Either it is time for a new speedo or I was doing 120mph on a nighthawk 450

I was doing ton up for sure. I seriously doubt I was doing 120 in 5th gear though. I am running an 18 tooth front sprocket instead of 17 have an emgo fairing on it shorty exhaust and jetted carbs with pods. My speedo has about 4600 miles on it and I put it on about 8 or 9 months ago. It's a mini gage from dime city cycles and I know the ratios are right. I may have mounted it a little firmer than I should have. Any recommendations?

I seriously doubt it too. But I'd keep that speedo. Its even more optimistic than I usually am.

Get a gps app for your phone that records top speed and strap it to your bike and do it again
I don't recommend trying to hold the phone at "120"

Mine (same speedo) reads a few mph fast.

Stick with the speedo. Its way ahead of the truth.

3 weeks ago it was at least within reason of being close because I was riding with friends and I asked them to pace me to see and mine was actually lower than one of them. This was weird though funny but weird. In general it is close enough to the pace of traffic/speed limits comparison. Is it normal for them to get wonky at speed? In any case I am not in any hurry to replace it funds are short and this is "good enough"

the nighthawk must have had both jato packs ignited
