Speedometer Adjustable ?

Just wanted to say Hello New Member here. I just bought a 82 maxim 750 and love it. Actually my new bride bought it for me as a wedding gift. Its my first bike and of course i already have a qustion: My speedometer is off by about 10-15mph. When the speedometer reads 35 i am acutaly doing almost 50mph. Is there an adjustment for this or does something need to be replaced. Thanks in advance

 

Hi and welcome to the site .

Congratulations! And well done finding a lady with good taste in bikes!

Check the drive gears in the front hub to make sure there is no slipping which would give a slow reading. Make sure the cable is ok while you are there.

Calibrating a speedo is something best left to the experts, a hot rod/custom car or bike type place should be able to tell you who does them. Might be cheaper to get a new second hand unit.

But officer I WAS only doing 35!

 

What Kiwi said. Plus chack wheel and tyre size to see if they are standard. PO might have fitted a different size wheel. Unlikely but worth checking.

 

This may be a silly question, but could it be you've got a metric scale and you're expecting miles? Or vice versa? 35MPH DOES = 56Km/h ?

Out of curiosity, how are you checking your speedo? Pace car? GPS?

 

Welcome and congratulations to you both! Nice catch I'd say. Post pictures as soon as your able.

 

But 35 Km/hr indicated speed on your speedo does not equal 55 MPH actual speed! Good point though.

 

Thanks for all your ideas sorry i have not responded been crazy at work and i found a bigger problem. I was told my steering head bearings were shot so i just put it in the shop. I am hoping to have it back for bike week in Laconia Nh in 4 weeks. I will check all the things you guys suggested and put up some pics... Thanks again!
