Making the sv quicker

[rs_tubby]

Now i know i havent got one nor have i ridden one yet but i am more into a bike which has quicker acceleration than top end, now i dont want a bike which only does 100mph but i have no desire to really go above this sort of speed, i have heard the sv naked sprockets will make it quicker but what will things like a K&N, exhaust system and a power commander do and what else could i do to it?? thanks for any help

When I got my bike(SV650S K6), it was happily capable of an indicated 147mph. Twice as fast as you're legally allowed to go. More than enough bike for the UK roads IMO (not taking into consideration things like suspension).

Then I changed the gearing, keeping the standard sprocket, but going up 2 teeth on the rear. I'm told this is the same as naked gears. At first, I noticed a massive difference in acceleration! Now it's not so noticeable, probably because I'm used to it. You do loose some top end, and a comfortable cruising speed is a little lower than it was before.

Next I removed the snorkel (slight increase in air flow). I didn't notice any power benefits here, but the induction roar was nice. I'm still running on standard a standard air filter.

I removed the snow shovel & fitted a smaller plate with an evotech tailtidy. Again, didn't see any power benefits. This & the snorkel have probably helped fuel consumption though.

Next was an aftermarket can, a high level Scorpion. Again, no noticeable power gain/loss, but stick it on a Dyno & you'd see something different on the graph. Again, this could of helped with fuel consumption. I'm not sure how a full system would affect the bike, especially without a Dyno run to re-map the ECU.

I reckon power commanders aren't needed, since you can re-map the stock ECU anyway.

A K&N high-flow air filter will obviously allow more air in, but all that's likely to do is lean out fuel mixture a little. It depends if your bike is running rich or lean as to the affect more air will have. It'll either get you closer to perfect air/fuel ratio (and therefore more torque at a given RPM), or it'll lean it out too much.

On a ride out yesterday, I was lucky enough to come up against a Ferrari 355 Spyder. For those of you that say an SV is not that fast, I promise you that the SV beat quite soundly the Ferrari from standing up to at least 70-80mph.
I know it is not big, nor clever, but the road was clear and this guy was trying to make a point. Bike is an SVS with race can and naked gearing, nothing else.
I was astounded how well the SV did. Don't tell me off for this bit of 'boy racing' :smt105
Anyway, £2,000 worth of bike 1 £70,000 odd of Italian Exotica 0. :smt025

no harm in that is there just goes to show that you dont need to spend silly amounts of money to get the buzz and beat a stupid ferrari owner. :D :D

Seriously, the guy seemed distraught. Lets hope he did not know much about bikes, and thought it was a really high powered sports bike that I was on.
If that was me, I would have gone straight home and put the car up for sale! :D

I am not sure of the ferrari stats but i would of thought that it would of been pretty close.....IMO the spyder was probably badly driven if you kaned it that badly! After all a car/bike is only as good as the monkey in/on it :)

I'll let you in on a secret here... A tuned SV isn't actually that faster in road terms than a standard one. I find mine much nicer and more rewarding to ride quick, but it's not going to leave you for dead... Unles it's on a bumpy road anyway :)

Indeed, not only that but the £many it'd cost you to get a significant gain, you could just have bought a faster bike to start with ;)

Anyhoo, a 14t front sprocket is a happy medium between 'pep' and reasonable revvs at motorway speeds on the SV ... and it'll only cost you a tenner and 15 mins to fit 8)

Mine's still about the price of a new one, mind ;)

I promise you that the guy in the Ferrari was on a mission. Heard him hit the rev limiter a couple of times, but then so did I. ;)
I say, soundly beat, at around 80ish (private road of course) the bike had about a two bike lengths lead. :smt025

I know, not big and not clever. :smt105

As i said before i dont want to make it into something stupid quick just something useable because to be honest where can you use a bike to 140+ on a uk road, i also want to upgrade things like the brakes to make stopping power a bit better, and what sort of suspension set up should i go for, i dont want to go changing the front forks to something else although i may change the rear if i can get substantal gains from it, i want the sv to sound awsome i like the sound of the quaill and the fuel ones, one of the reasons im buying one is because of the noise and i think it sounds naff with a standard exhaust, this is only my opinion as im a very quiet person but like everything else loud lol. anyone recommend me an exhaust although i dont want to be pulled up all the time!!! thanks

If you dont mind loosing a bit of top end, the TBH just gear it down. That'll give you better acceleration which should make the bike more fun.

Front Suspenion, change the springs ( do a search its been covered loads and loads of times ) and change the fork oil for heavier weight oil. Then not only will you have a better damped front end, it'll also mean you can get more braking power and feel from the existing front brakes.

As for the rear shock, I dont know enough to advise, but again use the search function as its a pretty common mod to do to an SV.

Exhauts, how much do you want to spend, If you want cheap but good quality, look for Carbon Can Company of Fuel on ebay, if you want to spend a bit moer have a look at a Remus. Theres a specific exhaust sub section towards the bottom of the forum, it has loads of info in it have a read. Link below

hi i have had a one off remus carbon fibre race system and air filter added but have had no joy i am at an advantage as i dont way alot so i do get a little more speed out of my sv but any ideas how i can increase the performance of my sv? all out it max's at 143mph not as i have tried of course :rolleyes: i have tried takin the snorkel out of my filter and re jetting but this just just makes it gargle and splutter at low revs also flames everytime i change gear at high revs

also i have a problem with cornering as i dont have the weight to hold it down:confused: any ideas would be great.

The big question is.. . . would you have beaten the poor mans farrari on a quarter of a mile straight?
besides the spyder is the worst one you can buy IMO.

i think some of the racers amung us may agree, you can really launch the sv if you get your gearing correct, there is a massive difference in thrust in the first three gears . . possibly forth too if you get your gear shift correct...
0 - 60 . . in seconds on the SV last time i saw one on the Quarter of a mile it pulled in @ about 9 seconds flat, that was standard with a race can.
some people put in tens of thousands to get a car that does that . . . My SV cost £4000.00 . . . nuff said lol, :thumbsup:

Gearing. Its the only way to make the bike quicker.

1 tooth up on the rear sproket is the difference between 'S' and naked gearing. Most people go up 2 teeth, some 3 with a longer chain. You can drop down 1 tooth on the front, which is equal to 3(approx) up on the rear

However, things to bear in mind. If you do any kind of past A road, or motorway riding, then it will raise the rev range, and i at least, found this annoying, as the bike was much more buzzy being about 900rpm higher in top!

K&N's, dyno kits, power commanders will only improve mid-top end range.

Anyway, how much quicker than 3.5 secs dow you want ffs ;)

Calling your bluff.:roll:

12 secs actually. A hyabusa struggles to break 10 secs

Really?:confused: one sec, checking the photo . . .

and you are Correct it was actually 12.35 seconds . . .

it was a very mean looking car in the oposite lane that pulled the 9 secs . .

feel a bit silly now should of realised !!! :smt095

But on a plus note 12 secs is still better than most cars :thumbsup:

Yep, Including a Ferrari 355. :thumbsup:

Sorry, I won't mention it again, honest. :roll:

I'd agree with that.
