the engine? This winter my new XV 250 Star Yamaha sits in the garage covered over with 1/2 a mile on it. I got a heck of deal so that's why I bought it at this time. I've never had this style of small cruiser but now that I'm a senior citizen I had to step down in bike size due to arthritis. This bike has no tachometer on it. What speed is most comfortable for the ENGINE in high gear, I don't want to lug it or push it beyond the r.p.m's this engine was designed to run continuously like on a 200 mile trip. I want this to bike to outlast me and prevent premature engine problems. Any experts out there in this field. Thanks to all who answer.
