I'd be very tempted to try the Yoshi cams at that price. I have done the 03+ cam swap and I like the way it widens the useful rev range as you can hold onto a gear for a bit longer. In the end you are not going to make a massive improvement in peak power whatever tuning you do to your SV and even a 15 year old IL4 600 sports bike will be faster. For me it is all about the way it delivers the power that matters. If you go for the 03+ cam swap you need to know that the timing marks for the original inlet cams when moved to the exhaust side will be all wrong. To get around this problem you simply align the original cam lobe peak to a reference point (say gasket face of cam cover) them swap the cams and make sure the lobe peak is still pointing to the same reference point. Sounds very crude, but it does work because even one tooth out on the cam chain to cam sprocket is very noticeable.
