Title: Camshafts for ls650 ?
Post by Peter Fonda on 05/23/25 at 18:06:32

so I’ve got a 08 Suzuki boulevard ls650 s40, and looking to maybe swap in a cam, something that would help with some extra chop in the idle. Maybe even some more bottom end power. Right now the bike is all stock except for a Emgo muffler, and wouldn’t mind having a better air filter for it as well.

All of the available performance cams have very little valve overlap and they have no affect on how the engine idles - the engine idles and runs smoothly after installation.

The performance cams do add some torque and horsepower - they work even better with the addition of a Wiseco piston to increase the compression.

The available cams are the Webcam Stage 3 available from Lancer in the Marketplace section - or you could try and find a good used DR650 camshaft from the early model bikes. If you use a DR650 camshaft you will have to drill oil holes in the lobes to use it in the Savage, and I also drill the center hole to match the size of the hole in the Savage cam.

Ah, in other words I’m likely best to just leave it alone then lol unless I ever had to do the piston or something of such

Not necessarily, a cam swap is not difficult if you have some basic mechanic skills. A piston swap takes a bit more skill and a few more tools, and some more time, but is doable as well. Many folks here have done both successfully.

Swapping the cam would I really notice much difference ??
Like I did a stage 2 cam swap on a Honda 450r quad I had, and it made a big difference for mid to top end.
