hey guys i went and had my chain and sprockets replaced and the mechanic who test rode it afterwards told me the bike is only running on three cylinders... i had noticed one day that the power and sound were different all of a sudden but wasnt quite sure what it could be...

my question is what should i look at first before i have to pay them to diagnose it... spark plugs? wires? what would be the most likely, and how hard are the plugs to get at on these things?... any help and advice would be appreciated, thanks!...

 

I would pull the plugs out and see what they look like and probably replace them before taking it to a shop. They are not that hard to do as long as you have the special socket that is in your tool kit. Slow down when working on the bike and you will go faster.
