Im interested to learn more about the X1 systems as well as Im looking at that style of intake for a custom project,
So, i cant directly answer your question, but more helpful would be to know for example your area, elevation, type of fuel, condition and type of plugs you are running, have you checked the basics like Spark plug wires, intake air fliter, fuel filter, any modifications such as intake, exhaust?
All of those can be a factor. here in my area, (Oregon) they heavily oxygenate the fuels, and we are in the midst of a switch from winter formula to summer formula which has resulted in high fuel prices recently (dont ask me why if they dump alcohol in my gas why i have to pay more). that alcohol is really hard on the bikes fuel systems and can have an effect. Try also running a bottle of Chevron Techron in it as well One of the few miracles in a bottle that actually work. Some like Seafoam, but find the full strength Techron, not the discounted watered down stuff. does a great job cleaning the system and helping smegma filled injectors.
probably best if you have it hooked up to a tuning system and have a look see, dunno if ECM Spy works on that. Im learning this stuff as we speak as well, Im told by experts in this area that you should consider an upgraded O2 wide band sensor, gives far more information.
spend some time researching the tuning, even if you pay someone to do it, at least you can intelligently assess whats being done.
