LOL. Treat the internet 98% of the time as the equviliant of reading The Sunday Sport and you will be fine

This is our A/F



As you can see, much more even than yours.

The A/F is much too high with yours! Take care for detonation!
If you get the A/F right (+-13) you will earn more bhp, that's for sure. But if you can do it on your own? I doubt it!
Just bring you bike to a experienced tuner and let him do the job. It will cost you more but it will be done perfect and you will have a nice running SV, like we do.

Just put the 157 mains in, seems to rev a little freer if that means anything.

Will go for a spin in an hour or so and let you know how it feels.


Taking it to the tuners, letting them dyno it and then making changes myself.
Can't see the point of, or afford to pay somebody £50 an hour to take the carbs off for me.

Agreed, the only thing I never did myself was bore out the engine. If you don't feel confident to do any DIY work yourself then it is best to get a professional to do it, plus there is a warranty of such if it goes wrong!

A Haynes manual is an excellent start for any newbies...

So far this bit of messing around has cost me
Micron pipes ... £40
Bits for repairing my fuel can £25
New air filter £17 (?)
Jets £10 ish

If I'd paid somebody to make those changes then it would have been a fortune, and completely pointless, the thing I like about the SV is there's loads of decent performance to be had (not just engine, suspension) for not a great deal of money, i.e gixxer front ends, rear shocks from other bikes...

Kwel.

Although most still wont or cant manage taking carbs off letting alone changing jetting. Even being married to Steve and having watched him work on bikes for years i only touch under supervision..even then i still get told off

Seems to be one of those things, you're either inclined towards messing about or not.
I've never been able to leave anything alone for long hehe, except my 125, mods on that were fairly pointless.

What about the 2 or more powerchecks?
If the 157's are wrong (ran 175's with a bmc) then your already down £90 or so as well as the back and forth trying things, 2 1/2hrs on the dyno's £125 job done in an afternoon, giving you more time to fiddle with other bits of the bike...or even ride it!
