Hello,

I do not yet have my 06 R6 but I was wondering why is there so much positive talk about the 520 conversion. Is it because it is a smaller and lighter set-up? Is there that much of a difference?

Anywhere in SF Bay Area that is recommended to do an Exhaust and Power Commander set-up. Would just bolting up the pipe offer poor performance or would it be sound only.

Or maybe a trip to Graves for the setup?

The idea behind the 520 conversion is reduced rotating mass. First the 520 chain and sprockets will probably save you 8-10 pounds. So your bike weighs less.

This is also mass that needs to be spun by the crank. So your motor is doing less work to motivate the bike forward. This means quicker acceleration, less drag when you let off, and easier transition from side to side due to improved gyroscopics.

just replied to the other one with much the same as fiero - although I answered your can questions.
for now

Answer above says it all, and anyone who has done this mod can tell you that there is a very noticable difference, especially when you pair it with an exhaust and PC. If you are going to do this mod, I would seriously recommend a good dampner to go with it.....without it, you are a tank slap waiting to happen. :twisted:

I am guessing 15/50 is the best gear ratio set up???

15/50 will give you an incredible amount of acceleration. However you need to be prepared for it. Most people who try to ride my bike can't keep the front wheel down in 1st-3rd. I've ridden it this way for thousands of miles and can run it to the very edge of wheelieing and the very edge of breaking the rear loose. But again this is a significant change over stock. On the street I would probably go back to 15/49 or even 15/48 if I had a lot of highway rideing.

At 15/50 I'm at 8500rpm doing 80 on the highway. That's spun up pretty good and makes for a very buzzy commute. But the performance improvements are worth the drivability issues in my eyes.

what does 1....2.....&..3 top out at on your 15/50 set up? I don't know what ratio to get!! 15/48, 15/49, or 15/50. What is the over all best setup? I want the 15/50 but I am afraid that it is too low. ...............Ok I am looking for a set up that I can race a 1000 hang if not beat him and still top out a about 130-160mph.

Just go nitros :lol:

With 15/50 I can pull away from my brother on his 929. I don;t get as much shoulder to shoulder with big gxrs because I can usually lose them through the tight stuff at the track.

As far as speeds for each gear, check out this speed calculator (http://www.yzfr6.net/sprocket_speed.php). You can plug in the different sprocket choices and get an estomate on gear speed. And ask for which is best?. really depends on your riding. If you want acceleration obviously lower is better 15/50 or even 15/51. But then you start to have sooo much acceleration that it's hard to get it to the ground. So you might try a taller gear, like 15/49.

Also you have to remember that when you change your sprockets your shift points are going to change. So if you were insay 3rd at 60mph and 6k r's. Now could be in 3rd at 60 at 7500rs which means you have more motor on tap to work with. Gearing is a very personal and secretive. What works for me may not fit your style and vice versa, it's very black magic.

Thanks for all your help. :thumbup:

one other think I wanted to ask. Will I need a speedo calibrator after the gear change? I am guessing I do.

You can get a "yellow box" to heal your speedometer if you really want to. I just think about it in my head and know that I can be 10-15 mph over the speed limit and still be legal.

Does it matter if it is gold or not??? I am assuming looks more than anything
