Its been dyno-jetted, k&n filter and has viper race cans, the whole stage one and been on the rolling road.
I'm lucky to get 70-80 miles when driving around towns.

So... anyone else been in the same boat and whats the best to do?
Shall i take out the k&n filter and fit bog standard or just change carbs with my standard set?
Not got the time to mess around wapping parts too many times.
