Echo and ditto. Nice Sportster. I have own several and they are fun rides. Awesome sound. You are correct MJR, however the EPA is more than likely to cause HD to put water-cooled engines on all their bikes, as the very lean burn that is required to reach EPA requirements has caused several heat related problems in the "block Head" engine currently in production. Because of HD,s unique knife and fork rod and crank arrangement, the rear cylinder is directly behind the front cylinder. (No offset as found in other V twins with separate rod throws on the crank). HD's set-up is what produces the beautiful "potato, potato" sound, however, rear cylinder cooling has always been a throne in their side. Guess I'd better leave it at this, as their are folks on this site that really don't care to hear about Harleys..Pushing my luck here.
