Throttle plate / butterfly valve

[zedi]

Howdy,

Long time lurker finally getting round to posting and woefully asking for help, typical isn't it?

I've a 2001 SV650 which is in need of a throttle plate or butterfly valve depending who you ask and where you look! Somehow it's gotten out of shape and the valve no longer closes on the front, resting about 1/1.5cm from the idle screw.

Can't seem to find anything with a google search and could do without the expense of a new(old) set of bodies/carbs.

My own fault, lay her up for a while at my parents house as I needed the space come to pick her up she's all angry.

So in short if anyone has a suggestion/advice that doesn't involve buying another set from eBay I'd be very interested to hear :D


I'll see if I can upload the picture, mobile isn't loving this though..

Cheers :)


Edit: Crisis averted - Thanks @ SheepShagger :)

Not sure I fully understand - the plate isn't flat any more? I don't really get what you mean about where it comes to rest either.

[SheepShagger]

God knows how that would have happened, it's quite unlikely you'll find that part separate from the carbs, but i might be wrong.I have a spare set of carbs you could strip if required but would only sell them as a whole unit.

Sorry I could've explained that better, somehow it's warped inside there and doesn't fully close on the front which is why it's not resting on the idle screw and I figure that's the reason it's revving the bejesus out of itself when started.

When I came back to pick her up the grip was solid like it was seized up and I can only assume my dad (bless him) had been trying to force it open and possibly causing the issue?

The plate isn't round, I'm assuming it's supposed to be which is why I say it's warped/out of shape, it is still flat.

they are supposed to be oval'sh shape but flat. the pic you posted up looks like someone had used a screwdriver on an edge and indented it so its now fubar.

best thing to do now is get a set of second hand carbs.

by the sounds of it the linkage and transfer bar was just a bit seized and a spray of WD40 would have freed it up.

You'd have thought, a can of wd said otherwise ;)

Pretty much from a few phone calls I've made today they're not a part I can pick up..

WD40 is the work of the devil, in my experience after dissolving out any lubricant that may have been in there it replaces it with a sticky non-lubricating ultra-effective dirt attractant which causes future problems. Use oil containing PTFE for best results like 3-in-1 advanced lubricant, use WD to stop things going rusty or removing glue.

SV650rules - I swear you are my brother from another mother (and maybe R1ffR4ff too)!

Absolutely. The most over-hyped product out there.

Blapper, was your dad a traveling salesman ? I am in Shropshire and RiffR4ff from JAMOADR (wherever that is) -

[Blapper]

LMAO. I don't think milk floats went that far on a charge!

JAMOADR=Just Another Monkey On A Dying Rock :reaper:

and Yes.WD40 is pretty much useless.It's OK as a water dispersant,which IIRC it was originally made as but bugger all use for much of anything else IMHO.

these days I mainly use it for wiping the sh*te off my rear chain before I spray it.
