Has anyone put velocity stacks on a 2001 R1? Is it very hard to do, and is it worth it? Also, is there any other easy mechanical stuff that I need to do to squeeze out a little extra HP?

Yea I can change an air filter, do the velocity stacks sit below the filter or where exactly do they attach? I plan on doing a chain and sprocket change soon as well. Is the 520 conversion worth it or stick with a 530? You said I won't feel that big of a difference with factory carb settings, if I do the stacks do I need to adjust the carbs or have them jetted?
You have to remove the airbox to get to the stacks. Just pull off the factory stacks and slip the new ones on over the carb inlets. You will feel a bigger difference if you skip the velocity stacks and just adjust your carbs correctly. The best free mod is to richen up your idle mixture to about 3 1/2 turns out. Next I would clip off about 3/4" off the slide springs to increase the throttle response a bit. These 2 changes alone will liven up the motor a lot. What mods do you have on your bike already?
I would not install velocity stacks unless I had adjustable needles. I believe most of the aftermarket v-stacks for the carb'd R1's are focused on midrange and topend power, so you really need to set the needles for that. You should get adjustable needles in a jet kit, or you can order adjustable needles from the dealer but I don't know the part numbers.
I would stick to a 530 chain. The only advantage of a 520 chain is less weight, and that weight savings isn't much. The downside is a 520 chain doesn't last long on a 1000. Most of the racers on the big bikes swap out their 520 chains after a couple hours of use to minimize the risk of the chain snapping and causing a horrible accident.

Other than a vance and hines pipe which came with the bike, other than that Im not sure, I am going to yank the tank tonight and check the condition of the air filter. I dont' know if the carbs were adjusted when the pipe was put on so thats also next.

ColinP is right, on the street you won't notice a difference with a 520 chain. Stick with the 530 and go -1 up front. I would also install a Flo-Commander. I installed one on my '99 and it felt like I gained 5-6 HP.

With a slip-on, stick with the stock needles. I tried Ivan's with my slip-on and didn't notice a difference.

That looks promising, I read through the website and I guess I just didn't quite understand how that thing works. And I had a question or two, DO I need to tune my carbs before throwing that on there, and how much did it cost? How long did it take to install it?

They run about $140. E-mail Steve with any questions. Very helpful!

Takes about 1 hour to install and you should probably have your stock needles and original jets. Steve would know more about it so you should probably ask him.

Thanks for the help, I am going to look into getting one of those. It seems simple enough to do, Yamahog, do you have enough toys, you are about to run out of room to list em!

That is what I have been told as well. Ivan with Ivans performance products told me the same thing. BlurR1 has told me that they are a waste of money and by the looks of his mods, I believe what they say. Short stacks just move power from midrange to up top. Long stacks tack power away from top and move it to midrange. Basically if you race, they would be great for different tracks where sometimes you need topend, and others you need more midrange for comming out of a corner.

I would suggest getting your carbs sorted out to make sure they are spot on, whether or not you go with Ivan's Performance Jet Kit, is up to you, but having your carbs spot on will yield you the best overall seat of your pants difference. Then again they could already be spot on, but that is rarely the case. I have heard positive things about the flo-commander as well.

the previous owner removed my ex-up valve. i was looking at the dynojet kit and they say it is designed for use with the valve retained. does ivans offer a kit for use without one or should i replace this thing?.. also, which package should i be looking at for the flow commander? there are several for the r1 all around 149.99? thanks
