It's time for a new chain - the cheapo one I stuck on the old sprockets 3 years ago is approaching end of life.
So, I'm toying with the idea of putting a larger sprocket on the front. :eek
I'm not interested in pulling wheelies or riding like a dick, I more interested in MPG's on the way too and from work so the loss of accelleration isn't a problem.
Anyone tried anything like this before? How much difference will it make to the ride/MPG etc?
-
Would there be any clearance problems inside the cover? I'm thinking a smaller rear sprocket would have the same effect.
-
AFAIK you can get away with one or two more teeth on the front.
On tooth on the front is the equivelent of about 3 on the back - hence why I was thinking of doing that rather than changing the rear.
-
Ahh gotcha! I'm thinking about doing the same as I do a lot of motorway miles. Sounds like the front is the way to go. :)
-
Have a look at http://www.gearingcommander.com/ (http://www.gearingcommander.com/) you can play about with the ratios and see what the effect on the speed, rpm at speed the change will have

thats handy - there was one on the old fazer site.
Gonna go for front +1 and rear -1
See how that goes, it it's too much I'll swap one for a standard.
If I put the back on the front and front on the back I can do 500MPH in 4th :rollin
-
I went 1 down on the front and 1 up on the rear. It makes quite a difference. My riding style is obviously the polar opposite of yours, as I love to ping it about and care not for MPG and motorways. If I have to use the motorway, I'll take the SAAB. But my point is, one tooth at the front either way will make a noticeable difference. If that is done with a change at the rear, it will make a significant difference.
-
I tried one tooth up on the front, it was very noticeable, sluggish, forever changing down gear to overtake, fuel comsumption INCREASED, I stuck with it for about 3k miles and then put the CORRECT sprocket back on, Aaahhh Lovely
-
Come to think of it, I've still got the bigger sprocket which you are very welcome to. It's only done 3k, try it on your old chain before you go out and spend money. PM me your address and I will pop it in the post, Fraser

Good egg!
There be a good egg! 8)

what a luverly site this is!

That Gearing Commander site is a tad innacurrate: On stock gearing, it claims a 600 will do 230mph in 6th at the redline. I suspect it isn't taking power into consideration here (or rolling drag, or friction, or aerodynamics.... :lol :lol ), as a bike can only go as fast as its engine permits.
-
That's not a basis of Gearing Commander being inaccurate. The 600 would do 230mph in 6th at the redline... if it had the power to do so
The purpose is to show the gearing ratios and related speeds, not to debate the finer points of whether these speeds are possible or in what time they would be achieved
-
True, but then the bike has to have the power to accelerate with the added load upon it.

I've relatively certain I had mine quite close to the red line about 11k ish) , at about an indicated 150?

I would imagine variations in the rolling diameter of the wheels and tyres will be the major factor there?

Apologies, you are correct and gearing commander puts 11,500 RPM in 6th as 143 MPH - Christo's data was wrong, which I didn't verify on the actual site. The dozy muppet was reading KPH not MPH :P
-
well i got the chain and sprockets today, +1 front , -1 rear so will fit them sometime in the next few months (wanna eek out the best I can from the current chain) although I don't think the current one will last long now - time between large adjustments (1/2 turn) is down to 3 weeks.
When I start using them I'll post back and let you all know the results. My mpg is consistent at 50 (+- 2) mpg so will see how the fuel consumption is affected.

The dozy muppet
Not the first time that's been said :rollin :rollin

I've been known to do it myself on occasion! :lol
-
I went +2 on the front and -2 on the back.
Still love riding the thing!
plus I get 260 out of a tank. And that was before i fixed the monumental hole in my downpipes. haven't run through a whole tank yet to see the difference.

I still have no idea how you can ride like that chap, pulling away must be bloody nightmare, and I can't imagine how slow it would accelerate! Cruising speed on a motorway would be like 3k revs!

Check a few of my youtube efforts out Joe. I know it's not like riding it yourself, but you can kinda see that it still goes!

And it's doing about 4000 rpm at 60, ( i think, haven't ridden of for a couple of weeks!)
-
According to Gearing Commander that would be accurate and I can't see it being a particularly huge difference for cruising - the 1000 at stock does 60mph at 4000 rpm
The lower gears will be more noticeable, but if you are just commuting you are still going to be able to pull away from lights / stops faster than cars can :)
-
It probably wouldn't be dissimilar to my restricted bike, but rather better!

Way better

They're on. Front sprocket nut was loose (despite having the lock tab still firmly in place), but no surprise there.
Went for a short test drive to Tesco and back (under 1/2 mile) and seemed fine to me, not a lot of difference.
Will see what it's like Monday when I do the work run - got a 4 mile motorway sprint.

So, how did it go?

Was gonna post when I had some fuel figures.
It seems good - the main differences are when pulling away and at the top end - It's like pulling away in gear 1.5 instead of 1st and having a 7th gear available at the top. I find it suits my riding perfectly - most of which is in town and filtering then on the motorway. The power is still there, you just need to change down a gear (or stay in the lower gear a fraction longer) to bring the revs up a bit. When filtering the engine isn't as torque-y - which is a bonus for fine control. Wish I had done this years ago.
Will post back when I know how the fuel consumption works out.

NECRO - rise from the dead thread!
Thought I'd bring this one back and post a final update.
The Fazer will be part-ex in under a week so this is the final update on the long gearing.
Overall it worked out well. The mpg increased a little: I used to get about 150 miles to a tank and now I get about 165. The power has dropped obviously, but if you stay in a lower gear you can still enter warp speed when the rev's hit 7k although it's not quite as fierce as it used to be. So for commuting that makes no difference at all. I found with the long gearing it was easier to ride in traffic and low gears were not as torquey. Mind you this suits my style of riding - in traffic I tend to ride with low revs and use the engine torque.
I can't say if this would have improved tyre life as it's not been long enough.
So. Thats that. I'm glad I did it and would do again.

Nice one mate, it's good to see a thread followed through. Good luck and enjoy whatever you get next.

I like the sound of this

It wasn't until i got to this post that I realised it was old.
Well done for coming back with your long term report, so often i am reading old posts for a problem and the poster has not come back with the results of the help
-
My girlfriend has two extra teeth at the front,,man !!!! she ain't pretty :o
-
but do you get more miles per gallon out of her? :rollin
-
Not really noticed , but she smokes alot, could this be the reason? :lol
-
yep - bores enlarged and needs oversize pistion... :eek :rollin
