I know one of the things yamaha did to help increase the bottom end on the new r6's is the addition on the velocity stacks... I was wondering if they make the same things for my 06 r6... I feel like im raping the bike everytime i wanna get on it.

I know a -1 in the front sprocket will help out a bunch but i wasnt wanting to mess with my rpm's anymore since i already have the +2 in the rear. I currently have a mjs header with a gytr pipe, power commander (grave full system map) and rear sprocket. Is there anything i can do to help the bottom end power!?!

Which power commander you running? III or V?

Velocity stacks are way more expensive than the sprocket.

I'm running the MJS Header, GYTR pipe, and using the PCV map that Mike from MJS preloaded on it, along with the -1/+2 sprockets, and am very happy with it. The sprockets make the biggest difference, and it's not going to hurt the bike to spin a little higher RPM. Even Yamaha says anything under 8k RPM is fair game for extended periods. I cruise on the highway right at about 7900 RPM with my sprockets.

I have the PCIII, ive been looking for a good map to go with my system for a while. I have a pretty big flat spot at around 3-6k, then after 6k its like i just got a kick in the ass....lol

But just keeping up in traffic at around 60mph how many rpms do you think your turning with the -1/+2?

Smoke, your kinda stuck where you're at unless you pony up some money... I've been trying to correct the same problem, only between 7-10K.


Either JETT Tuning reflashes your stock ECU, you buy some '08+ throttle bodies and ECU, get a -1 countershaft, or buy a liter-bike. Cheapest would be the addition of the countershaft sprocket.

Currently I have a PC3, MJS header with Scorpion slip-on, -1 +2 gear and don't have a problem getting out onto the track but at corner apex when rolling on I can get stuck in the flat-spot I have when behind other riders (like liter-bikes with lower cornerspeeds and enough grunt to make up for it at the exits).

Most of the velocity stacks that are out on the market are for higher RPM gains, at the EXPENSE of lower RPM performance. What you would need is a set of longer stacks, the replacements I've seen are shorter.

The sprocket change is your best bang for the buck.

Run the akra full system map, the graves map is pretty fat, running the akra map will lean things out for you for sure.

If you had the PC5 we would send you a custom map that we have that works EXTREMELY WELL.

But for now def. try the akra full sytem map.

Thanks for your business!

Unfortunately, you are riding a 600cc inline motorcycle. You are not going to get v-twin-like torque even on a liter bike. I think the sprocket route and maybe custom map would help a little. Haters will hate, but I was having the same thoughts as you and am now riding a buell xb. A lot of what they say is true. The tranny sucks, hard to find neutral, clutch is heavy, but it's the most fun I've ever had on two wheels. I'm still looking to pick up a r6 raven in addition to the buell. Good luck.

Sorry to say, but it's an R6...it's not suppose to have any low end or midrange. That bike is designed for 1 purpose, 9k+ on the track.
