swapping cams over to get more hp ?

I belive I read it on the American sv fourm but wondering. A is it true or B is it total bill has any one ever herd of this it was something like repacing the inlet cams with another set of exhaust exhaust cams ?

It can be done, yes. I'm sure someone more technically minded will be along in a bit to elaborate.

Is it worth it for a couple of extra horses? Probably not.

Any more extra horses for me is fun more than worth it lol I like to tinker mine is a curvy just want to make some more go go power lol any help how to do this would be good

Pointy cams into a curvy engine is a well known improvement in HP for little or no big outlay.

Here's the how to

Some have swapped curvy cams into a pointy, but I forget which ones & the HP gains are relatively small compared to the above.

You sir are a legend for this I think I will do this and up my jets and aifiter up grade im off to a dyno this weekend with my bike as standard to see what im startimg with

I know

I've still got to do mine.

Let us know how you get on

It's an easy job, cams cost about £150, and that's all you need. Check the clearances but I will lay money they'll be identical to your current set-up. No jetting changes needed unless you have filter/can etc. that you haven't compensated for. What do you get... top end power!

From stock to noisy can to cam swap.

Well once cams are done I will be upgrading filter and jets my idea is more air more fuel = more bang haha I alredy have a can on and iridium plugs dont no if the plugs make much difference on that dyno ? Is the green the stock one ?

I know that given the money the ideal swap is ......
Pointy inlet to Curvy Inlet
then curvy Inlet to Curvy exhaust

Now come the idiot questions

Seeing as second hand pointy cams are as rare as rocking horse doo-dah what sort of gains would you likely get by having Curvy inlet cams on both the inlet and exhaust ? On a Curvy that is.

As the Pointy inlet cam is only 0.6mm (?) higher than the stock Curvy inlet, are most of the HP gains from the Curvy cam swap because of the 2mm increase in the height of the exhaust cam ?

Im just thinking of a cheap and easy way of getting a few more HP from the SV and if this works I'll give it a go

Cheers guys and gals
