Valve width and LIFT

Debit fuel gas can be pumped with the tide spigot wide umbrella. All the mechanics already know that. Accessed through how to change the position of the valve angle. Thus the more important high valve lift and duration should be increased. Of course, through the buttocks journalist.

Length also know that many are living well. The higher valve lift, will upraised cfm. However, do not fix the elevator at. Been hit piston and valve spring that is not strong.

Ideal limit, on average every 110 ducks and 125 cc high-lift valve about 6 mm. Cfm will be a number of large valve spring and is still considered safe. For a good distance main valve spring is not what I'm up to.

Cultivated distance main spring only half the oppressed. For the past when the spigot will close late because more weak. Even encrustation sound ... arises in the rough when the gas cylinder head in mock thinkers.

Distance main valve can be seen directly. Per valve, without pressure measured first. Then-pressed to what. Now, the difference in the length of the free without any pressure and the pressure is the name distance play spring.
