Took my old yzf 600r here for a tune up after letting it sit for about a year. Quick turn around time of a week and it was less than that of ridenow. Carb clean/synch, oil change and coolant flush/battery was all that I had done with the difference of $300 vs $800 from ridenow. Well worth it IMO as I'm to busy to do my own work anymore. Bike rode great after the service and never had a problem up until I sold it(6 months ago). I didn't have any issues like other reviews but honestly - if you have a Duc - they are not simple creatures and that would be something you take to a mechanic SPECIFIC to Ducs- not only for their experience but also for the price. I'd caution taking your Lambo to a Chevy dealer ;)
If you have a regular bike issue/tune up I definitely recommend Adrenaline.
