Default Re: swapping cams over to get more hp ?

I'm not sure about this fixation with trying to squeeze every extra ounce of performance out of the SV engine. I've gone down the full exhaust, filter and jetting route and yes my bike may be slightly quicker than stock, but if it is it's only marginal. Perhaps the cam swap is better bang for your buck. Ultimately though, if you want more power get a different bike. Just my two cents.

None of those you've done will do much for HP increase

Maybe not, but as with the cam swap they're popular mods. My point is that no matter what you do, the SV is never going to make more than 80 odd BHP. At the end of the day, people always want to tinker, that's half the fun of owning an SV I guess.

I'm with Pricey on this. the gains are negligible you want more power look at other bikes.

your not going to feel a gain of 5bhp from a v-twin and even if you do where is that gain going to be in the rev range. enjoy the bike for what it is and if you feel the need for speed then move up onto a larger bike. believe this or not but your better spending the money on the suspension as this lets you ride faster round corners.

Aye, but that's more money than a cam swap, which was the OP's original question.

I bought my curvy already sorted with a pointy cam swap carried out, carbs have been jetted up and K and N Filter fitted. Its running a full M4 exhaust system too.
Once I get the poxy ignition sorted I'll be taking it on a Dyno run and will report back.

So did no-one look at the dyno trace I posted? For sure the SV will never be a missile but the cam swap is cheap and makes a big difference to top end with no losses lower down. Can/filter makes only small differences and when you add the set-up costs it's poor VFM. I'm not sure how much the cam swap would yield with stock filter/pipe but the OP isn't going that route anyway.

As said somewhere, on the road the SV is quick enough, on the track you're going to get eaten by faster bikes. I've found that at medium-speed tracks like Cadwell, the extra power of the new cams is enough to bridge the gap to the IL4s and just about keep them at bay.

Yes, I've read it a few times & I'm sold on the cam swap as the best bang for bucks option.

I just need to pull my finger out & do it
