Neptune for SV650

**Bombus** · 4th September 2006, 22:23

Pipe arrived on doorstep Friday morning (1st Sept). The next morning went to move Bike into light to look at fitting myself. Bike wouldn't move. First flat on a bike ever, & the tyre's nearly new. Rang shop about what to do & they said they'd pick it up on Monday. Thaught maybe they could fit pipe at same time & asked if they had a chain pipe cutter. They said they just used a hacksaw so figured I might as well do it myself. Took a while to get started but a $3.00 hacksaw, 1 blade change & the cut was done in a bit over an hour. Fitting was OK but there was a disconcerting moment when I thaught the screwhole on the new can wouldn't match up with the mount on the bike. Bro came round & we trotted off to bike shop to look at some new boots for him.
While there picked up on the idea of getting one of those little gas cylinders to pump up my flat. Figured it had gone down slowly & could see the nail so should be able to get it to the shop, save a bit & try the new pipe. Sounds great, & not too loud either but it was a faily cautious ride on a slightly flat tyre so couldn't say much about the performance.
Was wondering if anyone had anything to offer on this, recommendations & so forth that don't cost a bomb. The other mod I was interested was a screen (its a naked).. Cheers Bombus

those k3+ Sv650's sound the bees knees with open pipes on them. There are a few who race them so you may want to get in touch with those people (keystone19) to find out what mods they've had done to their bikes.

Alternatively Shaun Harris (kb name shaun) has set a fair few of them up for racing so im sure he can give you a few tips for better handling and performance.

I just brought my self a naked sv650k6 a few weeks ago... have just put on about 500kms. yesterday went for a cruise over to piha via scenic drive... wicked as road to break in a new bike. Im planning on going back to the shop in a couple of weeks to get a scorpion pipe fitted. they quoted $500 including fitting (only cos i got the bike from there). would like to hear a bike thats got a scorpion muffler before i commit tho.

So are you happy with the sound of the neptune? i am hoping the scorpion will be deep/throaty, but not obnoxious and annoying as i am a daily rider and dont wanna piss the neighbours off too much at 5.30am.

as for mods for the sv- take a look at www.svdownunder.com and www.sv650.org

they are quite a popular bike here and overseas so advice for mods is everywhere. Im going to fit a smallish Givi screen (about $150) as on the motorway/openroad its a little breezy.

in my view the best mod to do to a street SV is cartridge fork emulators, fork springs, decent tyres, and new shock if required ..... then bling it up if you have money left. Thats what I intended to do to mine, anyway. (before I sold it and bought a Hornet.)

I just checked out the specs for an sv650 on http://www.sv650.org/ and it says 0-60 mph 3.20 sec?? is that right? its very quick if its right?

I reckon I can do it in a touch over 4 / maybe 4 flat if its a really good launch. You'd have to be pretty light / good to do it in 3.2. Having said that I wasn't giving too much away to the I4 600's untill well past 100.

The exhaust is fine but if you really want to make the bike sound good then buy a aftermarket pipe.I have just purchased a Scorpion exhaust and will be fitting it over the winter period ready for next season(fair weather rider).The best system to get is the Renegade system if you have a spare £600 to spare.

A full system M4 pipe has the best dyno results of any other apparently and sounds the bees knees...

But at 72hp? My 1000 does 3.7 to 100pkh... granted its a 1985 and 260kg dry but still thats a bit off tho? I'd imagine high 4's to 5's?

Not quite sure what you're saying, you'd imagine high 4's to 5's for the sv of for the GPX?

I've seen the figure of 3.2 seconds to 100 for the sv along with a 11.8 1/4 mile time. I can do the 1/4 mile in 12.8, so I must be losing 1 second during my 1/4 mile run. I was guessing most of the time was lost during the launch, a bit of rough timing with a phone camera seems to confirm this.

Been Back n forth to work a couple of times now & would have to say the Neptune does exactly what I want of it. Adds that crisp burble to the exhaust note that comunicates the riding experience so well. It is textured black, the bike metalic gray/black so looks pretty good too..

the sv650 is only 180kgs so that (combined with a 65kg jockey) is an immediate advantage over larger/older bikes. Thats why i bought mine - its light, powerful, fast, and has bundles of v-twin torque... not as much as a twin 1k but enough for me. 3.2s would be do-able. id say that after 100kph they would lose out to a peakier IL4.

so if the sv is 72hp, how come the dodgy looking (haha, read "clone") hyosung gt650 puts out 79hp from a carby engine....

quote from www.hyosung.com.au
"This compact water cooled 90 degree v twin, DOHC 8 valve engine incorporates the latest technology and produces 79 horsepower (approx 70 rear wheel horse power). Designed in Hamamatsu, Japan, it sets a new benchmark in V-twin performance. It has dual Mikuni downdraft carburetors, low restriction stainless steel exhaust, environmentally friendly secondary air intake system, which meets all world standards, including euro 2."

Maybe the sv puts out about the same shaft hp but all the readings we have are from the wheel.....i think i answered my own question

How does a sv650 sound compared with the vtr? I heard a vtr and was amazed!

Yeah what this man said, sort out the suspension and they are epic . not cheap though, its the main reason I sold mine
