My 2008 R6 -Sprocket question

[Zakk]

Hey guys I wanted to get a bit more acceleration from the little bike and was gunna get a new front sprocket. Is one tooth down on the front (I think stock is 15?) enough or would I need to go up on the back as well? What brand and material to be made out of, Is a 520 chain conversion worth while. Please be advised when you answer that I am Indian and mechanically minded as such Turtle Marky g and James can testify to this so break it down to Chimp talk. Thanks brothers:ayyy

1 down in the front will be plenty, If you do a 520 conversion you have to change both sprockets and chain, unless your riding 100% track its not worth it in my opinion as the materials used to save weight are a lot softer and therfore wear out quicker, a 15T 525 front sprocket can be sourced from MCA for about $20. try it first then see.

I just installed a Driven 520 conversion kit from Motomummy, shipped to my door in 4 days

Was there a significant difference?

There will be, but the biggest "problem" your bike is having with acceleration is the fueling being out. Not saying don't do the sprocket change, but the bike will drive way harder off turns etc once the fueling is right. I've done many a bike that was going to do the sprocket change first, but decided against it after it was fueled right. Just advice for anyone interested, that's all.

Both front and especially the rear were much lighter than my steel ones from chaingang. But riding no u don't notice the difference in weight.
I dropped -1 on the front and is a noticeable difference riding i had +2 on the rear prior to this.

Thanks Trev,

Im just tucking the shekels away for a PC and Mapping. But in the meantime i though this may be helpful:ayyy:

[Birdman45]

Jesus 848, you should be climbing trees with 2 up on the back and one down on the front. LOL Like I said, it will help, it has to, but it only masks the problem or the biggest part of it, that the bike isn't accelerating as fast as it should coz the fueling is out. You get that thing mapped, and you'd be hard pressed to keep the front wheel on the ground EVER with that sorta gearing. Hahaha

Nah no dramas Zak, just general info for anyone reading.

I'm just trying to get this straight in my head. Are you saying a stock bike with no modifications to the engine (including stock exhaust and stock airbox) is not fueled correctly?

If this is the case I assume this is caused by manufacturers trying to meet efficiency regulations retard the timing and lean the bike out. So advancing the timing and running the bike richer would fix this?

Just asking, not doubting what you are saying, just want to understand.

LOL i previously had +2 on my old set up, have now gone stock 43 rear and just -1 on the front.

[Lopeman]

i would not go any lower than 15t front, idealy a 16t. The tighter u make that chain turn the harder you work it. Generally find your chain and sprockets die quicker when the front drops below 16t. Go up in the rear 3t iinstead

[DanFX]

I had 15T on the front and 47T on the rear on my 08 for the street, was pretty cool down low
but 1 down at the front will be all ya need... stock is boring

Hey thanks guys - I feel alot more in the know now. Ill drop one on the front and get Trev to work his magic then Zeno. The R6 is a fucking awesome bike, to be honest dont need the litre bike. If anyone has any goodies for sale for 2008 R6 pm me.:ayyy:

[Birdman45]

I have a second hand Arata full system for it you can have for $800 if you can get it off Alex Tomassetti. LOL He borrowed it a year or so ago and I never got it back. Thinnk I have Matris dampers for it also on sale, yep I have. $600 for the M2 and $700 for the M3. But if you want one I will do better than that for ya.

Thanks brother this may sound naive but whose Alex Tomasetti(was he out of the Godfather?)

The full sysytem sounds great. Are the matris dampers as good as the Ohlins , Scotts or GPR? I know you would nt sell anything unless it was good shit anyway:ayyy:

[Birdman45]

Yep and they were the first to introduce the expansion chamber on the damper body to help with the expansion of the oil once hot etc. They work just as well and come with really nice mount kits, something which many of the others do not.. The Ohlins are good dampers but they can lock up due to how they work (tapered needle), the Matris runs oil through varying sized holes to control it's rate instead, so they won't lock up. And as you said, I don't sell anything I wouldn't use myself, or that doesn't work well. I ran these dampers, rear shock and front fork kits on my 600RR and loved them, awesome things.

Alex is just a club racer in the Oz supersport series and also works for Serco, (last I heard) I am trying to get hold of him now to get it back if you want it.

We used to run 14 / 43 at EC on the 08 R6 with the Dunlop 200 series Ntecs. This was great gearing for a large tyre and 1:34 lap times. A smaller tyre and different times will create a difference, but I would think a 180 tyre and 1:40 - 1:45s should work well with the same gearing. 520 is the go.

Hey Terry - thanks for the advice brother. I really apreciate this. i will try this combination as the R6 will be turned into a track bike early next year. do you think i should go 200 as well?

Hey brother once again thanks for organising the dna filter -Yes I will take the ARATA system from Don Tomassetti as stated on the phone. Cant wait for your deal you gunna do for the power comander and mapping?? AWESOME SERVICE :ayyy:

[Birdman45]

Hahaha ALEX Tomassetti. Still trying to get a hold of him though. Let you know.

[WET4URacing]

0438701354 will get him

[Birdman45]

yes but will it get my system back? haha
