2003 sv650 parts & advice :-)

Keep your eyes peeled for a used Penske or Ohlins shock.

If you're hellbent on putting some other bike's stock shock in there till you either find or save up for a Penske or Ohlins, then whatever... it's not gonna be WORSE than the stock shock, but you're gonna wanna get rid of it if you ever ride a bike with the right shock so you'll just end up swapping shocks twice instead of once. I'm more of a subscriber of the "do it right the first time" method.

+1 on vortex fairing stay. Not many other options out there.

Racetech springs & Emulators are the typical go-to for fork upgrades. That's what I raced on last year until I had Peter Kates work his magic & put together a custom cartridge set-up, but the emulators were good enough to get me into the sub 1:20's.

Exhaust I wouldn't worry about too much right now. That can come later. Concentrate on getting the bike track worthy first (suspension & tires) then worry about trick bits later.

I plan on having this bike be entirely function over form. The exhaust was on my wishlist just because I would imagine this thing to be pretty damn heavy and it looks like it could even drag. If that doesn't seem to be an issue for anyone else, I have no problem leaving it on. I'm definitely gonna have gmd work the front end and geometry but I wanna figure out what tires and stuff i can get a hold of before I do that. I'd like to have it all done at once ideally.

I think i'll start taking this thing apart just for funsies to get to know her a little...

[OreoGaborio]

Oh a full exhaust or even a slip-on is definitely functional on an SV, it's just (in my opinion) lower on the list of priorities than suspension & tires. Hell, to race in Middleweight Production Twins you actually have to KEEP the stock exhaust.

[Alvecchio]

I think I'll just keep an eye out for a used exhaust if I can find one. I'm definately going to look for a penske shock rather than using a swap in from another bike. How bout a chain? Any recommendations?

ive heard a 520 conversion will save you a little weight. im keeping my 525 chain till i need new sprockets, then im replacing them all at once. i tend to use DID cains.

520 will essentially save some weight but 520 stuff (chains, links) are easier to find when/if you need them.

Penske or Ohlins. Either one will work well.
If you NEED a new chain & sprockets, then you might as well replace with a 520 kit. Doesn't make too much difference what kind. 15/47 would work probably well for ya.


If you're curious, I ran 15/46 Vortex sprockets & a DID ERV3 chain for the last two years.

What's the stock tooth count? And was that 15/46 with the stock motor?

I think 15/45 is stock for the S model. And yes, stock motor (minus pipe and pcIII)

you might want to mention your goatee adds 5 horsepower to any SV motor.

Does the pc make a big difference with throttle control? Particularly on/off throttle? Or more for power?

Wtb: goatee

I dunno about the PC. Never ridden a 2nd gen sv w/o one.

Yes and Yes.

When you see PC3, think carb jetting and what that can impact.

The pc3 will smooth out the on/off throttle and even though it will add HP it won't be the kind of gains that you would expect from a jet kit on a carb bike. I've also read that k&n filters don't make a difference compared to the stock filter so if you still have the stock filter don't be in a rush to change it. Just change it when its time.

[Alvecchio]

I wasn't planning on doing anything for power but if the pc3 will help with throttle response and stuff then I'd be all for it. Again, not familiar with these so I don't know if the stock fueling is pretty good for the track or if it needs some tlc. Guess I'll just clean and lube the chain for now and keep the stock gearing as long as they appear to be in good condition.

[OreoGaborio]

pcIII should be low on the list of priorities

(scribbles out "pc3" and writes it in at the bottom..)

[OreoGaborio]

On the topic of priorities,

get what it NEEDS first
then tires
then suspension
then whatever else.

Thats precisely the plan. Speaking of which I will need some body mounts for the left and right sides. Took a look at a new S and it turns out mine snapped right off. Also wondering if it's practical to replace the radiator with a newer year one. Apparently the 03s are bigger and have a tendency to bend when they go down. Would be wondering about mounting points for bodywork and/or overflow bottles?

overflow bottles...zip ties

bodywork brackets...1/8" aluminum stock from home depot and a dremel/hacksaw. bend away.

[Charlief]

Just make some body mounts out of 1/4" AL ...... bend to desire.....drill holes....mount

lots of SV guys on here that know how to build a sweet track bike on a budget.

I want to say that some people run a gsxr radiator, but don't quote me on that.

[Alvecchio]

Alright so body mounts solved. Any other Input on the radiator?
