Pictured: (front)- After a standard valve grind, this Guzzi valve is still too pitted to re-use. By the time the pits are ground out, it would be better suited for use as a pizza cutter. (rear) - It is easy to see how the new valve saves weight and has improved flow characteristics. This valve is at least 4 grams lighter than the stock valve, making it easier for the valve springs to control, and an excellent choice when going to a lumpier cam |
Exhaust Valves: We use one piece stainless steel valves with
Black Nitroneg impregnated stems for superior wear and friction properties.
These valves are lighter than stock Guzzi valves, have better flow characteristics,
and are precision made to exact tolerances. Stellite tipped.

| Intake Valves: Precision machined to exact tolerances, these
one piece stainless steel valves have black nitroneg impregnated stems,
and are stellite tipped. They are lighter than stock Guzzi valves, and
have better friction, wear, and flow properties.

Valve Guides: We use valve guides machined from Ampco-45 material.
This has a greater resistance to wear because of a 4-5% nickel content,
and great heat conductivity due to approx. 80% copper content. Instead
of a groove and a clip, these guides have a ridge machined on their outer
surface.
These guides are available in the stock OD or in .002" or .015" oversize. ID is .3120" to allow them to be reamed / honed to a proper fit. Price: $30.00 / Pair (compare to $25.20 each OEM Guzzi List Price) |
| Cam: For a noticeable bump in street performance, we use a remanufactured
cam which has had a hard face overlay welded to the existing lobes of a
stock cam. Using the most advanced alloys, this process has proved extremely
durable. The cam is then reground to a new profile.
The grind we use usually works as a "drop in" cam, but clearances should always be checked to ensure minimum valve to piston clearance. (.050" intake, .080" exhaust), as well as valve to valve clearance. Other numbers for this cam: Valve lift: Intake .395" - exhaust .395" Duration: In. 290o - ex.290o Duration @ .050": in. 252o - ex. 252o Lobe Center: in. 106o - ex. 106o Intake opens 20o before TDC Intake closes 52o after BDC Exhaust opens 52o before BDC Exhaust closes 20o after TDC valve timing is checked with zero valve lash @.050" of valve lift running clearances are .006" in. and ex.
