| What is a high lift cam |
A high lift cam has a higher cam lobe, which pushes the valve
open a little earlier, and close later, and/or pushes the valve a little
farther down, |
Profile of a standard cam lobe
(lobe in red)
A fatter lobe gives you a valve that opens faster,
and closes later
|
A fatter and ligher lobe gives you a little more
boost, but these need race spring kits.
|
| What do high lift cams do? |
As they open earlier, and close later, they allow a little more
air/fuel mixture into the combustion chamber. This gives you a blittle
more (or a lot) acceleration. It also helps a little with exhaust
gasses. |
| Is there anything I need do to
if I buy one? |
You might have to replace the springs with some
high lift cam, race valve kits are available for same machines |
| Anything I should know |
Yes, running your engine faster can make your engine wear out faster,
so don't expect it to run for as many miles/Km's.
I know that there are some different high lift camshafts, some
will give you faster mid to high range power
You might need to re jet the carb(s) sorry, I can't help you
much on that, a dyno jet will let you know for sure. |
