My view on this subject is this. The SERG looks great without the lowers, but still I got them for wind/rain/cold protection. I rode the first 5 months without and was fine. When I had my lowers painted and installed I realized that I had taken the bike to another dimension, Full Bagger. the color scheme works great, but when I rode it the first time I knew I liked them on. Now granted, it has been cold and the protection works, I said that when the temps rose to the point that it was detrimental to the motor I would take them off. Couple weeks ago we were in the 80's so off with lowers. was watching the oil temp and it still stayed around 227-230., just fine. I put them back on for the trip to Eureka Springs, and I again will watch the temps, but after all the mods and TTS, the bike is running much cooler.
As far as more to clean..............ya, so what.
