Approaching 55K and needed lifters again. Never really appreciated how it ran with the HD 255s, so had them change the cams at the same time. I got to ride it today while using the VTUNE function of the TTS Master tune. The motor runs much smoother??? (don't know how to describe it) and although the temp today was in the lower 60s it runs much cooler and I have to say I worked it doing multiple tuning passes. Anyway, since it was converted to a Trike, the power was OK but lacking. I'll tell you, this cam change completes may conversion process. This may sound funny,, but with this cam it feels like the motor isn't working as hard. I can't wait to see what kind of fuel milage it gets at 75 or 80 MPH. A few less gas stops going to Glacier National Park this summer won't hurt a bit! Ride Safe!
