You may be asking yourself, can’t most mechanics work on these new engines? I don’t want to knock the dealership were you bought your bike or the back yard mechanic down the street but think of it like this. If you owned and raced a formula one race car would you take it to the same mechanic that works on your family jelopy? The new four strokes are basically 1/8 of a formual one engine.

The new Four Strokes! Head design is what has made it possible for 4-strokes to compete powerwise against the 2-strokes. We use the latest head machining technology and can easily restore your lost power. Most shops try to use their old valve seat grinding and cutting methods and ruin the seats. Most of the time they just install a set of new valves and call it good. That doesn’t work on the high performance high RPM titanium valve head setups of todays race engines. The seats in the head should be serviced and the valves replaced just about everytime you do a top end and especially if you have reduced the shim size by .004″, or two shim sizes. Most of us in off road racing are use to the 2-Strokes. Would you do a top end on a 2-Stroke without replacing the rings or replating a damaged bore? Thats similar to overlooking your valves and seats.
