Rejetting and such
 

Its only a week or so until I'm going to pull the SV apart and play with a few things.

Going to be a micron full system, fuel can cut down to 3/4 length, degutted air filter, raised tank 10mm

Based on info here:

And buying jets here:
http://www.allensperformance.co.uk/mikjets.html

Got some 152.5 mains, going to stick with the 17.5 pilots and raise the needle with 2 washers.
I have heard of some people talking of 160 and bigger mains, but I presume they are different jets using bigger numbers than the mikuni ones?

I was impressed with allens performance's service, delivery was very quick and prices affordable

You shouldn't need the shims, euro SVs have stepped needles like a dynojet kit so you can raise and lower them. Mine have a wee thin half-step shim in anyway but for basic adjustment you don't need it, just move the jesus clip.

Mine has 185s in it now, but that's with a pretty decent full system and the wide-open BMC race filter. With the desnorkelled stock filter it runs pretty rich. I can't think in Mikuni sizes at all but that seems like the right ballpark. If you need different ones, I should still have a wee selection box of jets somewhere with everything from DJ 150 to 175, which should cover you.

Were you planning to drill the carb slides? I saw Rob Numbers saying it wasn't a good idea a wee while back, which was news to me but was interesting, might be worth looking into that if you are... I did it myself but I can't claim it was an informed decision :D

Possibly, can't see that the slider oscillation people talk about is harmful, or avoidable in some degree.
Seems like a good idea so long as the hole isn't 1/4" or something daft, as then you'd get the stumbling problems that simple slide carbs have when you whack the throttle open.

Haven't a clue myself ;) I've got a set of undrilled slides which I might try out next year, that post got me interested. I'd fit them today when I do the carb heaters but there's really no point with the weather like this, can't test things properly.

Re: Rejetting and such
 

Also what sort of dyno to use?

I don't trust any of them due to the amount of information flying around, dynojet seems to read massively high, most of the braked ones add 30%, just for the sake of it, EC997's manufacturers think they're ace.

What I need is something thats going to read the same as what VOSA would use if I got pulled with regards 33bhp limit, so I can set it up for that.
I'm thinking I need a dyno thats going to put out true bhp accurately without putting 300 fudge factors into the mix just for the sake of fondling some power rangers bolloks.

Re: Rejetting and such
 

Yorkie are you still restricted to 33bhp?

Re: Rejetting and such
 

Aye

Re: Rejetting and such
 

Hmm. Haven't the slightest on that one. I go by the quality of the shop/operator rather than the machine, I'd sooner use YPE's DJ200 than most other shops, even if they had better hardware, since I know they can use it and they couldn't care less if I don't like the numbers. But your position's a bit awkward. TBH if I was you I'd stick with the filter as standard and just tweak the jetting to suit the system, but that's boring.

Re: Rejetting and such
 

So you're going to knowingly break the law?

Re: Rejetting and such
 

No, I'm going to set the bike up to make near on 33bhp, as I mentioned earlier, with use of a throttle stop. More torque than stock and some nice induction sound too.

Please don't point me to FI international website saying I need a certificate and have to give them all my money unless you can find a law saying I have to. (I get that from everyone whos read their website, they have a vested interest)

Edit: for the record, if I was going to knowingly break the law I wouldn't be daft enough to put it up on a public forum
