I've only just bought it, adey, a few people have said it was fast, and right etc but, To me its slow and isnt as revvy as I'd like. Takes at least 5 starts at the moment to get it to idle when cold. It starts pops, farts and cuts out. and continues to do this until its warm. You can hear the backfire through the inlet
Once warm it pops and flames on over run and kicks out black smoke when really opening it up... Im used to an evo 5 and then a zx6r b1h so its never in a million years going to feel like a bike. Its also f**king useless around town as you need to get the revs to around 2k for it to pull away smoothly. These little problems do not bother me for the price i paid for it, but I really wouldnt go out my way to get an ITB'd clio 172. Its just a massive pain in the arse. I dont think the clutch has been changed for anything other than standard.
It cannot be anything but the map tbh, as it should be smooth and useable at any RPM range. I know maps do not go out of whack as its a written program *if thats the correct term* Like you say adey the Bodies could need balancing but I cannot afford to do so until im back at work.
A friend loves it however, and says it goes well and is faster than his 172 ph1. . . It needs a rollin road session and a good check over from somebody who knows their ITB setups and the f4r engine. either that or im going to have to go to uni and get a degree in this shizzle and sort it myself. lol.
