Ben. I know you've done the swap but what all do we need from the SV and what do we use from the GS?

This is exactly what I used.
99 to 02 SV650 clutch friction disc and springs.That's it.Every thing else remains GS.I bought EBC knock off kevlar racing clutch discs. and Barnett clutch springs.It is an over kill on a street bike.When I do it over I will use EBC or Barnett street friction discs and springs.If the clutch is to stiff remove 3 of the springs and install 3 GS springs.Every other spring should be GS.This allows even presure on the clutches.Soak the friction disc in a pan, with oil that you will be using in the engine,while you disassemble every thing.Remember this,there is very little torque applied to the clutch bolts.Be careful not to break one.Also,don't for get to buy a gasket for the engine cover.Took me 30 to 45 minutes to do it,but I have done clutches on other bikes.So 1.5 hours for a first timer and a manual really helps.No adhesives are nessasary on the gasket.The oil will swell the gasket and help it seal.I had a small leak.After running the bike it went away.Dgyver looked at it and clued me into this.
Sorry for the 2nd post.The only difference between the GS and SV stock clutch disc and springs,that I know of is:1)SV quality and fit is better 2)The friction discs have a little more grip for the higher power than the GS 3)The springs are a little stiffer than the GS for more clutch holding power.This is from a visual inspection of both GS and SV stock clutch friction discs and springs.
what are the pros and cons to this MOD?
You can drop more power into the thing without slipping, and you can possibly run a longer mileage without losing the clutch. However clutch life is so totally dependent on how you use it. You can get 50K on a GS clutch like I did, or you can fry it in 1 afternoon.
The key to long clutch life in 1 sentence is this ... whenever you take off feathering the clutch you let it out fast enough and open throttle just slow enough that the motor is on the verge of stalling.
That of course is great for the clutch, but murder on the lower end bearings. So I'd add in 1 caveat. It should be on the verge of stalling, but it should not make the metallic tonking noise that it will just before it stalls.
Cool.

Lot less slipage,no slips during clutchless shifting,handles more power,lasts longer
The reason I did this is because, it was cheaper than a stock clutch and mine was slipping when I quit riding last year.The PO replaced the entire clutch assembly except the friction discs and springs.When I was getting my bike for mods,I was pushing the bike in what I thought was neutral.Turns out that the bike was in gear.2nd I think.That's how bad it was slipping.It was slipping a little when i got it.I took everyones advice here about changing oil and working the old oil out of the clutch.I started using 10-40 Valvoline motorcycle oil.The slipping cleared up but didn't totally go away.It was very unpredictable when it would lock up.So,I decided to completely redo the clutch.
I spent
$46 kevlar clutch friction discs
$10 Barnett clutch springs
$12 engine side cover gasket
$6 10-40 Valvoline motorcycle oil
$4 Fram oil filter with cover O-ring
-----------
$78 for clutch upgrade and oil change
Dealer ship parts
$76 $13 per clutch friction disc 7 needed
$30 $5 per clutch spring 6 needed
$12 engine side cover gasket
$12 $4 per quart their brand of 10-40 oil 3 needed
$8 their brand oil filter
-----
$138 for stock replacement clutch
See why I went with the clutch upgrade.I got the friction discs from ebay and the Barnett springs from Bob Broussard on here.He just happen to have a 6 on hand,so I bought them.Most anyone should be able to change clutches and oil for less than $100 in parts.Just have to be ready when a deal presents it's self.
Average - get the werase to call another mad sunday (or any other day you guys wish) bash ... and we do your clutch, maybe I'll ride somehting over ... like the nighthawk.
BTW you have GS headlight ??? I fit one on the nighthawk. I decided that its rectangular one looked retarded. The headlight bucket I used was a yamaha one from a old seca, and fit a headlight off the GS inside it. Perfect fit. I had to dent the back of the headlight shell, but it was already dented so no loss there. I slap some GS T/S'es on there and we're good.

Yep, still got it. Seems like no one wants to buy my crap :icon_rolleyes: I'll see when we can get together. I have to bring up my car pc to see if he can help me with molding the screen into the bezel.
