Sung to the tune "Do you believe in magic?"

Do you believe in magic, that it can fix your bike?
Turn all them screws to make it right?
Do all them things with which you used to fight?
Master all those things you never understood,
And right all the wrongs that you never could?
If you believe in magic, that it fixes all illls,
We'll induct you into the category of

hey guys...
I am waiting for the Raptor, the corrector of all things evil, to arrive. Meanwhile, I actually got the bike running quite well by rejetting it from a horrendous 180 to a 152.5, while keeping the stock idle jet (47,5), swapping the exhaust to a more open BSM, and reverting it to a stock airbox from a K&N.
I love it the way it runs just now. So does my pillion passenger. What´s wrong with you all? Cool

Yep, the horror of it all, the stock vacuum actuated petcock.

Undecided

List of things he's tried:

Pulled and replaced stock air box
muffler
rejet
plug

Issues diagnosed

Sticky slide
Half spacer
Midrange lean
Ignition related

Now, let's see what remains after he gets his Raptor in place.

People wonder why I keep telling folks to yank the stock vac petcock off their bike first thing whenever they START their Mods -- because if you don't you get lost in all the muddy water that it creates spontaneously and sporadically and occasionally on its very own.

The vacuum level needed to run the stock vacsucker correctly DEPENDS on all the stock pieces being in place, especially on the air filter end of things. Start your mods before Raptorizing and that practically guarantees a world of confusion & trouble soon to arrive.

Sad thing is that folks flat screw their bike all up messing and fixing with this and that and the other thing and then have to go UNSCREW it all once the Raptor goes on and the murky water abates.

maybe because of that my bike runs so nice, stock petcock. Been there since 1993, 34000km or in miles 21126. Or might it be the old gas I use? Have gas that are many years and still do run an engine just fine.

In the US our fuel has 10% ethanol in it. The ethanol can dissolve rubber parts, and it does not stay fresh very long. Most small engine manufacturers for seasonal equipment like lawn mowers and chain saws want you to drain the fuel if the engine will not be used for 2 months.

The fuel you buy in Sweden is most likely far different than what we buy in the US, and you may not have the problems that we experience with the stock petcock. New owners have very often experienced very confusing and elusive problems with their bikes, and have spent a lot of time trying to find out why their bike runs so poorly. Very often it can be traced to the petcock - especially on bikes that have been sitting for a while. When dormant the fuel does not stay fresh, and the ethanol can work magic on dissolving the rubber parts.

Here in the US the stock petcock can go a long time on a bike that is ridden often enough that the fuel is kept fresh.

Sung to the tune "Love and Marriage"

Mods and petcocks,
Mods and petcocks,
go together like broken head-rocks

if you you do them backwards
your bike will do things wackerds

Remember now,

Get your Raptor in place first
then you problems won't be worse

Mods and petcocks,
Mods and petcocks,

I think he's saying he DOES run all the stock components and his vac petcock still works as designed. Which is the point being made with the mod boys here in America, you HAVE removed a bunch of the stock components so you shouldn't be expecting your stock vac petcock to function correctly any more.

And a bad vacsucker can mock so so many different issues, really it can.

Also, Sweden -- is it a graduated license country? If so, perhaps does his Savage might have a restrictor plate or zone under or in its rubber intake manifold construction? The Savage is sold in the graduated license countries as a under 25hp bike to meet all the requirements of a starter bike.

Wink

People keep noting that Savages in some countries use some strange carb modifications too
