So there's one cam for the intake and one for the exhaust. ? Anyone know the specs? ?Also, how optomized are these cams. ?Is there any room for improvement? ?Aftermarket options?

Swapping the stock exhaust cam with a stock intake cam is said to give a nice little increase in power. Some say around 7hp but I have not seen any hard #s yet. It is an old trick I've been told.

hihi,

i been looking for info on this.
i was told to change the exhaust cam to inlet/intake cam. and the mid range abt 7K onwards the respone will be big. on how much is the hp will it improve i am not sure.

Yea I'm for real. Most of my experience is on pushrod stuff. Performance wise I was contemplating a cam swap and maybe porting the heads. I doubt theres any room for bigger valves and I assume they already make them outta pretty light material to sustain such high rpms. I'm confused about the tuning requirements as well for mods like heads/cams for bikes.

I didn't want to sound stupid, but didn't really know a better way to ask.

I found a site w/ the cam specs for the busa. How much bigger can you go on lift w/ stock pistons? Does increasing duration do much for them? Is the duration rated at .050 lift like car cams?

I'm new to bike engines and just have a ton of questions to help me answer for myself where I want to go with the mods.

Mountainmotor and a few others should chime in here, there are some who know these motors all the way down to metallurgy...

As an ignorant layman, I DO know the valves lost 14.5 grams EACH going to titanium on the 08, so there is definitely room to improve there.

any advise on the cam?

After seeing pics of that tranny, it doesn't look confusing at all!


















Yeah right!
