My 1984 K100RT BMW would run horrifically rich and often stall in 95+ degree weather because of its vapor retrieval gas cap/tank and heat build up atop the engine in slow traffic. I'd need to regularly open the gas cap to allow pressure to release and normalize or simply ride with the cap ajar. I guess it doesn't get as hot in Bavaria as does Palm Springs or LA Ca.
I was very disheartened when in 2009 BMW didn't offer the updated K
1300
R in the US. And it was their recent discontinuation of the entire K1300 line that helped steer my purchase of the R3R.
Having the K1200R and R3R as stable mates is the perfect two wheeled dichotomy for me. They both can go stupid fast; but each does it in a way and style that fully entertains while still complimenting the other's approach.
