top speed?

I put a trail tech computer on my 2000 Yamaha wr400f and i got up to 65 mph in 4th gear. I got up to 75 mph in 5th gear and I still a lot of throttle to go. My bike must go about 90 mph. The guy I bought the bike from said it would go 90 mph. Do you think it will go 90 mph? :thumbsup::devil:
