I have a 2002 500 traxster which I have had no problem with until now.It bogs out at higher rpm in mostly 4th gear but will also 3 gear some times. But I also noticed the speedo acting funny. When sitting still it reads 10 kms and hour and I rev it up in neautral the speedo goes up and down.First I thought it was a fuel problem.Removed the tank,lines and carb and cleaned everthing and still does it. Now that I think about it the bog and speedo problem started at the same time so I’m thinking eletrical problem now. Anyone with any help or simular problem much apprciated.
