Yeah Mr YC's. ;)

In regards to trying to say 'well it's suzuki's fault that's balls, ignorance is no defence in the eyes of the law.
Not worth it

Re: 33bhp Dyno Resutls
 

I think no offence has been commited. The only thing needed is some "proof" to insurance. I don't reckon this needs a real cert, after all they're happy with an uncalibrated dyno.

Ouch thats a lot

Im 17 1 yr ncb and paid <800 fully comp =\

I always thought that the exhaust wouldnt affect an ecu restricted SV because of the ignition timing being retarded. but then again it increases bhp with normal ignition timing so.

Re: 33bhp Dyno Resutls
 

Huh?

Restriction is by STV and fuel curves. Ignition map could be similar or even more advanced.

Exhaust difference would be tiny IMO. Though the slightly free'er flow is bound to affect something.

Re: 33bhp Dyno Resutls
 

I thought the ECU retarded the ignition timing to make it 33 bhp, so for that reason i thought no matter what mod you added which would increase BHP on a full power machine would have any sort of effect on the restricted bike.

Re: 33bhp Dyno Resutls
 

To knock 50% of the power off how far would you need to retard the spark!? So it is firing on exhaust stroke lol.

Any restriction works by reducing supply of air and correspondingly fuel.

Mods do make a difference albeit reduced in effect.

Re: 33bhp Dyno Resutls
 

Hairy muff, i see what you mean now.

Spose, Hindles shown us that! :P but surely the extra BHP ganed on the restricted bike from the exhaust is the sort of power youd expect to gain from a full power bike with that exhaust.

Re: 33bhp Dyno Resutls
 

What bhp gain? Where?

What you have is an overreading dyno! Dyno data is utterly worthless, unless you are comparing before and after runs within a decent time frame.
