On speedo sorry don't get offended i don't beleiving speedo readings, its not the cylinder intake its connected to the manifiold intake,do you really know that your revs drop as you go high on gearing, my four speed revs to 8.6k rpm in 3rd gear with sigma reading 89kmph, and in 4th it comes down to 8k
rpm with sigma reading 112.55kmph.

i have been having a fluttery bike when it goes to 3.8 k and it remains fluttery till 4.5 K and then boom it goes like any thing gets into the power band.

bro i m not talking about speedo readings,mine statements are on the basis of GPS readings.if i go on my spedo readings then my Rx is one fastest or may be the fastest over any Rx in xbhp.(my Rx shows 140+ on the speedo very easily)
My Rx hits 104-5 kph in 3rd gear with power box fitted which comes as stock part.I m clarifying cos as u said in ur post power box is only good for only 80kph speed whatever u do in modification of an engine.ya mine rx is not stock one and with some modification any rx can accelerate to 100 kph without losing much on rpm band.ya in 4rth gear there is some drop rpm and acceleration but not in 3rd gear till 100kph in my case.

thanks for technical and theoretical correction.BUT i m just trying to focus on its location near/in the engine.cos some times new members(but very few) don't know about the part and keep asking Via PM's.
an intake manifold or inlet manifold is the part of an engine that supplies the fuel/air mixture to the cylinders.
