Hey guys i dont think my speed meter reading right cause when it read that im going 40mph it feels like im going like 30mph is there a way i can fix this ? really need help i dont want to get a speeding ticket

 

get a gsp and see how fast your really going..that should help from getting a ticket before you can replace the cable or something.. sorry but thats my 2cents worth

 

Compare speed with some one, or what gearbox and revs are you at.

They are the two easyist ways to check.

Also have you changed your ride height.
Lower to the ground and you feel like your going slower, higher like in a van and you feel like your going faster. Thats something Iv just noticed.
