Easy to pull off Kevin just remove the front cowl give it a spray with with a mass cleaner and try before assembling the cowl gone through three in 16yrs ownership. If you need to replace I found the pattern ones just as good. The air filter is Low on the series1 also check the air tube it sits very close to the tyre it may touch at full lock. I had a small wear hole in mine and sucked debris onto the mass sensor.
