02 650s performance?

[timclarke1]

just bought a mint 02 650 s with 16000 on the clock the guy i got it off said it was d restricted but i find the bike a bit dead with a top of about 90mph and it just wont keep up with mates on gsx 600s or cbrs

I got a naked 51 plate k1 and it reaches 90 easily (that had 13k on the clock when i got it) now has 17k and is still sweet as a nut.

Dont forget that the gsxr and cbr is a different engine with different power delivery.

Use the search function on here and you'll find loads of stuff on restricted/unrestricted power and indicated speeds.

It's definitely not producing as much power as it should if it tops out at 90mph. I know a few on here have reached over 100mph with 33bhp SVs. With the full 72bhp, that it should be providing, 90mph should be a breeze.

sounds restricted to me, mines a 02 sv650s and it'll easily go quicker than that.

[Biker Biggles]

When was it last serviced?At that mileage it needs a big(valve)service if its not been done.Whoever does that will soon be able to tell you if its restricted or if the power loss is due to other service issues like plugs,airfilter and chokes.

Admittedly, when I took my 02 650S round Snetterton all the 600 & 1000 boys were doing me on the straights, but I was still hitting 120mph on the back straight before braking.

I never noticed a massive difference with the 600's and could keep close enough if i slipstreamed to get by on the brakes remember seeing atleast 130mph indicated just before braking. Plus the sv seemed to get out of the corners better than some others.

[hardhat_harry]

I've seen 125mph on my 2000 Curvy

On a private road / track i hope ;)

[hongman]

Definately something up with that...as others have said, a full power SV will do ~130 (indicated).

How is the power delivery up before 90?

When I ride with my mates, on a long straight when I know they are going to pin it, I can keep up just fine til around 70-80 I think (must admit I'm not really looking at the speed then), but after that they zoom off (GSXR600)

You do realise that his curvy IS a track bike dont you...?:rolleyes:

Racetrack!!

[slinky]

mine starts to loose the punch at about 110 then i get scared at 130 but dont think it has got much more than that ... but 90 it should deffo hit!

Perhaps restricted .... could this be a carb balancing issue?

[yorkie_chris]

Nah balancing only really affects tickover and low speed, does not matter if they are a bit out at WFO, maybe a little more vibration but no power difference.

[slinky]

Thanks Chris! I didn't actually know but i'm learning haha!

[paiste]

My Curvy saw 140mph on Bruntingthorpes 2 mile straight :D
In reality though it was probably more like a real 120mph.

[yorkie_chris]

Most I have had is 135 indicated. That was 2 up downhill on a very long straight

[robbie09]

Sounds like what i say about my restricted bike.

Good to 90...anything above that takes a gust of wind or a favourable gradient! :P

That's good going. I was coming out of the then turn 2, hitting the power and redlining before changing gear and with head behind the screen, elbows and knees snug on the tank I don't think I went any faster than 122mph!! Perhaps if I carried more speed into the corner I could have got more (and braked later into the chicane type bit). :rolleyes:

Don't think i was carrying massive speed through the bend as i'd only been riding a couple of months at the time but i was getting a good tow from a bike in front. don't know exact speed as it was a really quick glance down as i pulled to the inside to go past before getting hard on the brakes. think there was a slight tail wind as well so i reckon that and the tow probably helped a lot

[timclarke1]

cheers lads for all the help shes goin to get booked in for the big service and if i can manage a micron end can so hopefully all will help. still a crackin bike and i will never forget my first bike
