![]() I'm just so glad i didn't buy the '07 R1 like i was tempted to do a few months back when the hype was out there. The GSXR lost as much as 15 Hp in some spots with no gains anywhere. The Gixxer 1k was not(no PC yet it's an 07) although it was touted by FactoryPro as a Drop-in gain due to the O2 Sensor. The R1 was Dyno tuned & the powerband lost with the stacks. I would think that with stacks you would lose top end and gain mid and lower, It seems to me that they are like the intake on a car the taller the intake the Higher up the power curve the shorter the stack or intake the lower the power curve Last year my cousin in Cali had Factory themselves install and tune his 06 gixxer 1000 and he said the bike was a lot better in the upper midrange, too. I rode the bike before and after and it did wheelies lots easier and had to be more careful on freeway onramps. ![]() I haven't looked at how the stockers are.comments?Īs long as y'all don't have any kryptonite/I'm gonna be alright.ĭon't know about the 07 gsxr1000, but the R1 stacks worked a lot better in my friend's bike - the upper midrange was pretty wicked.

They have been tested them on track by World Supersport 600 teams to let them compare the new MWR VS against the YEC and all of them choose for these configuration.No power curves are available yet because our development was based on track data and feedback from the teams and comparison against others Due to the construction of the stacks it is quite well possible you need to leaner the fuel from the upper injectors (high revs) of the to two outside cylinders (less fuel blown away so more effective …. The installation instructions are also included, which is also included with each set. Only the YEC stacks are very difficult to obtain and cost around € 2500,. The first tests have already been done by WSBK & BSB teams showing that the MWR stacks deliver the same power as the official YEC stacks….
