pegged power valve carbon reeds removed snorkel 240 main jet standard front pipe (de restricted?????)
i only fitted the main jet today and it doesnt like it splutters on low revs and feels sluggesh gona change it back tomos only reason i fitted a 240 main jet is i was told it would be much quiker my topend speed is 70/75 before i fitted the new jet any ideas or suggestions welcome
Youve pretty much done every chavvy mod you could find havent you lol, atleast you haven't cut the 'restrictor' from the intake manifold.
If you have a powervalve servo reconnect it up(make sure you set it up properly), put back in your snorkel to the airbox, drop the main jet to about a 220, and make sure your front pipe is deffinatly derestricted.
when everything is working fine you should expect it to top at about 10k in gear six, or about 10.5k in most other gears, but tbh the power band(on my bike) is dead by 9.5k.

that might be your problem right there, from personal experience i wouldnt go lower than a 210.
what year is yours? i think the old 88' models had a different carb so it might be abit different.
and put your airbox snorkel back in! when you say wont go past 9k, do you mean in every gear? anychance it was imported from germany or similar?

On a 2003 model there isn't a wire to earth out as such, it's got a reedswitch in a long grey/white box behind the speedo. And to my knowledge that shouldn't be cut or earthed out. The reedswitch should just be pulled out (Not by disconnecting the wires) and covered in waterproof tape to prevent any water getting into it. If unsure just go to the main site and check the de-restriction guide for the same year model as yours.
sounds like your exhaust system is blocking it mate, have you checked that your front pipe is gutted? try removing it and sticking a metal coat hanger around the loop at engine side of exhaust, if it gets stuck then its not a derestricted pipe as you will be hitting the internals that need to be removed also check the sleeve at this side is removed and that the exhaust you have is from a early model as these are the only exhaust you can derestrict as standard the more modern ones dont allow you too, failing that borrow a dep pipe off some1 for a minute
