loosing 800 rpm??
On my Ultra LX. last season I was at an even 8000 rpm and was doing 59.8 on gps. This season it will not go above 7200 rpm. I have not gps'd it yet, but it def does not feel like 59mph.
What could cause such a loss in rpm. I did not change up a single thing from last year? only thing different this year is the plugs I used. I went from the cheapest ones to the next level up.
Also, If I wanted to check compression in the cylinders, is there a fuse for the fuel pump? maybe one of my pistons is slowly dying. It sounds normal but who knows.

Your fuel might not be good.
Try another plug

Your rpm and mph don't match 8000 rpm should be doing 70 mph
