I will be sure to let you know.

well i also like gearingcommander.
its is backed up with tons of data - very nice.
i look forward to hear from you - i love to see a fruitful discussion of all the thigns that are possible
have a great day
greetings
