Top end Tuesday!!!

At Highland Cycles we are dedicated to KEEPING YOU RIDING!!!  Part of that mission involves educating everyone on different types of periodic maintenance.  I know that we all drive cars that get tons and tons of miles before the motor ever needs anything other than an oil change but our little dirt bike motors are different.  The amount of horsepower that these tiny motors (YES even a 450 is relatively tiny) make means that the top endneeds to be replaced every 100-150 hrs of operation. 

On a 2 stroke that includes a piston, rings, wrist pin, wrist pin bearing, circlips and gaskets.  At Highland Cycles we also disassemble and clean your powervalve to ensure "like new" throttle response and power. 

On a 4 stroke the top end job includes a piston, rings, wrist pin, circlips, gaskets, cam chain and cam chain tensioner.  We will not do a top end on a 4 stroke without replacing the cam chain and tensioner. 

Right now through the end of February we are offering special pricing on parts for top end jobs because we want to get machines in now before they have problems and before we get ridiculously busy.    Below is a quick step by step of a top end on a 2 stroke.

Make sure you look closely at all of the parts you plan on re-using.  In the case of this cylinder it was good to go with just a light ball honing to put some crosshatch back in the plating to ensure a good ring seal.

At Highland Cycles we take great pride in what we do so we sign all of our pistons as a way of saying "Yep, I did that!"

Step 6: Fire that baby up and listen to the beautiful sound of internal combustion!
