I went of 1986 Husky 400 carb to a 2011 Husaberg fuel injected but what the hell is that thing. I know it's a carb but I haven't see half the S@it on it.

The 39mm looks like the Jap style carbs which have a cast trumpet on the intake, which is shorter than the bolt-on trumpet on the KTM/Husa/Husq carbs.

The carb you got has got the longer trumpet so it should be OK.
I know there are 2 different elbows, one for 450 and one for 550/650, but I think they only differ in angle to compensate for the height difference between the engines.

Anyways, good luck.

and now get a jetting kit for it too!

The carb looks trick alright, I don't know what half the dials/screws do, but sure I'll learn

The jetting kit: it was set up to match the bike's manual as part of the built, but I'd say we'll need to mess around with it indeed. There's an aftermarket exhaust on the bike (Reno - anybody ever heard about these? barely any info online), so I reckon the standard settings may be off, am I right?

Oh and these arrived too... had a bit of fun with an online decal design tool, as they were doing good discounts. Probably a while before I get to see them on the bike though.

Well, after a few month break we're getting back into things (...bought more parts...)

Think we really replaced most of the bike at this point, so the next thing is consumables:

What sprocket ratios do people use on their 650s? Standard is 15/42, isn't it?

I was thinking of going 15/44 to get a bit more torque but still be able to do decent speeds. And something that won't whellie like mad and instakill me.

Where will I ride: local mountain roads, but some of them fast'n'flowy. Also planning to track it on our local track, which is NOT a supermoto track. But then again, also want to take it to the shit roads in the mountains that no other bikes will do... what ya reckon?

how's it coming along?

hagetaka

Almost done apparently! Might even be next week-ish.
Still need to decide on chain and sprockets though, haven't had the time. I've a few fast roads here so probably needs decent speeds. Then again, for speeds I have an Aprilia Tuono V4, so I'm willing to compromise, don't have to go 170km/h all the time

Not sure where to order sprockets in Europe, hard to find sprockets fitting FS650, are 570 the same? or any KTM sprockets? And then where to find supermoto sizes rather than MX sizes... thinking I should go 15/44 now for some decent speeds but good fun factor too.

15/44 sounds pretty high to me. Wheelie central!

Sprockets - be sure to get the correct front sprocket with the "lip" on it (i know there is some technical term, but that's what I call it) or your clutch slave cylinder is going to get chewed up (Hbg fron sprocket has a sort of built in spacer). Rears that aren't MX sizes are plentiful, so long as you are ok with Gold for the twin ring style, or silver and black for the JT steel sprockets. Any 2002-2008 125-525 sx/exc ktm rear will fit.

Shortest gearing I used on my 650 was 15/40 (suplied with the bike also 38/16 sprocket came on the bike stock).
15/44 is good maybe for small real supermoto/kart track use where you don't use 6th anyway for cruisin on the street I would prefer taller gearing.
I liked the bike with 15/40 was stil capable doing 180+ but you had to rev it pretty hard for that....
when you gear it to long (stock 16/38 ) the difference between 5/6th gear is huge you realy have to rev it in 5th before going to 6th gear or you feel the bike is to low in the powerband to pull decently.
Or did you already decide/buy sprockets
