Nice, now we need a pic with them on.

and a review of them and the install

The only hard part of the install was getting the old chain off.

Everything else was easy.

Take off the rear wheel
Take off the fairings on chain side
Take off the coolant reservoir
Take off the front sprocket cover
Take off the front sprocket
Take off the rear sprocket
Take off the chain

Reverse to install

So what is the advantage of the new chain and sprocket? Just replacing old and worn out or performance?

So what is the advantage of the new chain and sprocket? Just replacing old and worn out or performance?

Performance

There are two major advantages of the set up I used

1) Different size aprockets.

I went with a two tooth larger sprocket in back and a one tooth smaller in the front.

This changes the gearing what it does (Ill try to explain it in the most non-confusing way I can) is slows the wheel down relative to the RPMs the bike is at. This means that in order for the bike to go the same speed as a bike with stock gearing, my bike must be at higher RPMs. Higher RPMs mean more power, so my bike puts more power to the ground at a given speed. This makes acceleration faster

2) 520 chain is narrower than the stock 532 chain. This means less metal which means less unsprung (below the shock) weight. Meaning that it takes less effort to get the wheel to move faster than it already is (asccelerate).

I hope this helps. Sometimes I know what Im trying to say, but it is hard to put it inot words (especially when Its Saturday night and Im PWD :mrgreen: )

but also with this setup you lose a little top end. not much but some.

they look good. hope you like em. :cheers

So How did it Test Drive??? I was gonna go 2 teeth bigger on the back and leave the same amount in the front.

It rides very different

Pulls much harder through the powerband, but it requires more work by the rider. You have to shift a lot more often as you change speeds.

Worth it

The most "bang for the buck" mod there is (I think)

Ok...here's my question...and yes Im sure its been asked countless times before. I want to do the 520 conversion as well...as I want to be able to pull wheelies alot easier than now. My bike is a '99. I think Im going with a 15/48 combo..but here's the kicker.

Yes of course I know I will lose top end....which is no biggie cause I dont race. It seems like the more the gearing ratio is changed the more off the speedo is. (lol duh) I dont want to go too an extreme change in the gearing cause Im hopeing with just a few performance mods (K&N filter, Ivans jet kit and Blueflame slip on) I will more power delivery on the bottom end then not have to make such an etreme change in the gearing. Basically....has anyone tried something similar to this setup and if so what was the sprocket ratio you used?

It will be easier with -1 in the front either way. The mods you mention on top of gearing will slightly help as long as you get it tuned right.

The one down in the front will throw the speedo off quit a bit. YOu can get a speedo healer, or a yellow box to cure that. Speedo $68 or Yellow $110


A friend of mine has a '00 with -1 in the front and likes it. He clutches his wheelies, but can easily do them in 3rd and 4th

And also its easier to wheelie right? I have a '99 that I also want to do a conversion on. I believe you got a DID chain..but what brand of sprockets?

DID chain, yes

Sprockets are by Sprocket Specialties

Steel 15 tooth front

Titan Tough anodized aluminum 50 tooth rear

I am very happy with all parts

Ok..one..where can I get this speedo or healer thingy's? 2. Performance wise what would happen if I just dropped a tooth in the rear and stayed 16 on the front sprocket? I just wonder if its worth losing more top end changing the front sprocket as well.

It seems odd one would go down in the front (lol no not that way) and also go up in the back....such as that 520 15/50 mentioned earlier.

Basically..assuming I went to a 15 up front...whats the difference from going up 2 teeth vs down 2 teeth in the rear sprocket?

thanks again...

1 dn in the front in worth so like 4dn in the back I believe so if you go up with the back by 2 teeth, the gearing change isn't that radical. I will probably stand corrected on this though........

Unfortunately, my friend, I must be the one to correct you.

dn in front = up in back

1 dn in the front = well it depends on what you are starting with

On our wonderful R6s, we are starting with 16 teeth in the front and 48 teth in the back

This produces a gear ratio of 3.000 (48/16=3.000) (higher ratio translates into more power down low, reduced top end, and a ****ed up speedo)

SO,

ONE TOOTH DN IN FRONT (15f, 48r)

48/15=3.200

This is gonna give you a HELL OF A LOT MORE POWER

ONE TOOTH DN IN BK (16f, 47r)

47/16=2.938

This will give you a few more mph top end but will REDUCE your low end power (R6s dont have enough to spare so I dont recommend dropping teeth in the back)

If you continue to do the math, you will find that dropping one tooth in back is equivalent to adding 3.2 teeth to the rear (adding 3 teeth in the rear with the same front is gonna give you a longer chain too, by the way)

The OPTIMAL (in the mind of JASON) would be to drop a tooth in front and add two in the back.

This produces a gear ratio of 3.333

LOTS of power down low same length chain l

Top speed is down a bit but not so much you would notice and your speedo is ****ed

hope this helps

atleast I got the speedo healer thingy right.........

so basicly u screwed up everything else. not bad penfold. :mrgreen: :mrgreen:

What can I say? I'm mexicant! :moon

I was reading up again on your gearing equations on different tooth configs....Im thinking about the 15/50..and I believe Im gonna go with it. But I was curious on what your coments on a 16/50 would be...how much of a difference in performance this would achieve and if it would still warrant a speedohealer?

Well, to be honest with you, your speedo comes wrong from the factory...

Difference btween 15/50 and 16/50

well...

stock is 16/48

gear ratio of 3.000

16/50

gear ratio of 3.125

15/50

gear ratio of 3.333

16/50 is a big step up from stock, but 15/50 is a HUGE step up from stock. Your speedo will be off either way, BUT remember 15/50 makes the bike a lot more difficult to ride especially around town

Jason's tip of the day:

If you get new both sprockets and chain, buy the new stuff in the 520 size, it is a lighter chain and lowers the weight of the rotatiion, also, if you get a quality chain (DID gold) it will be pleanty strong for your R6

Ok..so if I go with a 16/50 setup ..I will get more punch in the low end..butnot as much as the 15/50. I dont want the bike to be too hard to manage. Im just looking for a lil more kick on the bottm end thats all.

You will be very happy going two teeth up on yer rear sprocket. Keep in mind that you may need a longer chain. Also, if you DO need to buy a longer chain, I would suggest buying a 520 chain. This will require you to buy 520 sprockets too (which means you will have to buy a 16 tooth 520 front sprocket as well).

It is a good idea anyway to do the sprockets and chain at the same time.

Ya I was gonna go with the change up front regardless...just didnt know if I was gonna change the tooth size on it. Im gonna try the 520 16/50 set/up on my '99 Hopefully with that BF exhaust and K&N filter/Ivans jet kit it'll give me all teh low in kick I need. I wonder howmuch longer a DID chain Im gonna need. Also...any comments on teh SS series at Spocket Specialist?

Thanks again.
:comp

You will like 16/50 w a 520 chain

DID chains come in 120 link lengths, just put the whole thing together put it on and cut it to length...

What brand of chain and sproket do y'all recommend? Does it make a difference?

DID

Just did the 520 conversion. 1 down in the front. Afram front and rear sprockets with a did x-ring chain. The thing kicks ass, you can feel the back wheel pushing you hard. and some how the power feels smoother all the way up to redline.

see i know something after all :mrgreen:

Well, I got around 12,000+ miles from the stock chain and SS sprockets. I just got my 520 conversion in the mail yesterday. RK GB520GXW chain and AFAM sprockets running a 15/48 combo. Still waiting on the RK Chain Tool so I can put them on :cheers
