I have a 2000 VMAX 225. Starts and idles great. Runs strong up to about 55-60 then flatlines. I had it out earlier this year with no problems (72 mph top speed). Haven't changed setups or anything. Once the engine tops out at 60 or so, If I jockey the hot foot around a bit I can feel the power kick in and boost me to 65-68, but then slip back down to the high 50s. I've checked my throttle cable and everything seems to move fine. Anyone fimiliar with this issue? Thanks

Where is the O2 sensor located? Also, I just remembered that a couple weeks ago I had to run 87 octane fuel in it. Since then, I have ran about 15 gallons of 92 through it. Could that have something to do with it? Thanks
