Disabled Flapper Valve?
Hello all experienced fellow Honda SP1/RC51 lovers (2001 model) - mine has a plug on the flapper valve, does that stop it affecting the performance? Or do I have to remove the little flap as well? I tried to move it with a screwdriver and it definately wont move disabled, these SP1's are rare in Australia so maybe someone in the future wants a flapper valve...... Secondary question, what do fellow users think of the Power Commander Maps that are free on the website? Is it worth the extra $$$ for 1 HP or do custom maps rule?
