REMARKS :
#
The original valve springs can handle a high valve lift, however they are very weak and cannot exceed the original rpm limit. For this reason, upgrading to Cat Cams springs is advised
#
if required, use extra shims to increase spring load
#
double spring PAC-D19864 can also be used on retainers 99351 and 99352(requires dedicated lower retainer and valve seal)
REMARKS :
#
These camshafts do not have a fuel lobe. To use these camshafts in carburettor engines (like the D14A1), an electrical fuel pump should be used
#
Distance between valve and piston should be 1.0mm at least:
-
check 5-15° after TDC on intake
-
check 5-15° before TDC on exhaust
Machine pistons if required. Wrong installation can cause severe engine damage!

ONLY for dirt track applications and pro street use with adjustable engine management or carburettors
