So I want to change the stock lever on my 2004 GS500F because I dislike it, it's very flimsy and I'd like to adjust it. I've read here that people take an SV650 clutch perch and then change to an ASV lever or whatever.
Now my questions are:
1) Will any year SV650 clutch perch do, if not, what years will be compatible?
2) Will any ASV lever be compatible? Judging by the ASV website it says C5 or F3 lever for the SV650 perch.
May also just go for a cheaper chinese adjustable lever, not really keen on spending huge money for a lever.
Important thing is to ensure the amount of inner cable pulled when the lever is pulled to the bar is the same as stock lever. It's about the leverage ratio (distance between the lever pivot and the cable stop).
I hear you...which is why before I buy any parts I want to make sure everything is compatible. As an example, a 2001+ SV650 perch.

Disagree. The GS500 clutch lever has a much longer throw than necessary. A higher leverage perch and cable, such as from is a nice upgrade for the GS500. Just make sure to properly adjust it.
OP: I've used an 06 GSX-R 600 lever/perch on the GS500. It's not adjustable, but it certainly isn't flimsy. You can adjust the lever somewhat, even on a stock bike, by adding some slack to the cable. I personally prefer removing most of the slack, but there's honestly nothing wrong with this approach.
Check out the handlebar change video in the tutorial section and it shows me changing to a sv650 perch. You need the perch off the naked sv's
OK...I'm a bit confused now after reading more.
1) Joolstacho, what do you mean by "The GS500 clutch lever has a much longer throw than necessary"?
2) Why must I use a 90 degree bend cable as opposed to the GS500 stock 45 degree bend?
3) Slipperymongoose, I will watch your video now, but why do I need a perch off a naked SV? How will I know if it's off a naked SV? Also, what year would be compatible?
4) I'm looking at eBay and I see some '99 - '02 SV650 clutch perches -- would this be OK to get? Would I also need to get an SV650 clutch cable or will I be alright with stock?
Regards and thanks for the responses thus far.
Naked sv has handlebars like the gs which means the perch has a mirror screw hole and the safety switch mount too. You reuse your clutch cable. Unsure of the years it's in the video
The Gs500 perch angles the cable out at 45* from the handle bars. The 45* bend in the cable is OK for it to clear the gauges.
When you use a different perch, the cable comes off parallel to the bars and sometimes angled in a few degrees. Due to that and the 45* bend in our clutch cable, it runs right into your gauge bracket. You need a 90* bend in the cable to clear the gauge bracket. So that is why you need to change out the clutch cable when you change the perch.
(I have seen older GS500 clutch cables with a 90* bend.)

Interesting Burning1, Suzuki must have designed the system wrong then, so that the clutch lever cable travel is not correctly matched to the worm-drive travel that moves the pushrod.
(Wouldn't be the first time a manufacturer has got it wrong I suppose!)
Thanks! It is starting to become clearer now!
Major word of warning about my previous advice: The advice is on a race bike. I don't have mirrors, or an instrument cluster to worry about.

To be honest, I think a lot of bikes have a longer throw than necessary, but the longer throw is valuable for making sure the clutch is fully releases. I prefer a higher leverage perch, since it widens the friction zone, reduces fatigue, and provides greater modulation. All of this benefits a good race launch.
Once we're moving, we don't really use the perch.
Getting the ergonomics right is critical for high performance riding. Fixing the ergonomics takes priority over handling and power.
Hi guys, I'd like to check for one last time before buying these components.
My bike is a stock 2004 GS500F.
